Write the balanced chemical equations for the following and identify the type of reaction in each case :
(a) `"Barium chloride (aq)"+"Potassium sulphate (aq)"to"Barium sulphate (s)"+"Potassium chloride (aq)"`
(b) `"Zinc carbonate (s)"to "Zinc oxide (s)"+ "Carbon dioxide (g)"`
(c ) `"Hydrogen (g)" + "Chlorine (g)"to "Hydrogen chloride (g)"`
(d) `"Magnesium (s)"+"Hydrochloric Acid(aq)"to "Magnesium chroride (aq)"+ "Hydrogen (g)"`

Text Solution

Verified by Experts

(a) `BaCl_(2) (aq)+K_(2)SO_(4)(aq) to BaSO_(4)+2KCl(aq)`
This is a double displacement reaction.
(b) `ZnCO_(3)(s)toZnO(s)+CO_(2)(g)`
This is a decomposition reaction.
(c ) `H_(2)(g)+Cl_(2)(g)to2HCl(g)`
This is a decomposition reaction.
(d) `Mg(s)+2HCl(aq)toMgCl_(2)(aq)+H_(2)(g)`
This is a combination reaction.
