Question

9 Given the balanced equation representing the reaction between methane and oxygen:CH4 + 2O2 → CO2 + 2H2O

According to this equation, what is the mole ratio of oxygen to methane?

Answer 1

The mole ration of two productions depends on the balanced equation which we can get from the question. And the mole ratio is equals to the ratio of number before the compounds. So the answer is 2:1.
