Balance the equations given below:
(1) Aluminium carbide + water -> Aluminium hydroxide + Methane
(2) Iron Pyrites (FeS₂) + Oxygen -> Ferric Oxide + Sulphur dioxide
(3) potassium permanganate + hydrochloric acid -> Potassium chloride + Manganese chloride + Chlorine + water
Answers
Balanced chemical equations are written below-
(1) Aluminium carbide + water -> Aluminium hydroxide + Methane
Formula for aluminium carbide is Al4C
Formula for water is H2O
Formula for aluminium hydroxide is
Al(OH)3
Formula for methane is CH4
Al4C3 + 12H2O -> 4Al(OH)3 + 3CH4
(2) Iron Pyrites (FeS₂) + Oxygen -> Ferric Oxide + Sulphur dioxide
Formula for oxygen is O2
Formula for ferric oxide is 2
Fe2O3
Formula for sulphur dioxide is SO2
4FeS₂ + 11O2 -> 2Fe2O3 + 8SO2
(3) potassium permanganate + hydrochloric acid -> Potassium chloride + Manganese chloride + Chlorine + water
Formula for potassium permanganate is KMnO4
Formula for hydrochloric acid is HCl
Formula for potassium chloride is Lack
Formula for manganese chloride is MnCl2
Formula for chlorine gas is Cl2 2KMnO4 + 16HCl -> 2KCl + 2MnCl2 + 8H2O + 5Cl2
