Answers

Answer 1

The product of the molecule in figure 3 undergoing a Birc is cis-4-pent-2-ene.

The Birc reaction is a way to convert an alkyne into a cis alkene. It involves the use of a catalyst called Lindlar's catalyst. Lindlar's catalyst is a combination of palladium and calcium carbonate that has been treated with lead acetate and quinoline to make it less reactive.

The reaction is performed in the presence of hydrogen gas, which helps to reduce the palladium and make it more effective.

The inductive effects of the [tex]-CF3[/tex]group are far greater than its hyperconjugation effects. Bearing that in mind, let's draw the product of the molecule in figure 3 undergoing a Birc.

As we can see in the given structure, there is an alkyne present in the molecule, and we have to convert it into a cis-alkene. Therefore, we will use the Birc reaction to convert the alkyne into a cis-alkene.

The mechanism of the Birc reaction includes the use of Lindlar's catalyst (Pd/CaCO3) in the presence of H2 gas. The alkyne is added to this mixture to obtain the desired cis-alkene as the final product. The reaction is shown below:

calculate the number of grams of water produced when 3.0 mol ammonia, nhs, reacts with excess oxygen, o, according to the equation below: 4 nhs(g) 5 02(g) -> 4 no(g) 6 h20(1)

Answers

When 3.0 mol of NH₃ reacts with excess O₂, approximately 81.072 grams of water are produced.

To calculate the number of grams of water produced, we need to use the balanced chemical equation and the molar ratios between the reactants and products.

From the balanced equation:

4 NH₃(g) + 5 O₂(g) → 4 NO(g) + 6 H₂O(l)

We can see that for every 4 moles of NH₃, 6 moles of H₂O are produced.

Given that we have 3.0 mol of NH₃, we can use the molar ratio to calculate the number of moles of H₂O produced:

Number of moles of H₂O = (3.0 mol NH₃) × (6 mol H₂O / 4 mol NH₃)

= 4.5 mol H₂O

Now we can convert the number of moles of H₂O to grams using the molar mass of water (H₂O):

Molar mass of H₂O = 2(1.008 g/mol) + 16.00 g/mol = 18.016 g/mol

Mass of water = (4.5 mol H₂O) × (18.016 g/mol)

= 81.072 g

Therefore, when 3.0 mol of NH₃ reacts with excess O₂, approximately 81.072 grams of water are produced.

Answers

The percentage of glutamate that is protonated at pH 6.0 is found to be 99.3%.

To calculate the percentage of glutamate that is protonated at pH 6.0, we need to consider the pKa of the glutamate R-group and the pH of the solution. Using the Henderson-Hasselbalch equation, we can determine the ratio of protonated to deprotonated forms of glutamate.

The Henderson-Hasselbalch equation relates the pH of a solution to the ratio of protonated (HA) and deprotonated (A-) forms of an acid. In the case of glutamate, the pKa of its R-group is given as 4.2. At pH 6.0, we can calculate the ratio of protonated to deprotonated forms.

The Henderson-Hasselbalch equation is:

[tex]pH = pKa + log\frac{[A^-]}{[HA]}[/tex]

Since glutamate acts as an acid, the deprotonated form is A- and the protonated form is HA. Rearranging the equation, we have:

[tex]\frac{[A^-]}{[HA]} = 10^{(pH - pKa)}[/tex]

Plugging in the values, we get:

[tex]\frac {[A^-]}{[HA]} = 10^{(6.0 - 4.2)}[/tex] ≈ [tex]10^{1.8}[/tex] ≈ 63.10

The percentage of glutamate that is protonated is given by:

Percentage protonated = [tex]\frac{[HA] }{[HA] + [A^-]} \times 100[/tex]

Using the ratio obtained above:

Percentage protonated = [tex]\frac{1}{[63.10 + 1]} \times 100 \approx 0.993 \times 100[/tex] ≈ 99.3%

Therefore, approximately 99.3% of glutamate is protonated at pH 6.0.

Answers

When 56.3 g of C₃H₈ combusts, approximately 91.902 g of water is expected to be produced according to the balanced combustion equation and stoichiometry.

To determine the amount of water produced when 56.3 g of C₃H₈ combusts, we need to balance the combustion equation and calculate the stoichiometric ratio between C₃H₈  and water (H₂O).

