Answer 2

Answer:

When magnesium ribbon is burnt in air, a white solid, magnesium oxide is formed. The mass of magnesium is more than the mass of magnesium oxide. This is because the mass of oxygen used is not taken. If that is considered, the total mass of the reactants and the products are found to be almost equal.

2Mg + O2 → 2MgO

(Magnesium) (Air) (Magnesium oxide)
