Zinc metal reacts with Hydrochloric acid to produce an aqueous solution of Zinc chloride and hydrogen gas:
Zn + 2HCl → ZnCl2 + H2 ↑
When solid Mercury (II) Oxide is heated, Liquid mercury and oxygen gas is produced.
heat
2HgO ------2Hg (l) + O2 (g)
and
The equation
BaCl2 + Al2(SO4)3 --> BaSO4 + AlCl3
The balanced equation would be:
3BaCl2 + Al2(SO4)3 --> 3BaSO4 + 2AlCl3
Zn + 2HCl → ZnCl2 + H2 ↑
When solid Mercury (II) Oxide is heated, Liquid mercury and oxygen gas is produced.
heat
2HgO ------2Hg (l) + O2 (g)
and
The equation
BaCl2 + Al2(SO4)3 --> BaSO4 + AlCl3
The balanced equation would be:
3BaCl2 + Al2(SO4)3 --> 3BaSO4 + 2AlCl3
