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

(a) H2SO4 (aq) + Zn (s) → ZnSO4 (aq) + H2 (g)

(b) 2HCl (aq) + Mg(s)→ MgCl2 (aq) + H2(g)


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


(d) 6HCl (aq) +2Fe (s) → 2FeCl3(aq) +3H2(g)
