Question

Complete the missing components/ variables given as x and y in following reacations. (1) Pb(NO₃)₂(aq) + 2KI(aq) → PbI₂(x) + 2KNO₃(y) (2) Cu(s) + 2AgNO₃(aq) → Cu(NO₃)₂(aq)+ x(s) (3)H₂SO₄(aq) + Zn(s) → H₂(y) + ZnSO₄(x) (4) CaCO₃(s) →x CaO(s) + CO₂(g)

Solution

(1) Pb(NO₃)₂(aq) + 2KI(aq) → PbI₂(x) + 2KNO₃(y); x= ppt. (s), y= (aq) (2) Cu(s) + 2AgNO₃(aq) → Cu(NO₃)₂(aq)+ x(s); x= Ag (3)H₂SO₄(aq) + Zn(s) → H₂(y) + ZnSO₄(x); x=(aq), y=(g) (4) CaCO₃(s) →x CaO(s) + CO₂(g); x= heat
