Balance the following equation: C3H8 + O2 ----> CO2 + H2O. (There will be no need for state symbols.)

Carbon: 3 Carbon: 1

Hydrogen: 8 Hydrogen: 2

Oxygen: 2 Oxygen: 3

The first step would be to balance out the carbons on the products side by multiplying CO2 by 3. The new equation will be

C3H8 + 02 ----> 3CO2 + H20

Now, the carbons are balanced,
