Question

give balanced chemical equations
a) aluminium carbide + water - aluminium hydroxide + methane
b) iron pyrites + oxygen - ferric oxide + sulphur dioxide
c) potassium permaganet+ hydrochloric acid - potassium chloride + manganese chlride+ chlorine + water
d) aluminium sulphate + sodium hydroxide - sodium sulphate + sodium metaaluminate+ water

Open in App

Solution

Al₄C₃ + 12H₂O = 4Al(OH)₃ + 3CH₄

4FeS₂ + 11O₂ = 2Fe₂O₃ + 8SO₂

2KMnO₄+ 16 HCl → 2 MnCl₂+ 5 Cl₂ + 2KCl + 8H₂O

Al₂(SO₄)₃ + 8NaOH = 3Na₂SO₄ + 2NaAlO₂ + 4H₂O