The balanced combustion equation for C₃H₈ is:

C₃H₈  + 5O₂ → 3CO₂ + 4H₂O

From the equation, we can see that for every 1 mole of C₃H₈, 4 moles of water are produced. Therefore, we need to convert the given mass of C₃H₈  to moles, and then use the stoichiometric ratio to calculate the moles of water produced, and finally convert the moles of water to grams.

Molar mass of C₃H₈  = (3 * 12.01 g/mol) + (8 * 1.01 g/mol) = 44.1 g/mol

Number of moles of C₃H₈  = 56.3 g / 44.1 g/mol = 1.275 moles

According to the stoichiometry, 1 mole of C₃H₈  produces 4 moles of H₂O.

Number of moles of H₂O = 1.275 moles * 4 = 5.1 moles

Finally, we convert the moles of water to grams using the molar mass of water:

Molar mass of H₂O = (2 * 1.01 g/mol) + (16.00 g/mol) = 18.02 g/mol

Mass of water produced = 5.1 moles * 18.02 g/mol = 91.902 g

Therefore, we would expect to produce 91.902 grams of water when 56.3 g of C₃H₈  combusts.

Answers

In this case, with pKa1, pKa2, and pKa3 values of 1.9, 6.7, and 11.9 respectively, the solution is in the region where all three species are present.

The molar ratio of PO43- to HPO42- can be determined based on the Henderson-Hasselbalch equation, which relates the pH and pKa values. By considering the pH of the solution and the pKa values, the ratio of molarities can be calculated.

The Henderson-Hasselbalch equation can be used to calculate the ratio of molarities of PO43- and HPO42- ions in the phosphate buffer solution. The equation is given as:

pH = pKa + log([A-]/[HA])

In this case, [A-] represents the concentration of the conjugate base (PO43-) and [HA] represents the concentration of the acid (HPO42-). The pKa values given are 1.9, 6.7, and 11.9 for the three ionization steps of phosphoric acid.

Since the pH of the solution is 11.0, it lies in the region where all three species are present. Therefore, the equation needs to be applied to each relevant pair of species. The ratio of molarities between PO43- and HPO42- can be calculated for each pair using the Henderson-Hasselbalch equation and the respective pKa values.

For the first ionization step (pKa1 = 1.9), the equation becomes:

11.0 = 1.9 + log([PO43-]/[HPO42-])

Similarly, for the second and third ionization steps (pKa2 = 6.7 and pKa3 =11.9), the equations become:

11.0 = 6.7 + log([HPO42-]/[H2PO4-])

11.0 = 11.9 + log([H2PO4-]/[H3PO4])

By solving these equations, the respective ratios of molarities for PO43- to HPO42- can be determined in the pH 11.0 phosphate buffer solution.

Answers

The molecule CH₃CH₂CH₂NH₂ (propanamine) has a higher vapor pressure compared to CH₃CH₂CH₂CH₃ (butane) when measured at the same temperature.

Vapor pressure is a measure of the tendency of a substance to evaporate and is influenced by intermolecular forces and molecular weight. In this case, propanamine has a higher vapor pressure due to its ability to form hydrogen bonds, which are stronger intermolecular forces compared to the London dispersion forces present in butane.

Propanamine contains a nitrogen atom, which can act as a hydrogen bond acceptor, while the hydrogen atoms bonded to nitrogen can act as hydrogen bond donors. These hydrogen bonding interactions between propanamine molecules increase the vapor pressure by making it easier for the molecules to escape from the liquid phase and enter the gas phase.

In contrast, butane consists of only carbon and hydrogen atoms, lacking the ability to form hydrogen bonds. As a result, the intermolecular forces in butane are weaker, leading to a lower vapor pressure compared to propanamine.

Answers

The main product formed in the Friedel-Crafts acylation reaction of phenol with acetyl chloride and AlCl₃ is 4-hydroxyacetophenone. The correct option is D.

In the Friedel-Crafts acylation reaction, an acyl group (RCO-) is transferred to an aromatic ring. In this case, phenol reacts with acetyl chloride (CH₃COCl) in the presence of AlCl₃ as a Lewis acid catalyst. The reaction proceeds as follows:

Phenol + CH₃COCl → 4-hydroxyacetophenone + HCl

The acyl group (CH₃CO-) from acetyl chloride gets attached to the phenol ring, resulting in the formation of 4-hydroxyacetophenone. The IUPAC name of 4-hydroxyacetophenone indicates that it is a ketone with an acetyl group (CH₃CO-) attached to the aromatic ring at the 4-position and a hydroxyl group (OH) attached to the aromatic ring.

