Reaction of reactivity water

metal + water: Ca + 2 H2O → Ca(OH)2+ H2

Zn + 2Hcl → ZnCl2 +H2

Fe + H2O(g) -> FeO + H2

Pb + CuSO4 - > PbSO4 + Cu

Fe+CuO →FeO + Cu

Na2CO3 →

|_ Na is a very reactive M, hence Na2CO3 is very thermally stable , hence it cannot decompose on heating

ZnCO3 → ZnO + CO2

Au2CO3 → 4Au + O2 + 2 CO2

2 PbO + C → 2 Pb + CO2

FeO + H2 → Fe + H2O

first 4 can react with water

steam can react until iron , can form

all until hydrogen can react with

Zn - Au can be reduced by carbon

K please

Na stop

aluminium is a special metal that is rarely use in reaction, as there is a layer of aluminium oxide
