Question

Show the formation of Na2O, CaCl2 and MgO.

Answer 1

Answer:

Formation as well as explanation given in the image.

Answer 2

Answer:

(i) Na2O

Sodium oxide is a chemical compound that is mainly used in the manufacture of glasses and ceramics.

Sodium oxide is produced by reacting sodium with sodium hydroxide.

2 NaOH + 2Na → 2Na2O + H2

(ii) CaCl2

Calcium chloride is a chemical compound that is mainly used in water treatment plants and food preservation.

Calcium chloride is mainly prepared by reacting limestone with hydrochloric acid

CaCO3 + 2HCl → CaCl2 + CO2 + H2O

(iii) MgO

Magnesium oxide is mainly used in antacid and furnace lining.

Magnesium oxide is prepared by reacting magnesium with carbon dioxide

Mg + CO2 → 2MgO + C
