Question

Ammonium perchlorate NH4ClO4 is a powerful solid rocket fuel, used in the Space Shuttle boosters. It decomposes into nitrogen N2 gas, chlorine Cl2 gas, oxygen O2 gas and water vapor, releasing a great deal of energy. Calculate the moles of oxygen produced by the reaction of 0.055mol of ammonium perchlorate. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

Answer 1

Answer: 0.055 moles of $O_2$ are produced by the reaction of 0.055 mol of ammonium perchlorate.

Explanation:

The balanced chemical reaction for decomposition of ammonium perchlorate is:

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

According to stoichiometry :

2 moles of $NH_4ClO_4$ produce = 2 moles of $O_2$

Thus 0.055 moles of $NH_4ClO_4$ will produce =$\frac{2}{2}\times 0.055=0.055moles$ of $O_2$

Thus 0.055 moles of $O_2$ are produced by the reaction of 0.055mol of ammonium perchlorate.
