Question

2Pb(NO3)2(aq) + 2KI (aq)gives PbI2(x)+2KNO3(y) 1 point s and Ag aq and g s and aq Heat and s

Answer 1

Answer:

(a) Pb(NO3 )2 (aq) + 2KI (aq) ⇨ PbI2 (s) + 2KNO3 (a)

(b)Cu (s) + 2AgNO3 (aq) ⇨ Cu(NO3 )2 + Ag (s)

(c)Zn (s) + H2SO4 (aq) ⇨ ZnSO4 (aq) + H2 (g)

(d)CaCO3 + Heat ⇨ CaO (s) + CO2 (g)
