Ammonium perchlorate is a powerful solid rocket fuel, used in the Space Shuttle boosters. It decomposes into nitrogen gas, chlorine gas, oxygen gas and water vapor, releasing a great deal of energy. Calculate the moles of ammonium perchlorate needed to produce of chlorine. Be sure your answer has a unit symbol, if necessary, and round it to significant digits.

0.18 mol

There is some info missing. I think this is the original question.

Ammonium perchlorate is a powerful solid rocket fuel, used in the Space Shuttle boosters. It decomposes into nitrogen gas, chlorine gas, oxygen gas and water vapor, releasing a great deal of energy. Calculate the moles of ammonium perchlorate needed to produce 0.090 mol of chlorine. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits.

First, we write the balanced chemical equation.

2 NH₄ClO₄(s) → N₂(g) + Cl₂(g) + 2 O₂(g) + 4 H₂O(g)

The molar ratio of NH₄ClO₄ to Cl₂ is 2:1. The moles of NH₄ClO₄ required to produce 0.090 mol of Cl₂ are:

0.090 mol Cl₂ × (2 mol NH₄ClO₄/1 mol Cl₂) = 0.18 mol NH₄ClO₄

explanation:

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
