Write the chemical equations for the reactions of zinc granules with:
$(i)$ Sulphuric acid
$(ii)$ Hydrochloric acid
$(iii)$ Aluminium chloride
$(iv)$ Sodium hydroxide
$(v)$ Nitric acid

(N/A) $(i)$ Zinc reacts with sulphuric acid to form zinc sulphate and hydrogen gas: $Zn(s) + H_{2}SO_{4}(aq) \rightarrow ZnSO_{4}(aq) + H_{2}(g)$
$(ii)$ Zinc reacts with hydrochloric acid to form zinc chloride and hydrogen gas: $Zn(s) + 2HCl(aq) \rightarrow ZnCl_{2}(aq) + H_{2}(g)$
$(iii)$ Zinc is less reactive than aluminium,so it cannot displace aluminium from aluminium chloride: $Zn(s) + AlCl_{3}(aq) \rightarrow \text{No reaction}$
$(iv)$ Zinc reacts with sodium hydroxide to form sodium zincate and hydrogen gas: $Zn(s) + 2NaOH(aq) \rightarrow Na_{2}ZnO_{2}(aq) + H_{2}(g)$
$(v)$ Zinc reacts with concentrated nitric acid to form zinc nitrate,nitrogen dioxide,and water: $Zn(s) + 4HNO_{3}(conc.) \rightarrow Zn(NO_{3})_{2}(aq) + 2NO_{2}(g) + 2H_{2}O(l)$
