The buffer that is adjusted to control acid-base balance is referred to as a bicarbonate buffer.

This consists of a weak acid and its conjugate base, or vice versa and resist changes in the pH of the solution.

The bicarbonate buffer is involved in acid-base homeostasis by removing CO2 and hydrogen ions, respectively, from the body.

The major product of the given chemical reaction is given as drawn in the attached picture.

A major product in chemistry refers to the product whose amount is the greatest after a chemical reaction has taken place.

In order to find the major product, it is required for the Markovnikov Rule to be applied.

This rule states that when hydrogen is mixed with carbon with more hydrogen, then the major product will be gotten.

The structural formula are similar to molecular formulas but show how atoms are bonded together.

Explanation:

The structural formula for a compound gives the same information as its molecular formula (the types and numbers of atoms in the molecule) but also shows how the atoms are connected in the molecule.

The solubility of the gas if the pressure is changed to 100 kPa is 0.742 g/L

As the pressure of a gas increases, the solubility increases, and as the pressure of a gas decreases, the solubility decreases.

Thus, Solubility varies directly with Pressure

If S represents Solubility and P represents Pressure,

Then we can write that

S ∝ P

Introducing proportionality constant, k

S = kP

S/P = k

∴ We can write that

[tex]\frac{S_{1} }{P_{1} } = \frac{S_{2} }{P_{2} }[/tex]

Where [tex]S_{1}[/tex] is the initial solubility

[tex]P_{1}[/tex] is the initial pressure

[tex]S_{2}[/tex] is the final solubility

[tex]P_{2}[/tex] is the final pressure

From the given information

[tex]S_{1} = 0.890 \ g/L[/tex]

[tex]P_{1} = 120 \ kPa[/tex]

[tex]P_{2} = 100 \ kPa[/tex]

Putting the parameters into the formula, we get

[tex]\frac{0.890}{120}=\frac{S_{2}}{100}[/tex]

[tex]S_{2}= \frac{0.890 \times 100}{120}[/tex]

[tex]S_{2}= 0.742 \ g/L[/tex]

Hence, the solubility of the gas if the pressure is changed to 100 kPa is 0.742 g/L

According to Avogadro's law equal volume of all gases at the same temperature and pressure contain equal number of molecules. At STP one mole of any gas behaving ideally occupies a volume of 22.414 L.

The volume occupied by one mole of a substance at a given temperature and pressure is defined as the molar volume at that temperature and pressure. The value of molar volume of an ideal gas at STP is important in stoichiometric calculations.

At STP, the number of molecules of a gas is given as:

Number of molecules of a gas (N) = V₀ in L /  22.414 × 6.022 × 10²³

Here  V₀ in L = 16500 = 16.5 L

N =  16.5 / 22.414  × 6.022 × 10²³

N = 4.433 × 10²³

Thus the number of molecules present is 4.432 × 10²³.

Charles' law states as follow:

V₁ / T₁ = V₂ / T₂

Where

From the question given above, the following data were obtained

V₁ / T₁ = V₂ / T₂

1.25 / 300 = V₂ / 200

Cross multiply

300 × V₂ = 1.25 × 200

Divide both side by 300

V₂ = (1.25 × 200) / 300

V₂ = 0.83 L

Answer:

3.33 moles

Explanation:

We know that our limiting reactant is chlorine so we just have to figure out how much of the product aluminum chloride (AlCl3) would be formed from 5 moles of chlorine gas. As we can see in the balanced equation, the mole ratio of chlorine gas (Cl2) to aluminum chloride is 3:2 based on the coefficients of the species. All you have to do from here is divide the amount of moles of chlorine gas by its own coefficient and then multiply the number you receive by the coefficient of AlCl3.

5/3=1.66

1.66*2=3.33

When the pressure of a gas is decreased from 3.40 atm to 2.60 atm, the temperature of the gas will decrease from 60.0 degree celsius to 45.88 degree celsius.

Gay -Lussac law states that the pressure and temperature is in direct proportions. Thus, pressure increases with an increase in temperature. The relation can be mathematically expressed as follows:

P/T = a constant. Hence,

P1/T1 = P2/T2

The initial pressure of the sample is given, 3.46 atm and the initial temperature is 60 °C. The final temperature of the gas when gas the expand to the lower pressure of 2.60 atm is calculated as follows:

[tex]T_{2} = \frac{P_{2}T_{1}}{P_{1}}[/tex]

    = (60 °C× 2.60 atm) / 3.40 atm

    = 45.88 °C.

Hence, the final temperature of the gas which is expanded from the pressure of 3.40 atm to 2.60 atm with an initial temperature of 60 °C is  45.88  °C.

The pressure in a 8.00 L tank with 50.5 grams of chlorine gas at 365 K is 2.67atm.

The pressure of a given mass of gas can be calculated using the following formula:

PV = nRT

Where;

The number of moles in 50.5g of Chlorine gas is as follows:

moles = 50.5/70.91

moles = 0.71mol

P × 8 = 0.71 × 0.0821 × 365

8P = 21..34

P = 21.34/8

P = 2.67atm

Therefore, the pressure in a 8.00 L tank with 50.5 grams of chlorine gas at 365 K is 2.67atm.
