Answer:
a) Hydrogen gas combines with nitrogen to form ammonia.
H2(g)+N2(g)→NH3
The balanced equation for this reaction can be written as:
3H2(g)+N2(g)→2NH3
(b) Hydrogen sulphide gas burns in air to give water and sulphur dioxide.
H2S(g)+O2(g)→H2O+SO2
The balanced equation for this reaction can be written as:
2H2S(g)+3O2(g)→2H2O+2SO2
(c) Barium chloride reacts with aluminium sulphate to give aluminium chloride and a precipitate of barium sulphate.
BaCl2+Al2(SO4)3→AlCl3+BaSO4↓
The balanced equation for this reaction can be written as:
3BaCl2+Al2(SO4)3→2AlCl3+3BaSO4↓
(d) Potassium metal reacts with water to give potassium hydroxide and hydrogen gas.
