Balance this equation. If a coefficient of "1" is required, choose "blank" for that box. CH 4 + ___ O 2 → CO 2 + H 2 O

CH4 + 2O2 → CO2 + 2H2O

Explanation:

CH4 + O2 → CO2 + H2O

Left Side

C = 1

H = 4

O = 2

Right Side

C = 1

H = 2

O = 3

Ok so we'll balance the H first

CH4 + O2 → CO2 + 2H2O

Left Side

C = 1

H = 4

O = 2

Right Side

C = 1

H = 4

O = 4

Now we'll balance the O

CH4 + 2O2 → CO2 + 2H2O

Left Side

C = 1

H = 4

O = 4

Right Side

C = 1

H = 4

O = 4

h let me think
