Question

Write a chemical reaction of the following :-
(a) Hydrogen + Chlorine gives Hydrogen chloride
(b) Magnesium + Hydrochloric acid gives Magnesium chloride + Hydrogen
(c) Zinc + Copper sulphate gives Zinc sulphate + Coppee

Answer 1

a) H₂+Cl₂------------->2HCl

b) Mg + 2HCl-----------------------> MgCl₂+H₂

c) Zn + CuSO₄-------------->ZnSO₄ + Cu

Mark it as the brainliest plzzz.

Answer 2

The Following Chemical Reactions :

1) H² + Cl² = 2HCl

Hydrogen chloride, (HCl), a compound of the elements hydrogen and chlorine, a gas at room temperature and pressure. A solution of the gas in water is called hydrochloric acid.

2) Mg + 2HCl = MgCl² + H²

Hydrogen chloride, (HCl), a compound of the elements hydrogen and chlorine, a gas at room temperature and pressure. A solution of the gas in water is called hydrochloric acid.

3) Zn + CuSO⁴ = ZnSO⁴ + Cu

Displacement Reaction occurs as Zinc sulphate is formed and Cu gets displaced.
