Which Mass Of Carbon Id Produced?

Answers

Answer 1

Answer:

(c) 4.4g

Explanation:

Given:

mass of calcium carbonate (mCaCO3) = 10g

MrCaCO3 = 100

To find: mCO2

Solution:

CaCO3 + 2HCl → CaCl 2 + H2O + CO2

Now,

MrCaCO3 = 40 + 12 + 16.3 = 100

Therefore,

Number of moles (n) = m/Mr

nCaCO3 = 10/100 = 0.1

The amount of moles is proportional to the coefficient of the reaction. Since both calcium carbonate (CaCO3) and carbon dioxide (CO2) have the same coefficient.

nCO2 = 0.1

MrCO2 = 12 + 16.2 = 44

mCO2 = 0.1 × 44 = 4.4g

What is the trend of atomic radii in a period?

The trend of atomic radii in a period (horizontal row) of the periodic table is generally a decrease from left to right. This is due to an increase in the effective nuclear charge, which is the positive charge felt by the outermost electrons in the atom. As the atomic number increases across a period, the number of protons in the nucleus increases, which increases the effective nuclear charge. This stronger attraction between the positively charged nucleus and the negatively charged electrons causes the atomic radius to decrease.

why is cooler material more dense than warmer material

Answers

Cooler materials are more dense than warmer materials because density increases as temperature decreases.

This is due to the fact that molecules slow down as the temperature drops, causing them to move closer together and increase the density of a material. This is known as the Law of Charles and Gay-Lussac, which states that the pressure of a gas is directly proportional to its temperature. As the temperature decreases, the pressure also decreases, causing the molecules to come closer together and increase the density of the material.This is due to the fact that thermal energy, which causes particles to move farther apart, is reduced when temperature decreases. As the particles become more tightly packed, the material becomes denser.

if 20.00 g of a compound reacts completely with 30.00 g of another compound in a combination reaction, how many grams of product are formed?

Answers

In a compound reaction, 80 grams of the product are created when 20 grams of one substance completely react with 30 grams of another.

Assuming we have the balanced chemical equation for the reaction, we can use stoichiometry to determine the amount of product formed.

let's say the balanced chemical equation for the reaction between the two compounds is: A + B -> C

where A and B are the two compounds and C is the product.

We can use the coefficients in the balanced equation to determine the mole ratio of A to B to C.

Let's assume that the mole ratio of A to B to C is 1:2:3.

Let's assume that the molar mass of compound A is 40 g/mol and the molar mass of compound B is 60 g/mol. Using these values, we can calculate the number of moles of each compound as:

moles of A = 20.00 g / 40 g/mol = 0.50 mol

moles of B = 30.00 g / 60 g/mol = 0.50 mol

Since the mole ratio of A to B to C is 1:2:3, we can see that 0.50 moles of A react with 1.00 mole of B to produce 1.50 moles of C.

To convert the moles of C to grams, we can use the molar mass of C. Let's assume that the molar mass of C is 80 g/mol. Using this value, we can calculate the mass of C formed as:

mass of C = 1.50 mol x 80 g/mol = 120 g

What would be the theoretical yield in moles for CO2 when there is 63.2 amount of moles of 02 present?
C+02->602

Answers

The theoretical yield of CO2 in moles when there is 63.2 moles of O2 present is 63.2 moles.

Describe Chemical Reaction?

A chemical reaction is a process in which one or more substances, called reactants, are converted into one or more different substances, called products. This process involves the breaking and forming of chemical bonds between atoms and/or molecules, resulting in a change in the chemical composition of the substances involved.

Chemical reactions can be classified into several different types based on the changes that occur during the reaction, including:

Synthesis or combination reactions: where two or more reactants combine to form a single product.

Decomposition reactions: where a single reactant breaks down into two or more products.

Single replacement or displacement reactions: where one element replaces another element in a compound, resulting in the formation of a new compound.

Double replacement or displacement reactions: where two compounds exchange ions or atoms to form two new compounds.

Acid-base reactions: where an acid and a base react to form a salt and water.

Assuming that the balanced chemical equation is:

C + O2 → CO2

We can see that the stoichiometric ratio between O2 and CO2 is 1:1. This means that for every 1 mole of O2 consumed, 1 mole of CO2 is produced. Therefore, if there are 63.2 moles of O2 present, the theoretical yield of CO2 would also be 63.2 moles.

So, the theoretical yield of CO2 in moles when there is 63.2 moles of O2 present is 63.2 moles.

You would like to determine if the temperature inside a freezer is lower than 0°C. Using a glass of liquid water, describe how you could estimate the temperature. Could you determine if the freezer has a temperature of −10°C by just using the glass of water?

