Question

Write the balanced chemical equations for the following reactions:
(a) Calcium hydroxide `+` Carbon dioxide `to` Calcium carbonate `+` Water
(b) Zinc `+` Silver nitrate `to` Zinc nitrate `+` Silver
(c) Aluminium `+` Copper chloride `to` Aluminium chloride `+` Copper
(d) Barium chloride `+` Potasium sulphate `to` Barium sulphate `+` Potassium chloride

Answer 1

All these equations are in word form whereas the balanced equations are written in symbol form.
(a) `Ca(OH)_(2) + CO_(2) to CaCO_(3) + H_(2)O`
(b) `Pb + CuCl_(2) to PbCl_(2) + Cu`
(c) `BaCl_(2) + Na_(2)SO_(4) to BaSO_(4) + 2NaCl`
(d) `Zn + 2AgNO_(3) to Zn(NO_(3))_(2) + 2Ag`
