Question

Which chemical equation is balanced? OCH4 + O2 + H2O + CO2 OCH4 + O2 + 2H2O + CO2 O 6 CH4 + O2 + 2H2O + 2 CO2 OCH4 + 202 + 2H2O + CO2​

Answer 1

CH₄ + 2O₂ → 2H₂O + CO₂

Step-by-step explanation:

Chemical equation:

CH₄ + O₂ → H₂O + CO₂

Balanced chemical equation:

CH₄ + 2O₂ → 2H₂O + CO₂

Option d is correct option.

1st step:

CH₄ + O₂ → H₂O + CO₂

Left hand side Right hand side

C = 1 C = 1

H = 4 H = 2

O = 2 O = 3

Step 2:

CH₄ + O₂ → 2H₂O + CO₂

Left hand side Right hand side

C = 1 C = 1

H = 4 H = 4

O = 2 O = 4

Step 3:

CH₄ + 2O₂ → 2H₂O + CO₂

Left hand side Right hand side

C = 1 C = 1

H = 4 H = 4

O = 4 O = 4
