Answer:
CH4(g) + 2O2(g) -> CO2 + 2H2O
Step-by-step explanation:
Im not sure what the question is but this is the balanced equation.
In the beggingin, there were:
1 C on each side
4 H on the reactants and 2 H on the products
2 O on the reactants and 3 O on the products.
Multiplying the H on the products side by 2 evened out the Hs but the Os became 4 on the products side and 2 on the reactants side so Multiply the O on the products side by 2 evens out the reactans and the products resulting in:
1 C on each side
4 H on each side
4 O on each side
