 gas and water vapor, releasing a great deal of energy. Calculate the moles of ammonium perchlorate needed to produce 0.070

mol

 of nitrogen. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

Answer 1

2NH4CLO4 ----> N2 + Cl2 + O2 + 2H2O

Mole ratio = 2:1

If 0.070 moles of nitrogen are formed then 0.14 moles of ammonium perchlorate react
