1. The reaction CO+2H2-CH3OH was carried and it is found that only 332g of CH3Oh is actually produced when 407g CH3Oh was the expected yield. What is the Percent yield?

2. If 112g of CaO is reactied with an excess of NH4Cl and 64.0g of NH3 are produced, what is the percent yield?
a. calculate the theoretic yield?
b. calculate percent yield?

this is the equetion for question 2

CaO+2NH4Cl-2NH3+H2O+CaCl2

Percent yield = (actual yield/theoretical yield) *100 = ?

To calculate the percent yield, we need to compare the actual yield with the theoretical yield. The actual yield is the amount of product obtained experimentally, and the theoretical yield is the calculated amount of product that should be obtained based on stoichiometry.

1. Percent Yield Calculation:
Actual yield = 332 g CH3OH
Theoretical yield = 407 g CH3OH

Percent yield = (Actual yield / Theoretical yield) * 100
Percent yield = (332 g / 407 g) * 100

To calculate percent yield for the reaction CO+2H2->CH3OH, you need the balanced equation and molar masses of the reactants and products. Once you have the molar masses, you can calculate the theoretical yield using stoichiometry. Then, divide the actual yield by the theoretical yield and multiply by 100 to get the percent yield.

2. Percent Yield Calculation:
a. Calculate Theoretical Yield:
To calculate the theoretical yield, we need the balanced equation for the reaction between CaO and NH4Cl and the molar masses of the reactants and products. The balanced equation is:

CaO + 2NH4Cl -> CaCl2 + 2NH3 + H2O

The molar mass of CaO is 56.08 g/mol, so 112 g of CaO is equal to 112 g / 56.08 g/mol = 2 mol CaO.

According to the balanced equation, 1 mol CaO reacts with 2 mol NH4Cl to produce 2 mol NH3. So, 2 mol CaO will react with 4 mol NH4Cl to produce 4 mol NH3.

The molar mass of NH3 is 17.03 g/mol, so 4 mol NH3 is equal to 4 mol x 17.03 g/mol = 68.12 g NH3.

Therefore, the theoretical yield is 68.12 g.

b. Calculate Percent Yield:
Actual yield = 64.0 g NH3
Theoretical yield = 68.12 g NH3

Percent yield = (Actual yield / Theoretical yield) * 100
Percent yield = (64.0 g / 68.12 g) * 100

To calculate the percent yield for this reaction, you need the balanced equation, the molar masses of the reactants and products, and the amount of reactant used. Using stoichiometry, you can calculate the theoretical yield. Then, divide the actual yield by the theoretical yield and multiply by 100 to get the percent yield.