Answers

Yes, you can determine if the temperature inside a freezer is below 0°C by using a glass of liquid water. Here's how:

Fill a glass with room-temperature water.Place the glass of water inside the freezer and let it sit for a few minutes, until the water has stabilized at the temperature of the freezer.Observe the state of the water. If the water is still liquid, then the temperature inside the freezer is above 0°C. If the water is beginning to freeze, with ice forming on the surface, then the temperature is below 0°C.

However, it is not possible to determine the exact temperature of the freezer by just using a glass of water. The temperature can only be estimated by observing the state of the water and making a rough guess based on the extent of the freezing.

For example, if the water is just starting to freeze, then the temperature could be close to 0°C. If the water has mostly frozen, then the temperature could be closer to -10°C. However, without a thermometer, the exact temperature cannot be determined.

The effects of a catalyst on a chemical reaction are to react with the product, effectively removing it and shifting the equilibrium to the right. The given statement is False.

The Role of Catalysts in Chemical Reactions

Catalysts are substances that can increase the rate of a chemical reaction without being consumed in the process. They work by providing an alternative pathway for the reaction to occur, with lower activation energy. This allows more reactant molecules to overcome the energy barrier and form products in a shorter amount of time. Catalysts do not change the thermodynamics of the reaction, which means that they do not affect the equilibrium position of the reaction. Therefore, they cannot shift their reaction to the right or the left, and they do not consume any of the products. Catalysts can be used in a wide range of chemical reactions, from industrial processes such as the Haber-Bosch process for ammonia synthesis to biological reactions such as enzyme-catalyzed reactions in the human body.

Explanation:

weak bases are ammonia (NH3), methylamine (CH3NH2), and ethylamine (C2H5NH2)

The term that describes the electrolyte capacity of methylamine (CH₃NH₂) which partially dissociates in water is Weak electrolyte.

Because it dissolves in water only partially into ions, methylamine (CH₃NH₂)  is a weak electrolyte. A small amount of electrical current can conduct when certain methylamine molecules split apart into ions CH₃NH₃⁺ and OH⁻ in a solution. Weak electrolytes have a moderate level of electrical conductivity compared to strong electrolytes which almost entirely dissociate into ions and non-electrolytes which do not dissociate.

Answers

the actual volume of water measured out is 10.02 ml, which is slightly higher than the intended volume of 10 ml. This could be due to various factors, such as the presence of air bubbles or human error in reading the pipet

To determine the actual volume of water measured out, we need to use the given information about the mass and density of water.

First, we can use the density formula to calculate the mass of 10 ml of water:

density = mass / volume

Rearranging the formula, we get:

mass = density x volume

Substituting the given values, we get:

mass = 0.9978 g/ml x 10 ml = 9.978 g

This means that the mass of the water measured out is 9.978 g.

However, the question states that the mass of the measured water is 9.990 g. This means that there is an additional mass of water that was inadvertently added or that there is an error in the measurement.

To find the actual volume of water measured out, we can use the following formula:

actual volume = measured mass / density

Substituting the given values, we get:

actual volume = 9.990 g / 0.9978 g/ml = 10.02 ml

Therefore, the actual volume of water measured out is 10.02 ml, which is slightly higher than the intended volume of 10 ml. This could be due to various factors, such as the presence of air bubbles or human error in reading the pipet

suppose 0.450 l of 0.450 m h2so4 is mixed with 0.400 l of 0.270 m koh . what concentration of sulfuric acid remains after neutralization?

Answers

The concentration of sulfuric acid remaining after neutralization is 0 M.

First, we need to determine the number of moles of [tex]H_{2} SO_{4}[/tex] and KOH that are present in the solution.

The number of moles of [tex]H_{2} SO_{4}[/tex] in 0.450 L of 0.450 M solution can be calculated as follows:

moles [tex]H_{2} SO_{4}[/tex] = volume of solution (L) x molarity

moles [tex]H_{2} SO_{4}[/tex] = 0.450 L x 0.450 mol/L

moles [tex]H_{2} SO_{4}[/tex] = 0.2025 mol

Similarly, the number of moles of KOH in 0.400 L of 0.270 M solution can be calculated as follows:

moles KOH = volume of solution (L) x molarity

moles KOH = 0.400 L x 0.270 mol/L

moles KOH = 0.108 mol

The balanced chemical equation for the reaction between [tex]H_{2} SO_{4}[/tex] and KOH is:

[tex]H_{2} SO_{4}[/tex] + 2KOH → [tex]K_{2} SO_{4}[/tex] + [tex]2H_{2} O[/tex]

From the equation, we can see that 1 mole of [tex]H_{2} SO_{4}[/tex] reacts with 2 moles of KOH. Since the number of moles of KOH (0.108 mol) is less than half the number of moles of [tex]H_{2} SO_{4}[/tex] (0.2025 mol), KOH is the limiting reactant.

