Answer :
Final answer:
The balanced chemical equation for the combustion of methane is: CH4 + 2O2 -> CO2 + 2H2O. This equation is balanced because the number of atoms of each element is equal on both sides of the equation.
Explanation:
The question is about balancing chemical equations, specifically for the combustion of methane. One molecule of methane (CH4) combines with two molecules of diatomic oxygen (O2) to form one molecule of carbon dioxide (CO2) and two molecules of water (H2O). Thus, the balanced chemical equation is: CH4 + 2O2 -> CO2 + 2H2O.
Balancing a chemical equation involves ensuring that the number of atoms of each element is equal on both the reactant and product sides of the equation. In this case, we have 1 carbon, 4 hydrogen, and 4 oxygen atoms on both sides, so the equation is balanced.