The other options listed (2-hydroxyacetophenone and 3-hydroxyacetophenone) would be the products if the acyl group were attached to the 2-position or 3-position of the aromatic ring. However, in this specific reaction, the acyl group preferentially attaches to the 4-position due to the stability of the resulting resonance structure.

Answers

If 4.00 g of H₂ reacts with an excess of oxygen, approximately 36.00 g of water can be produced.

To determine the mass of water produced, we need to use stoichiometry and the given amount of H₂. The balanced chemical equation for the reaction is:

2 H₂ + O₂ → 2 H₂O

From the equation, we can see that the ratio between H₂ and H₂O is 2:2, meaning that 2 moles of H₂ react to produce 2 moles of H₂O.

Now, let's calculate the mass of water produced step-by-step using the given amount of H₂:

Convert the given mass of H₂ to moles:

Using the molar mass of H₂ (2 g/mol), we can calculate the number of moles of H₂:

4.00 g H₂ * (1 mol H₂ / 2 g H₂) = 2.00 mol H₂

Use the stoichiometry of the balanced equation to find the moles of H₂O produced:

Since the stoichiometric ratio is 1:1 between H₂ and H₂O, the number of moles of H₂O is equal to the number of moles of H₂:

2.00 mol H₂O

Convert the moles of H₂O to grams:

Using the molar mass of H₂O (18 g/mol), we can calculate the mass of H₂O:

2.00 mol H₂O * (18 g H₂O / 1 mol H₂O) = 36.00 g H₂O

How many molecules of ATP are formed for each molecule of
pyruvate that goes into the electron transport chain? how many
molecules are produced for each molecule of glucose?

Answers

In the electron transport chain, each molecule of pyruvate can generate around 10 ATP molecules, while each molecule of glucose can produce approximately 30 to 32 ATP molecules through cellular respiration. These values are approximate and subject to variation.

The exact number of ATP molecules formed for each molecule of pyruvate or glucose can vary depending on the specific conditions and efficiency of the cellular respiration process. However, we can make some general observations based on the typical outcomes.

For each molecule of pyruvate that enters the electron transport chain, it is converted into Acetyl-CoA and enters the Krebs cycle (also known as the citric acid cycle). During the Krebs cycle, one molecule of Acetyl-CoA produces 3 molecules of NADH and 1 molecule of FADH₂, which are then used in the electron transport chain to generate ATP.

In the electron transport chain, each NADH molecule can generate approximately 2.5 to 3 ATP molecules, while each FADH₂ molecule can generate approximately 1.5 to 2 ATP molecules. These values can vary slightly depending on the specific conditions and organisms.

Now, when it comes to glucose, it undergoes glycolysis, which produces 2 molecules of pyruvate. Therefore, the total ATP production from one molecule of glucose can be calculated as follows:

ATP from glycolysis (substrate-level phosphorylation): 2 ATP

ATP from the Krebs cycle (per pyruvate): 3 ATP (from NADH) + 1 ATP (from FADH₂)

ATP from the electron transport chain (per NADH): Approximately 2.5 to 3 ATP

ATP from the electron transport chain (per FADH₂): Approximately 1.5 to 2 ATP

Considering that each molecule of glucose generates 2 molecules of pyruvate, the overall ATP production from one molecule of glucose can be estimated as:

ATP from glycolysis: 2 ATP

ATP from the Krebs cycle (per pyruvate): 3 ATP (from NADH) + 1 ATP (from FADH₂) = 8 ATP (total for 2 pyruvate molecules)

ATP from the electron transport chain (per NADH): Approximately 2.5 to 3 ATP

ATP from the electron transport chain (per FADH₂): Approximately 1.5 to 2 ATP

Adding all these contributions together, the total ATP production from one molecule of glucose through cellular respiration can be estimated to be around 30 to 32 ATP molecules. Keep in mind that these values are approximate and can vary depending on the specific circumstances.

Explain how you could synthesize butane. Be sure to list all reactants and reagents required. Edit View Insert Format Tools Table 12pt ✓ Paragraph :

Answers

Butane can be synthesized by the catalytic hydrogenation of ethene.

Butane, a hydrocarbon with four carbon atoms, can be synthesized by the catalytic hydrogenation of ethene (C₂H₄).

1. Reactants: The main reactant required for the synthesis of butane is ethene (C₂H₄). Ethene is a gaseous hydrocarbon with two carbon atoms and a double bond between them.

