CH4 (g) + O2 (g) -> CO2 (g) + H20 (g)

CH4(g) + 2O2(g) -> CO2 + 2H2O

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

the answer is b & c i believe : )

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
