Expert Answer:

When magnesium is burnt in the presence of oxygen, it produces magnesium oxide along with light and heat.Hence, it is an exothermic process.We can conclude that it is an exothermic process by taking account of following point.The product formed that is magnesium oxide is very stable when it is lower in energy than the reactant.It is a combustion reaction which is always an exothermic reaction.
