Answer:

CH₄ + 2O₂ –> CO₂ + 2H₂O

The coefficients are: 1, 2, 1, 2

Explanation:

CH₄ + O₂ –> CO₂ + H₂O

The above equation can be balance by as follow:

CH₄ + O₂ –> CO₂ + H₂O

There are 4 atoms of H on the left side and 2 atoms on the right side. It can be balance by writing 2 before H₂O as shown below:

CH₄ + O₂ –> CO₂ + 2H₂O

There are 2 atoms of O on the left side and a total of 4 atoms on the right side. It can be balance by writing 2 before O₂ as shown below:

CH₄ + 2O₂ –> CO₂ + 2H₂O

Now, the equation is balanced.

The coefficients are: 1, 2, 1, 2
