Answer 1

Answer:

1) ZnCO - ZnO + CO2 is a decomposition reaction as ZnCO gets decomposed into two different compounds.

2) Pb + CuCl - PbCl + Cu is a displacement reaction as Pb displaces Cu as Pb is more reactive than Cu

3) H+Cl - 2HCl is a combination reaction

4) CaCO- CaO+ CaO is a decomposition reaction

5) NaCl+AgNO3 - AgCl + NaNO3 is double displacement reaction

6) 3H + N - 2NH3 is combination reaction
