Solution :-

(a) dilute sulphuric acid reacts with zinc granules:

=> dilute sulphuric acid + zinc → Zinc Sulphate + Hydrogen Gas

=> H2SO4(aq) + Zn → ZnSO4(aq) + H2(g)

(b) dilute hydrochloric acid reacts with magnesium ribbon.

=> dilute Hydrochloric + Magnesium → Magnesium Chloride + Hydrogen Gas

=> 2HCl(aq) + Mg → MgCl2(aq) + H2(g)

(c) dilute sulphuric acid reacts with aluminium powder.

=> dilute Sulphuric Acid + Aluminium → Aluminium Sulphate + Hydrogen Gas

=> 3H2SO4(aq) + 2Al(s) → Al2(SO4)3(aq) + 3H2(g)

(d) dilute hydrochloric acid reacts with iron filings.

=> dilute Hydrochloric Acid + Iron → Ferrous Chloride + Hydrogen Gas

=> 6HCl(aq) + 3Fe(s) → 3FeCl2(aq) + 3H2(g)
