Answer:
Answer
a) Dilute sulphuric acid reacts with zinc granules to produce zinc sulphate and hydrogen gas
H2SO4(aq)+Zn(s)→ZnSO4(aq)+H2(g)
(b) Dilute hydrochloric acid reacts with magnesium ribbon to produce magnesium chloride and hydrogen gas.
2HCl(aq)+Mg(s)→MgCl2 (aq)+H2(g)
(c) Dilute sulphuric acid reacts with aluminium powder to produce aluminium sulphate and hydrogen gas.
3H SO4(aq)+2Al(s)→Al2 (SO4)3 (aq)+3H2(g)
(d) Dilute hydrochloric acid reacts with iron filings to produce ferric chloride and hydrogen gas.
6HCl(aq)+Fe(s)→2FeCl3 (aq)+3H2 (g)