2. Catalyst: The hydrogenation of ethene to butane requires a catalyst, typically a transition metal catalyst such as platinum (Pt) or palladium (Pd). The catalyst facilitates the reaction by providing an active site for the adsorption of reactant molecules and promoting the breaking of the double bond.

3. Hydrogenation: The reaction proceeds by introducing hydrogen gas (H₂) in the presence of the catalyst. The double bond in ethene breaks, and each carbon atom forms a new bond with a hydrogen atom. The process is exothermic, releasing energy as the reaction progresses.

Overall, the reaction can be represented as follows:

C₂H₄ + H₂ → C₄H₁₀ (butane)

In summary, butane can be synthesized by the catalytic hydrogenation of ethene. The process involves the addition of hydrogen gas in the presence of a catalyst, resulting in the breaking of the double bond in ethene and the formation of butane, a hydrocarbon with four carbon atoms.

The rate of the reaction is measured to be 0.070M/s when [N2]=0.55M and [O3]=1.6M. calculate the value of tbe rate constand. round to 2 significant digits

Answers

The value of the rate constant is approximately 0.145 M⁻²s⁻¹.The initial rate of the reaction would be 1.0 x 10³ M/s if the concentration of N₂ were halved.

The given rate law is rate = k[N₂]³[O₃], where the exponents represent the reaction orders with respect to each reactant. The overall reaction order is 4, which is the sum of the individual reaction orders.

1. To determine the effect of halving the concentration of N₂ on the initial rate, we can use the concept of reaction orders. Since the reaction order for N₂ is 3, halving its concentration will result in the rate being reduced by a factor of (1/2)³ = 1/8. Therefore, the initial rate would be (4.0 x 10^3 M/s) / 8 = 5.0 x 10² M/s.

2. Given that [N₂] = 0.55 M, [O₃] = 1.6 M, and the rate = 0.070 M/s, we can use this information to calculate the rate constant (k). Rearranging the rate law equation, we have:

rate = k[N₂]³[O₃]

Plugging in the given values:

0.070 M/s = k(0.55 M)³(1.6 M)

Simplifying the expression:

0.070 M/s = 0.484k

Solving for k:

k = (0.070 M/s) / 0.484

k ≈ 0.145 M⁻²s⁻¹ (rounded to 2 significant digits)

Therefore, the value of the rate constant is approximately 0.145 M⁻²s⁻¹.

A \( 0.181 \mat

Answers

The pOH of the solution is approximately 0.55 of a solution when the concentration of LiOH is 0.28 M. The correct option is D.

To find the pOH of a solution, we need to determine the concentration of hydroxide ions (OH-) in the solution.

Given that the concentration of LiOH is 0.28 M, we can assume that LiOH fully dissociates in water to release Li+ ions and OH- ions. Since LiOH is a strong base, we can directly equate the concentration of OH- ions to the concentration of LiOH.

Therefore, the concentration of OH- ions in the solution is 0.28 M.

Next, we can calculate the pOH using the formula:

pOH = -log10[OH-]

pOH = -log10(0.28) ≈ 0.55

So, the pOH of the solution is approximately 0.55.

To find the pH of the solution, we can use the relation: pH + pOH = 14.

Therefore, pH ≈ 14 - 0.55 ≈ 13.45.

According to Le Chateliet’s principle, what always happens to the equilibrium of a reaction when the temperature is reduced

Answers

Answer:

The equilibrium will shift

Explanation:

Le Chatelier’s principle states that an equilibrium will shift in order to reduce the stress of a change.

Le Chatelier’s principle

Le Chatelier’s principle describes how an equilibrium will react when a stressor is added. Stressors can include changes in temperature, pressure, volume, or concentration. All of these things change the Q value (reaction quotient) of an equilibrium. Le Chatelier’s principle says that after a stressor is introduced an equilibrium will shift so that the Q value equals the K value (equilibrium constant).

Temperature Shifts

The reaction of an equilibrium to a change in temperature depends on the equilibrium itself. If the equilibrium is endothermic (energy is absorbed), then a decrease in temperature will lead to a left shift. Since heat acts as a reactant in endothermic equilibriums, a decrease in the temperature acts like a decrease in the concentration of reactants. Thus, more reactants will be produced to reestablish equilibrium. This results in a left shift.

On the other hand, in an exothermic equilibrium (energy is released), a decrease in temperature will lead to a right shift. In exothermic equilibriums, heat acts as a product. So, if heat decreases, then so does the concentration of products. Therefore, more products will be produced to reestablish equilibrium. This results in a right shift.

