b) Aluminium + copper chloride → Aluminum chloride + Copper. C) Hydrogen + Chlorine. → Hydrogen chloride. d) Ammonium nitrate → Nitrous Oxide + water.
Answers
Answer:
(a) Hydrogen gas combines with nitrogen to form ammonia.
H 2 (g)+N 2 (g)→NH 3
The balanced equation for this reaction can be written as:
3H 2(g)+N 2(g)→2NH 3
(b) Hydrogen sulphide gas burns in air to give water and sulphur dioxide.
H 2S(g)+O 2(g)→H 2O+SO 2
The balanced equation for this reaction can be written as:
2H 2 S(g)+3O 2 (g)→2H 2O+2SO 2
(c) Barium chloride reacts with aluminium sulphate to give aluminium chloride and a precipitate of barium sulphate.
BaCl 2 +Al 2 (SO 4 ) 3 →AlCl 3+BaSO 4 ↓
The balanced equation for this reaction can be written as:
3BaCl 2 +Al 2 (SO 4 )3→2AlCl 3+3BaSO 4 ↓
(d) Potassium metal reacts with water to give potassium hydroxide and hydrogen gas.
K+H 2O→KOH+H 2
The balanced equation for this reaction can be written as:
2K+2H 2O→2KOH+H 2
