Answer:

4

Explanation:

Since there are 3 carbons on the left side, make the coefficient of CO2 equal to 3.

Also, since there are 8 hydrogen on the left side, make the coefficient of H2O equal to 4.

This means there are 3(2)+4=10 oxygen atoms on the right, making the coefficient of O2 equal to 5.