The reaction between [tex]H_{2} SO_{4}[/tex] and KOH consumes all of the KOH and produces [tex]K_{2} SO_{4}[/tex] and [tex]H_{2} O[/tex].

The number of moles of [tex]H_{2} SO_{4}[/tex] that reacts with KOH is:

moles [tex]H_{2} SO_{4}[/tex] consumed = 2 x moles KOH

moles [tex]H_{2} SO_{4}[/tex] consumed = 2 x 0.108 mol

moles [tex]H_{2} SO_{4}[/tex] consumed = 0.216 mol

The number of moles of [tex]H_{2} SO_{4}[/tex]that remain after neutralization is:

moles [tex]H_{2} SO_{4}[/tex] remaining = initial moles [tex]H_{2} SO_{4}[/tex] - moles [tex]H_{2} SO_{4}[/tex] consumed

moles [tex]H_{2} SO_{4}[/tex] remaining = 0.2025 mol - 0.216 mol

moles [tex]H_{2} SO_{4}[/tex] remaining = -0.0135 mol

Since we cannot have a negative number of moles, this means that all of them [tex]H_{2} SO_{4}[/tex] has been consumed and there is an excess of KOH remaining.

Therefore, the concentration of sulfuric acid remaining after neutralization is 0 M.

3. What estimates of the cation–anion distance would you obtain for these four compounds using bonding atomic radii? Are these estimates as accurate as the estimates using ionic radii? Explain your answer.
Please explain the part on the 4% accuracy.

Answers

The 4% accuracy mentioned in the question was not specific to any particular measurement. It is a general assumption about the maximum amount of error that could be present in the measured ion-ion distances.

To predict the cation-anion distance using the values of ionic radii given in Figure 7.7, we can simply add the ionic radii of the cation and anion. The ionic radii for Li+, Na+, K+, and Rb+ are given in the figure as 0.76 Å, 1.02 Å, 1.38 Å, and 1.52 Å, respectively. The ionic radii for F-, Cl-, Br-, and I- are given as 1.19 Å, 1.81 Å, 1.96 Å, and 2.20 Å, respectively. Adding the appropriate cation and anion radii gives the following predicted cation-anion distances:

LiF: 0.76 Å + 1.19 Å = 1.95 Å

NaCl: 1.02 Å + 1.81 Å = 2.83 Å

KBr: 1.38 Å + 1.96 Å = 3.34 Å

RbI: 1.52 Å + 2.20 Å = 3.72 Å

To calculate the difference between the experimentally measured ion-ion distances and the ones predicted, we can subtract the predicted distance from the measured distance. The differences are:

LiF: 2.01 Å - 1.95 Å = 0.06 Å

NaCl: 2.82 Å - 2.83 Å = -0.01 Å

KBr: 3.30 Å - 3.34 Å = -0.04 Å

RbI: 3.67 Å - 3.72 Å = -0.05 Å

Assuming an accuracy of 0.04 Å in the measurement, we can say that the LiF and KBr values are within the margin of error, while the NaCl and RbI values are outside the margin of error. However, it is important to note that these differences are relatively small and may be attributed to experimental error.

Bonding atomic radii are typically used to estimate the size of the atom that forms a covalent bond. To estimate the cation-anion distance using bonding atomic radii, we can add the bonding atomic radii of the cation and anion. The bonding atomic radii for Li, Na, K, and Rb are 1.28 Å, 1.54 Å, 1.96 Å, and 2.11 Å, respectively. The bonding atomic radii for F, Cl, Br, and I are 0.71 Å, 0.99 Å, 1.14 Å, and 1.33 Å, respectively. Adding the appropriate cation and anion radii gives the following estimated cation-anion distances:

LiF: 1.28 Å + 0.71 Å = 1.99 Å

NaCl: 1.54 Å + 0.99 Å = 2.53 Å

KBr: 1.96 Å + 1.14 Å = 3.10 Å

RbI: 2.11 Å + 1.33 Å = 3.44 Å

In one mole of sodium carbonate, there are 2 moles of sodium , 6 moles of oxygen and 1 mole of C. Hence, in 1.25 moles of the compound, 2.5 moles of Na, 7.5 moles of O and 1.25 moles of C.

What is molar mass ?

The molar mass of a compound  is the mass of one mole of the compound. One mole of any compound contains 6.02 × 10²³ atoms. This number is called Avogadro number.

