Translate the following statements into chemical equations and then balance the equations: (i) Phosphorus burns in oxygen to give phosphorus pentoxide. (ii) Aluminium metal replaces iron from ferric oxide, Fe2O3, giving aluminium oxide and iron. (iii) Carbon disulphide burns in air to give carbon dioxide and sulphur dioxide. (iv) Barium chloride reacts with zinc sulphate to give zinc chloride and barium sulphate.

Translate the following statements into chemical equations and then  balance the equations: (i) Phosphorus burns in oxygen to give phosphorus pentoxide. (ii) Aluminium metal replaces iron from ferric oxide, Fe2O3, giving aluminium  oxide and iron. (iii) Carbon disulphide burns in air to give carbon dioxide and sulphur dioxide. (iv) Barium chloride reacts with zinc sulphate to give zinc chloride and barium sulphate.

Rifat Afreen · Accepted Answer

(i) Phosphorus burns in oxygen to give phosphorus pentoxide.
Equation:
P₄ + 5O₂ → 2P₂O₅
(ii) Aluminium metal replaces iron from ferric oxide (Fe₂O₃), giving aluminium oxide and iron.
Equation:
2Al + Fe₂O₃ → Al₂O₃ + 2Fe
(iii) Carbon disulphide burns in air to give carbon dioxide and sulphur dioxide.
Equation:
CS₂ + 3O₂ → CO₂ + 2SO₂
(iv) Barium chloride reacts with zinc sulphate to give zinc chloride and barium sulphate.
Equation:
BaCl₂ + ZnSO₄ → ZnCl₂ + BaSO₄
