1.	Write word - equations and then balanced equations for the reactions taking place when (a) dilute sulphuric acid reacts with zinc granules. (b) dilute hydrochloric acid reacts with magnesium ribbon. (c) dilute sulphuric acid reacts with aluminium powder. (d) dilute hydrochloric acid reacts with iron filings.
Answer» Solution :(a) Sulphuric acid (aq) + Zinc (s) `rarr` Zinc sulphate(aq) + Hydrogen (g) `H_(2)SO_(4) (aq) rarr Zn(s) rarr ZnSO_(4) (aq) + H_(2)(g)` (b) Hydrochloric acid (aq) + Magnesium (s) `rarr` Magnesium chloride (aq) + Hydrogen(g) `2HCl(aq) +MG(s)rarr MgCl_(2)+ H_(2) (g)` (c) Sulphuric acid + Aluminium (s) `rarr` Aluminium sulphate (aq) + Hydrogen (g) `3H_(2) SO_(4) +2Al(s) (SO_4)_(3) (aq) +3H_(2)(g)` (d) Hydrochloric acid (aq) + Iron(s) `rarr` Iron chloride (aq) + Hydrogen (g) `2HCl(aq) + FE(s) rarr FeCl_(2) (aq) + H_(2)(g)`
