Question

5. Translate the following statements into chemical equations and then balance them.
(a) Hydrogen gas combines with nitrogen to form ammonia.
(b) Hydrogen sulphide gas burns in air to give water and sulpur dioxide.
(a) Barium chloride reacts with aluminium sulphate to give aluminium chloride
and a precipitate of barium sulphate.
(a) Potassium metal reacts with water to give potassium hydroxide and hydrogen
gas.​

Answer 1

Explanation:

(a) N2 + 3H2 ->2NH3

(b) 2H2S +3O2 -> 2SO2 + 2H2O

(c) 3BaCl2 + 2Al(SO4)3-> 2AlCl3 + 3BaSO4

(d) 2K+ 2H2O-> 2KOH+ H2

Answer 2

Explanation:

(A)hydrogen + nitrogen gives ammonia

3H2 +N2 gives 2NH3

b) 2H2S + 3O2 gives 2H2O + 2SO2

c) barium chloride + aluminium suphate = aluminium chloride + barium sulfate

Ans:

3BaCL2 + Al2(SO4)3 = 2AlCl3 + 3BaSO4

d) potassium + water = potassium hydroxide + hydrogen

ans:

2k + 2H2O = 2KOH + H2