2.  Convert 2.50 mol of Na2CO3 to mass in g.

Molar mass of sodium carbonate  = 106 g/mol

then, mass of 2.50 mol = 265 g.

3. Convert 5.50 g of Na2CO3 to mol.

Number of moles in 5.50 g of sodium carbonate = 5.50 g/ 106 = 0.051 moles.

4.Covert 5.50 g of Na2CO3 to number of particles

Now, one mole of sodium carbonate contains Avogadro number of atoms or molecules . Then number of particles in 5.50 g that is 0.051 moles is:

0.051 × 6.022 × 10²³ = 3.072 × 10²² particles.

how many moles of barium are in a 25.0 g sample of barium? your answer should have three significant figures.

Answers

1 mole is equal to 6.023 × 10 ²³ molecules. 0.182 moles of barium are in a 25.0 g sample of barium.

What do you mean by mole ?

The term mole is defined as the amount of substance of a system which contains as many elementary entities.

One mole of any substance is equal to 6.023 × 10²³ units of that substance such as atoms, molecules, or ions. The number 6.023 × 10²³ is called as Avogadro's number or Avogadro's constant.

The mole concept can be used to convert between mass and number of particles.

I mole of any molecule = 6.023 × 10 ²³

1 mole of barium = 137.328g

To calculate moles, divide mass by molar mass yields number of moles.

25.0g barium × 1mol barium 137.328g barium

= 0.182mol barium

Thus, 0.182 moles of barium are in a 25.0 g sample of barium.

A sample of what was thought to be gold was removed from a mine in San Francisco during the gold rush. After analysis, it was determined that it was actually fool's gold, or pyrite. The sample contained 17.6 grams of iron and 103 grams of sulfur. What is the percentage composition of each element in pyrite?

Answers

Answer:

14.594% Iron and 85.406% Sulfur

Explanation:

103g (S) + 17.6g (Fe) = 120.6g total mass

103/120.6 × 100 = 85.406% Sulfur

17.6/120.6 × 100 = 14.594% Iron

write a net ionic equation for the overall reaction that occurs when aqueous solutions of sodium hydroxide and phosphoric acid (h3po4) are combined.

Answers

A net ionic equation describing the total reaction between sodium hydroxide and phosphoric acid (h3po4) in aqueous solutions.

H3PO4(aq) → Na3PO4(aq) + 3H2O(l)

To write the net ionic equation, we need to first write the balanced ionic equation, which shows all the ions in solution that participate in the reaction. The ionic equation for the reaction is:

3Na+(aq) + 3OH-(aq) + H3PO4(aq) → Na3PO4(aq) + 3H2O(l)

Next, we cancel out the spectator ions, which are the ions that appear on both sides of the equation and do not participate in the reaction. In this case, the spectator ions are the sodium ions (Na+) and the hydroxide ions (OH-). The net ionic equation is then:

H3PO4(aq) → Na3PO4(aq) + 3H2O(l)

This equation shows the actual chemical change that occurs in the reaction, which is the transfer of a proton (H+) from the phosphoric acid to the hydroxide ion, forming water and the phosphate ion.

. what does this indicate about the temperature of the hydrogen gas as compared to the measured temperature of the beaker of water? would this error cause r to be overestimated, underestimated or remain unaffected? explain your reasoning.

Answers

If the temperature of the gas is underestimated, the value of the ideal gas constant (R) will be overestimated because R is inversely proportional to the temperature.

The ideal gas law describes the behavior of gases under certain conditions, assuming that they behave as an ideal gas. The equation relates the pressure, volume, temperature, and number of moles of a gas, and is written as PV = nRT, where P is the pressure of the gas, V is its volume, n is the number of moles of gas, T is the temperature, and R is the ideal gas constant.

The ideal gas constant, R, is a proportionality constant that relates the physical properties of the gas to its behavior as an ideal gas. The value of R depends on the units used for pressure, volume, and temperature, and it can be calculated using the equation R = PV/nT.

The value of R is inversely proportional to the temperature of the gas. This means that as the temperature of the gas decreases, the value of R increases, and vice versa. Therefore, if the temperature of the gas is underestimated, the calculated value of R will be higher than it should be. This can lead to errors in other variables that are calculated using the ideal gas law, such as the pressure, volume, or number of moles of gas.

It's important to note that the ideal gas law is only an approximation, and it may not accurately describe the behavior of real gases under all conditions. However, the ideal gas law is a useful tool for understanding the behavior of gases, and it can be used to make predictions about the behavior of gases in various situations, as long as the conditions are close enough to those of an ideal gas.
