Write the balanced symbol equations for the following reactions. Reaction between calcium and hydrochloric acid. Reaction between magnesium and sulphuric acid. Reaction between zinc and nitric acid. Reaction between zinc carbonate and sulphuric acid. Reaction between iron ( III ) carbonate and hydrochloric acid.

A balanced chemical equation or symbol equation should contain equal number of atoms on both the sides of the equation. Therefore, the given symbol equations can be balanced as, Reaction Balanced symbol equation Reaction between calcium and hydrochloric acid. Ca + 2 HCl → CaCl 2 + H 2 Reaction between magnesium and sulphuric acid. Mg + H 2 SO 4 → MgSO 4 + H 2 Reaction between zinc and nitric acid. Zn + 2 HNO 3 → Zn NO 3 2 + H 2 Reaction between zinc carbonate and sulphuric acid. ZnCO 3 + H 2 SO 4 → ZnSO 4 + H 2 O + CO 2 Reaction between iron III carbonate and hydrochloric acid. Fe 2 CO 3 3 + 6 HCl → 2 FeCl 3 + 3 H 2 O + 3 CO 2
