Question

Responses

CH4+O2→CO2+H2O

CH4+O2→C+2H2O

CH+O2→CO2+H2O

CH4+O2→CO2+HO

Answer 1

The equation that demonstrates the Law of Conservation of Mass is:

CH4 + O2 → CO2 + H2O

This equation shows that the number of atoms of each element is the same on both sides. In this reaction, one molecule of methane (CH4) reacts with two molecules of oxygen (O2) to produce one molecule of carbon dioxide (CO2) and two molecules of water (H2O), thereby conserving mass.
