Consider the following reaction: CH4(g) + 2O2(g) ↓ CO2 (g) + 2H2O(g) One molecule of methane (CH4) reacts with two molecules of oxygen to form one molecule of carbon dioxide and two molecules of water.

Question

1. If 36 water molecules are formed from the above reaction, how many methane molecules reacted?
2. If 54 water molecules are formed by the above reaction, how many carbon dioxide molecules formed?

Answer 1

CH4 : H2O = 1:2
CO2 : H2O = 1:2
