Answer:
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
