Question

Balance this equation. If a coefficient of "1" is required, choose "blank" for that box.

____ CH 4 + ___ O 2 → ____ CO 2 + ____ H 2 O

Answer 1

CH4 + 2O2 → CO2 + 2H2O

Step-by-step 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

Answer 2

1 CH 4 + 2 O2 = 1 CO2 + 2 H2O
