Answer 1

Answer:

H2SO4+Zn---->ZnSO4+H2

Mg+HCl------>MgCl2+H2

H2SO4+Al---->Al2(SO4)3+H2

Fe+HCl---->FeCl3+H2

Answer 2

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.

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

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

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