Antoine Lavoisier developed the theory of combustion as a chemical reaction with oxygen.
As seen from the equation CH4 + 2O2 → CO2 + 2 H2O, a coefficient of 2 must be placed before the oxygen gas on the reactants side and before the water on the products side so that, as per the law of conservation of mass, the quantity of each element does not change during the reaction.
Sodium chloride is formed through the redox reaction of sodium metal and chlorine gas
