Question

Identify the type of reaction(s) in the following equations with suitable reason.
(ii) Pb(NO3)2  (aq)+ 2KI (aq) ——–>Pbl2 (s) + 2KNO3  (aq)
(iii) CaO (s) +  H2O (l) ——–> Ca(OH)2  (Aq)
(iv) CuSO4   (aq) + Zn (s) ——–> ZnSO4  (aq) + Cu (s​

Answer 1

ii) Double displacement reaction since both lead and potassium gets displaced from their ionic solvents

iii) Combination reaction since two substances join to form a new compound

iv) Displacement reaction since copper gets displaced by zinc
