Question

Ammonium perchlorate is the solid rocket fuel used by the U.S. Space Shuttle. It reacts with itself to produce nitrogen gas , chlorine gas , oxygen gas , water , and a great deal of energy. What mass of oxygen gas is produced by the reaction of of ammonium perchlorate

Answer 1

Answer:

2.9 g

Explanation:

The computation of the mass of oxygen gas produced is shown below:

As we know that

$2NH_4ClO_4 \rightarrow N_2 + Cl_2 + 2O_2 + 4H_2O$

Now

The $NH_4ClO_4$ presented in 9.6g = 9.6 g/117.49 g/mol  

And, the mole ratio between the $NH_4ClO_4 : H_2O$ is 1 : 2

The moles of $H_2O$ produced is 2 × 9.6 g/117.49 g/mol

So,

Mass of H2O produced is

= 18.015 g/mol × 2 × 9.6 g/117.49 g/mol

= 2.94 g
