Question

Complete the missing components/variables given as x and y in the following reactions 

(a) Pb(NO₃)₂ (aq) + 2KI(aq) → PbI₂ (x) + 2KNO₃(y) 

(b) Cu(s) + 2AgNO₃ (aq) →Cu(NO₃)₂(aq) + x(s)

 (c) Zn(s) + H₂SO₄(aq) →ZnSO₄(x) + H₂(y) 

(d) \(CaCO_3(s) \overset{x} \rightarrow CaO(s) + CO_2(g)\)

Answer 1

(a)  x → (s) y → (aq) 

(b) x →2Ag 

(c) x → (aq) y → (g) 

(d) x→ Heat
