Write the balanced chemical equation of the reaction. Potassium permanganate + Hydrochloric acid → Potassium chloride + Manganese chloride + Chlorine + Water

Balanced equations are those whose coefficients result in equal numbers of atoms for each element in the reactants and products. 2 KMnO 4 + 16 HCl → 2 KCl + 2 MnCl 2 + 5 Cl 2 + 8 H 2 O

Write the balanced chemical equation of the reaction. Potassium permanganate + Hydrochloric acid → Potassium chloride + Manganese chloride + Chlorine + Water

Balanced equations are those whose coefficients result in equal numbers of atoms for each element in the reactants and products. 2 KMnO 4 + 16 HCl → 2 KCl + 2 MnCl 2 + 5 Cl 2 + 8 H 2 O

Write the balanced chemical equation of the reaction. Iron pyrites + Oxygen → Ferric oxide + Sulphur dioxide

Balanced equations are those whose coefficients result in equal numbers of atoms for each element in the reactants and products. 4 FeS 2 + 11 O 2 → 2 Fe 2 O 3 + 8 SO 2

Balance the equation. P + HNO 3 → NO 2 + H 2 O + H 3 PO 4

White phosphorus react with nitric acid to form phosphoric acid, nitrogen dioxide and water. Phosphorus is a strong reducing agent and reduces HNO 3 into NO 2 . P + 5 HNO 3 → 5 NO 2 + H 2 O + H 3 PO 4

Balance the equation. HNO 3 + H 2 S → + NO 2 + H 2 O + S

Nitric acid reacts with hydrogen sulphide gas to produce nitrogen dioxide, water and solid sulphur. 4 HNO 3 + 2 H 2 S → 4 NO 2 + 4 H 2 O + 2 S

Balance the equation. H 2 O + Cl 2 → HCI + O 2

Chlorine react with water to produce hydrogen chloride and hypochlorous acid. It is not very stable and easily decomposes, when exposed to sunlight, yielding oxygen. H 2 O + Cl 2 → 2 HCI + 1 2 O 2
