Answer:
Metals react with oxygen to form metal oxides.These metal oxides are basic in nature.
Metal + Oxygen ————>Metal Oxide
1)When magnesium burns in air,it combines with the oxygen of air to form magnesium oxide(basic oxide)
Magnesium +oxygen ——–> Magnesium Oxide
2 Mg(s) + O2 (g) —–> 2MgO(s)
Magnesium oxide dissolves in water to form magnesium hydroxide solution.
MgO + H20 —–> Mg(OH)2
Magnesium hydroxide turns red litmus to blue which shows that magnesium oxide is a basic oxide.
