HOW MASS IS CONSERVED

 

Let’s consider a simple chemical reaction involving the combustion of methane (CH₄) in oxygen (O₂) to produce carbon dioxide (CO₂) and water (H₂O). The balanced chemical equation for this reaction is:${\text{CH}}_4(g)+2{\text{O}}_2(g)\to {\text{CO}}_2(g)+2{\text{H}}_2\text{O}(g)$Methane + Oxygen → Carbon Dioxide + Water
