Question

Write balanced equations for the reactions of
(a) Zinc with hydrochloric acid
(b) Magnesium with sulphuric acid​

Answer 1

Answer:

Zinc + Hydrochloric acid  = Zinc Chloride

Zn + Hcl = ZnCl

Answer 2

Answer:

a) Dilute sulphuric acid reacts with zinc granules to produce zinc sulphate and hydrogen gas H 2 SO 4(aq)+Zn(s)→ZnSO4(aq)+H 2(g)

(b) Dilute hydrochloric acid reacts with magnesium ribbon to produce magnesium chloride and hydrogen gas.

2HCl(aq)+Mg(s)→MgCl 2(aq)+H 2(g)

(c) Dilute sulphuric acid reacts with aluminium powder to produce aluminium sulphate and hydrogen gas.

3H 2 SO4 (aq)+2Al(s)→Al 6 (SO 4 ) 3 (aq)+3H 2 (g)

(d) Dilute hydrochloric acid reacts with iron filings to produce ferric chloride and hydrogen gas.

6HCl(aq)+Fe(s)→2FeCl 3 (aq)+3H 2(g)
