Question

Write equations for the following reactions:
(a) Aluminium and dilute hydrochloric acid
(b) Zinc and sodium hydroxide solution
(c) Sulphur and concentrated nitric acid (d) Sulphur dioxide gas and water
(e) Heated iron and steam.​

Answer 1

Explanation:

1.Aluminum reacts with hydrochloric acid to produce aluminum chloride and hydrogen gas. ... The equation is: 2Al+6HCl→2AlCl3+3H2 2 A l + 6 H C l → 2 A l C l 3 + 3 H 2 .

Answer 2

Answer:

Explanation:

a) aluminium and hydrochloric acid will react with each other and form

aluminium chloride + hydrogen

b) NO reaction as zinc cannot displace sodium ( because zinc is less reactive than sodium)

c) sulphur and nitric acid will react and form

sulphuric acid + nitrogen dioxide + water

d) sulphur dioxide wil react with oxygen to make

sulphur trioxide

e) heated iron reacts with steam to form

iron oxide + hydrogen
