The question is incomplete , complete question is :
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 chlorine produced by the reaction of 2.5 mol of ammonium perchlorate. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits.
Answer:
1.2 moles of chlorine produced by the reaction 2.5 moles of ammonium perchlorate.
Explanation:
Moles of ammonium perchlorate = 2.5 moles
According to reaction, 2 moles of ammonium perchlorate on decomposition gives 1 mole of chlorine gas, then 2.5 moles of ammonium perchlorate wil give:
of chlorine gas
1.2 moles of chlorine produced by the reaction 2.5 moles of ammonium perchlorate.

Reaction of sodium metal with water is a chemical change . Sodium reacts with water to form sodium hydroxide. This is also an example of exothermic reaction as heat is released in this process. Sodium reacts vigoursly with water , it even reacts with the moisture present in the air . So it is stored in kerosene oil .
The reaction of sodium with water is :-
