1. No, digestion of food is not a combustion reaction. Combustion reactions involve a substance reacting with oxygen to produce heat and light. While digestion does involve breaking down substances (food) into simpler forms, it does not involve a reaction with oxygen, nor does it produce heat and light. Instead, digestion involves enzymatic reactions that break down food into nutrients that can be absorbed by the body.

2. When magnesium ribbon is burnt, it reacts with oxygen in the air to form magnesium oxide. The chemical reaction can be written as follows:

2Mg(s) + O2(g) - 2MgO(s)

This means that two atoms of solid magnesium react with one molecule of oxygen gas to produce two molecules of solid magnesium oxide.
