Fill in the coefficients that will balance the following reaction: (Note: Use 1 as coefficient where appropriate.)

CH4 +
O2 →
CO2 +
H2O

CH4 + 2 O2 → CO2 + 2 H2O

Explanation:

There are one mole of O2 on the left side and on the right side there are three moles of O2. And to fix it you would need to make it two moles of O2 to have four molecules of O2 on the left side. Then you would make two moles of H2O to have a total of four moles of O2 on the right. Therefore, CH4 + 2 O2 → CO2 + 2 H2O is the answer.

answer; /// i do believe that the correct answer is (a) boiling
