Carbon dioxide can be made to react with hydrogen gas to produce methane and water vapour, here is an example.

CO₂ + H₂ --> CH₄ + H₂O

CO₂ + 3H₂ --> CH₄ + H₂O

CO₂ + 3 H₂ --> CH₄ + 2H₂O

CO₂ + H₂ --> CH₄ + H₂O

CO₂ + H₂ --> CH₄ + 2H₂O

CO₂ + 4H₂ --> CH₄ + 2 H₂O

Now the equation is balanced because every element has equal subscripts, so there is the same amount on the both sides.
