Answers & Comments
Verified answer
Explanation:
(i) Mg + CuSO4 = MgSO4 + Cu
This is a Displacement reaction
(ii) (NH4)2Cr2O7 = Cr2O3 + 4 H2O + N2
This is a Double decomposition reaction
(iii) H2O + CO2 = H2CO3
This is a Decomposition reaction
(iv) CaO + 2HCl = CaCl2 + H2O
This is a Neutralisation reaction
