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.
(c) Barium chloride reacts with aluminium sulphate to give aluminium chloride
and a precipitate of barium sulphate.
(d) Potassium metal reacts with water to give potassium hydroxide and hydrogen
gas.​

Answer 1

Answer:

(a)... 3H2(g) + N2(g) ——> 2NH3(g)

(b)... 2H2S(g) + 3O2(g) ——> 2H2O(l) + 2SO2(g)

(c).... 3BaCl2(aq)+ Al2(SO4)3(aq) ——> 2AlCl3(aq) + 3BaSO4(s)

(d).... 2K(s) + 2H2O(l) ——> 2KOH(aq) + H2( g)

hope it helps you....

Answer 2

Answer:

• H2 + N2 = NH3

3h2 + N2 = 2NH3

• H2S + O2 = H2O + So2

2H2S + 2O2 = 2H20 + 2So2

• Bacl2 + al(so4)3 = Alcl3 + BaSo4

3Bacl2 + al2(so4)3 = 2Alcl3 + 3Baso4

• K + H2o = KOH + H2

2K + 2H20 = 2KOH +H2
