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?

Round your answer to significant digits.

Ammonium perchlorate (NH4ClO4) is the solid rocket fuel used by the U.S. Space Shuttle. It reacts with itself to produce nitrogen gas (N2), chlorine gas (Cl2), oxygen gas (O2), water (H2O), and a great deal of energy. What mass of water is produced by the reaction of 9.15 g of ammonium perchlorate?

Explanation / Answer

molar mass of ammonium percholorate=14+4+35.5+16*4

=117.5

so number of moles of NH4ClO4=7.61/117.5

=0.064 moles

2 NH4ClO4 ? Cl2 + N2 + 2 O2 + 4 H2O

so moles of O2=moles of perchlorate

=0.064

so mass of oxygen=32*0.064

=2.07 grams
