Write word equations and then balance equations for the reaction taking place when-
(a) dilute sulphuric acid reacts with zinc granules.
(b) Dilute hydrochloric acid reacts with magnesium ribbon.
(c ) dilute sulphuric acid react with aluminium powder
(d) dilute hydrochloric acid reacts with iron fillings.

Explanation

(a) Zinc + Sulphuric acid `to` Zinc sulphate + Hydrogen
`Zn(s)+H_2SO_4(aq) to ZnSO_4(aq)+H_2(g)`
(b) Magnesium+ Hydrochloric acid `to` Magnesium chloride + Hydrogen
`Mg(s)+2HCl(aq) to MgCl_2(aq)+H_2(g)`
(c ) Aluminium+ Sulphuric acid `to` ALuminium sulphate+ Hydrogen
`2Al(s)+3H_2SO_4 (aq)to Al_2(SO_4)_3+3H_2(g)`
(d) Iron+ Hydrochloric acid `to` Ferrous chloride+ Hydrogen
`Fe(s)+2HCl(aq)to FeCL_2(aq)+H_2(g)`
