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 nitrogen gas is produced by the reaction of 9 gr of ammonium perchlorate? Round your answer to significant digits.

Respuesta :

Answer:

1.08 grams of nitrogen

Explanation:

Thermally ammonium perchlorate dissociate as shown in figure.

Thus as per equation two moles of ammonium perchlorate will give four moles of water, two moles of oxygen, one mole of chlorine and one mole of nitrogen,

The molar mass of ammonium perchlorate = 117.5g/mol

Two moles of ammonium perchlorate = 2X  117.5 = 234 g

The molar mass of nitrogen = 28g

thus 234 grams of ammonium perchlorate will give 28 grams of nitrogen

Hence 9 grams of ammonium perchlorate will give 1.08 grams of nitrogen
