Question

The following equation shows the correct molecules formed in the reaction, but the products are incorrect. CH4 +2O2 → H2O + CO2 How would you correct the products? Explain your reasoning

Answer 1

Because the hydrogen will also be combusted in the reactions, so in this case the answer will be:

CH4+2O2-CO2+2H2O

Answer 2

Answer:

The reactants have four hydrogen atoms and four oxygen atoms. On the other hand, the products have just two hydrogen atoms and three oxygen atoms. So, to balance the chemical equation, there should be two more hydrogen atoms and one more oxygen atom. This imbalance can be corrected by placing the number 2 in front of H2O on the reactants' side.
