Detailed explanation-1: -In the given reaction, methane reacts with oxygen to form water and carbon dioxide along with heat and light. Therefore, this reaction is considered a combustion reaction.
Detailed explanation-2: -The given reaction is a combination reaction because carbon and oxygen atoms are combining to form carbon dioxide molecule as a single product.
Detailed explanation-3: -It is a combination reaction as carbon combines with oxygen to form carbon dioxide. It is a combustion reaction as carbon is burnt in the presence of oxygen.
Detailed explanation-4: -The reaction typically gives off heat and light as well. The general equation for a complete combustion reaction is: Fuel + O2 → CO2 + H2O. The burning of charcoal is a combustion reaction.
