Answer #1

1) CuCl2(aq) + Na2CO3(aq) ------------> 2NaCl(aq) + CuCO3(s)

2) CuSO4(aq) + Na2CO3(aq) -----------> Na2SO4(aq) + CuCO3(s)

C) Pb(NO3)2(aq) + Na2CO3(aq)   -----------> 2NaNO3(aq) + PbCO3(s) CME

Pb+2(aq) + 2NO3-(aq) + 2Na+(aq) + CO3-2(aq) ------> 2Na+(aq) +    2NO3-(aq)   + PbCO3(s) CIE

Pb+2(aq) +  CO3-2(aq) ---------->   PbCO3(s) NIE

B) be sure simple ionisation or in presence of water
