Question

Balance the following reaction:

1.when ammonium hydroxide is added to a solvent of iron (II) Sulphate , a green ppt of iron (II) hydroxide and ammonium sulphate is formed.

2.Zinc reacts with dilute hydrochloric acid to form zinc chloride and hydrogen gas liberated.

Answer 1

1) The reaction is a double displacement reaction, and occurs as follows:

NH4OH+FeSO4 = (NH4)2SO4 +Fe(OH)2

(aqeous) (aqeous) (aqeous) (solid)

(the balanced equation and the compound sates)



2)Zinc + Hydrochloric acid * Zinc chloride + hydrogern Zn(s)+ HCI(aq) * ZnCl2(aq) + H2(g)

Balanced:

Zn(s) + 2HCI(aq) * ZnCl2(aq)H2(g)