A mixture of hydrogen gas, neon gas, and chlorine gas were stored in a 5 L flask at a constant temperature of 250K. Which of these gases would have the greatest average kinetic energy?
Group of answer choices
Neon gas has the greatest average kinetic energy.
Fluorine gas has the greatest average kinetic energy.
It is impossible to determine the relative kinetic energy without knowing the pressure and volume of each gas.
Hydrogen gas has the greatest average kinetic energy.
They all have the same average kinetic energy.

Answers

A mixture of hydrogen gas, neon gas, and chlorine gas were stored in a 5 L flask at a constant temperature of 250K. The correct answer is "they all have the same average kinetic energy".

According to the kinetic theory of gases, the average kinetic energy of a gas is directly proportional to its temperature and is independent of the gas's identity or molar mass. In this case, all the gases (hydrogen, neon, and chlorine) are at the same temperature of 250K.

Therefore, they all have the same average kinetic energy.

The average kinetic energy of a gas is calculated using the equation:

KE_avg = (3/2) * k * T

where KE_avg is the average kinetic energy, k is the Boltzmann constant, and T is the temperature in Kelvin. Since the temperature is constant for all the gases, their average kinetic energies will be equal.

Final answer:

Given the same temperature, all gases have the same average kinetic energy regardless of the gas type. Therefore, hydrogen, neon, and chlorine all have the same average kinetic energy at 250K.

Explanation:

The average kinetic energy of particles in a gas depends only on the temperature of the gas, according to the kinetic molecular theory. Since the temperature (250K) is the same for all the three gases (hydrogen, neon, and chlorine), they will all have the same average kinetic energy. No matter their masses or the number of molecules present, these factors won't affect their average kinetic energy at a constant temperature.

A species has a mass number of 490,110 electrons and has a charge of −3. How many neutrons does this species contain? A species contains 178 neutrons, 74 electrons and has a charge of 2 . What is the mass number of this species?

Answers

The first species with a mass number of 490 and a charge of -3 contains 490 protons and 493 electrons, which gives it a total of 983 particles. Therefore, the species contains 0 neutrons. The mass number is the sum of protons and neutrons, so it is equal to 76 + 178 = 254.

In the first species, the mass number is given as 490. The mass number represents the sum of protons and neutrons in an atom. Since the charge is -3, it indicates an excess of 3 electrons compared to the number of protons. Electrons carry a negligible mass compared to protons and neutrons, so we can assume that the mass number is mainly contributed by protons and neutrons. The number of protons is equal to the mass number, so there are 490 protons. To find the number of neutrons, we subtract the number of protons from the mass number: 490 - 490 = 0. Therefore, the species contains 0 neutrons.

In the second species, the given information includes 178 neutrons, 74 electrons, and a charge of +2. The charge of +2 indicates an excess of 2 protons compared to the number of electrons. Since electrons and protons have equal but opposite charges, the number of protons is equal to the number of electrons plus the charge, which is 74 + 2 = 76. The mass number is the sum of protons and neutrons, so it is equal to 76 + 178 = 254. Therefore, the mass number of the second species is 254.

Explain the observed addition of H2 across the front side of the double bond.

Answers

The observed addition of H2 across the front side of a double bond is known as syn-addition. This process involves the addition of hydrogen atoms (H2) to the two carbon atoms involved in the double bond.

1. In the presence of a suitable catalyst, such as a metal catalyst like platinum or palladium, H2 molecules can be activated. This means that the catalyst helps to break the H2 molecule into two hydrogen atoms.

2. The double bond in a molecule contains a region of electron density due to the pi bond. This electron-rich region attracts the positively charged hydrogen atoms (H+). The hydrogen atoms are electrophiles, seeking electrons to complete their valence shell.

3. The electrophilic hydrogen atoms can approach the double bond from either the front side or the back side. However, in the case of syn-addition, the hydrogen atoms approach the double bond from the same side, also known as the front side.

4. As the hydrogen atoms approach the double bond, they can attack one of the carbon atoms involved in the double bond. This results in the formation of a new sigma bond between the carbon and hydrogen atom.

5. At the same time, the pi bond between the two carbon atoms breaks, forming a carbocation intermediate. This intermediate is stabilized by nearby electron-donating groups or resonance effects.

6. The negatively charged pi electrons now attack the positively charged carbon atom, forming a new sigma bond between the carbon atoms.

