(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 filing.

(a) dilute sulphuric acid reacts with zinc granules:
Word equation: dilute Sulphuric acid + Zinc → Zinc Sulphate + Hydrogen Gas
Balanced equation: $H_{2} SO_{4}( aq) \ +\ Zn\ \rightarrow \ ZnSO_{4}( aq) \ +\ H_{2}( g)$

(b) dilute hydrochloric acid reacts with magnesium ribbon.
Word equation: dilute Hydrochloric acid+ Magnesium → Magnesium Chloride + Hydrogen Gas
Balanced equation: $2HCl( aq) \ +\ Mg\ \rightarrow \ MgCl_{2}( aq) \ +\ H_{2}( g)$

(c) dilute sulphuric acid reacts with aluminium powder.
Word equation: dilute Sulphuric acid + Aluminium → Aluminium Sulphate + Hydrogen Gas
Balanced equation:  $3H_{2} SO_{4}( aq) \ +\ 2Al( s) \ \rightarrow \ Al_{2}( SO_{4})_{3}( aq) \ +\ 3H_{2}( g)$

(d) dilute hydrochloric acid reacts with iron filings.
Word equation: dilute Hydrochloric Acid + Iron(Ferrum) → Ferrous Chloride + Hydrogen Gas
Balanced equation: $6HCl( aq) \ +\ 3Fe( s) \ \rightarrow \ 3FeCl_{2}( aq) \ +\ 3H_{2}( g)$
