Ammonia gas can be prepared by the reaction CaO ( s ) + 2 NH 4 Cl ( s ) ⟶ 2 NH 3 ( g ) + H 2 O ( g ) + CaCl 2 ( s ) In an experiment, 27.6 g of ammonia gas, NH 3 , is produced when it was predicted that 50.2 g NH 3 would form.

The given question is incomplete. The complete question is ;

Ammonia gas can be prepared by the following reaction:

In an experiment, 27.6 g of ammonia gas, , is produced when it was predicted that 50.2 g of would form.

What is the theoretical yield of ? What is the actual yeild of ? What is the percent yeild of ?

a) 50.2 g

b) 27.6 g

c) 5.0 %

Explanation:

a) Theoretical yield is defined as the amount of the product that is possible in the reaction.

Theoretical yield of = 50.2 g

b) Experimental or actual yield is defined as the amount of the product that is actually formed in the reaction.

Experimental yield of = 27.6 g

c) Percentage yield is defined as the ratio of experimental yileld to the theoretical yield in terms of percentage.

Hence percentage yield for the reaction is 55.0 %.

that's what i got you can count the number of atoms

elements make up everything, and they combine to make compounds.

the answer is c