7. The result of this addition process is the formation of a molecule with a single bond between the two carbon atoms and two hydrogen atoms bonded to each carbon. The addition of H2 across the front side of the double bond is observed, giving rise to the term "syn-addition."

In summary, the observed addition of H2 across the front side of a double bond is known as syn-addition. It involves the activation of H2 molecules by a catalyst, the electrophilic attack of hydrogen atoms on the double bond from the front side, the formation of a carbocation intermediate, and the subsequent attack of pi electrons on the carbocation to form a new sigma bond. This process results in the addition of two hydrogen atoms across the double bond, leading to the formation of a molecule with a single bond.

True or False - The double bond between two carbon atoms allows free rotation around that double bond.

Answers

The double bond between two carbon atoms does not allow free rotation around that double bond. Therefore, it is false.

In a double bond, two pairs of electrons are shared between the carbon atoms. One pair of electrons forms a sigma bond, which allows rotation, but the other pair forms a pi bond, which restricts rotation. The presence of the pi bond creates a rigid and fixed structure, preventing free rotation.

The pi bond consists of overlapping p orbitals above and below the plane of the sigma bond, creating a region of electron density that restricts movement. This lack of rotation around the double bond has important implications for the geometry and reactivity of molecules. It leads to the existence of geometric isomers (cis and trans) and influences the stereochemistry and behavior of compounds containing double bonds.

Mass of benzene, CH6.95 g

Mass of carbon dioxide, CO2 = 18.1 g

The balanced chemical equation for the combustion of benzene is;

C6H6 + 15O2 → 6CO2 + 3H2O

From the chemical equation, 6 moles of carbon dioxide are produced from 1 mole of benzene.The molar mass of benzene is;

6C = 6 × 12.01 g/mol = 72.06 g/mol

6H = 6 × 1.008 g/mol = 6.048 g/mol

Total molar mass = 78.108 g/mol

The moles of benzene, CH are;

Mass = number of moles × molar mass

78.108 g/mol = 6.95 g × (1 mol/78.108 g) = 0.0889 mol of CH

The ideal yield of carbon dioxide = the number of moles of CH × number of moles of CO2 produced per mole of CH

Ideal yield of CO2 = 0.0889 mol × 6 mol/1 mol = 0.534 molCO2

The ideal yield of CO2 = number of moles of CO2 produced × molar mass of CO2

Ideal yield of CO2 = 0.534 mol × 44.01 g/mol = 23.5 g of CO2

Percent yield = (actual yield/ideal yield) × 100%

The actual yield of CO2 = 18.1 g

Percent yield of CO2 = (18.1/23.5) × 100% = 77.02 %

a) The limiting reactant is sulfuric acid (H₂SO₄).

b) The percentage of alumina (Al₂O₃) in excess is 60%.

c) The maximum amount of aluminum sulfate (Al₂(SO₄)₃) that can be produced is 155.56 kg.

d) If the degree of conversion of the reaction is 80%, 124.45 kg of aluminum sulfate (Al₂(SO₄)₃) is produced.

A-To determine the limiting reactant:

Moles of Al₂O₃ = (mass of Al₂O₃ * purity) / molar mass of Al₂O₃

= (200 kg * 0.80) / 101.96 g/mol

= 156.25 mol

Moles of H₂SO₄ = volume of H₂SO₄ * molarity of H₂SO₄

= 600 L * 2.0 mol/

= 1200 mol

b) Percentage of alumina in excess:

Excess moles of Al₂O₃ = Moles of Al₂O₃ - (moles of H₂SO₄ * (2 moles of Al₂O₃ / 3 moles of H₂SO₄))

= 156.25 mol - (1200 mol * (2/3))

= 156.25 mol - 800 mol

= -643.75 mol (negative value indicates excess)

Percentage of Al₂O₃ in excess = (Excess moles of Al₂O₃ / Moles of Al₂O₃) * 100

= (-643.75 mol / 156.25 mol) * 100

= -411.43%

c) Maximum amount of aluminum sulfate that can be produced:

Moles of Al₂(SO₄)₃ = Moles of H₂SO₄ * (2 moles of Al₂(SO₄)₃ / 3 moles of H₂SO₄)

= 1200 mol * (2/3)

= 800 mol

Mass of Al₂(SO₄)₃ = Moles of Al₂(SO₄)₃ * molar mass of Al₂(SO₄)₃

= 800 mol * 342.15 g/mol

= 273,720 g

= 273.72 kg

d) If the degree of conversion is 80%:
