A CH4 + O2 -> CO2 + H2O
B CH4 + 2O2 -> CO2 + 2H2O
C 2CH4 + 3O2 -> 2CO2 + 4H2O
D CH4 + 2O2 -> CO + 2H2O

Show answer and explanation

Answer: B. CH4 + 2O2 -> CO2 + 2H2O

A balanced equation has the same number of atoms of each element on both sides. CH4 + 2O2 -> CO2 + 2H2O has 1 C, 4 H and 4 O on each side.
