Chemistry reactions final PLEASE help

Question

Match the following reactions with their types

Fe CuSO4 --> FeSO4 Cu

CaO H2O --> Ca(OH)2

NH4NO3 --> N2O H2O

C O2 --> CO2

A) double displacement reaction

B) decomposition reaction

C) combustion reaction

D) synthesis reaction

E) single displacement reaction

Answer 1

Fe + CuSO4 --> FeSO4 + Cu is single displacement

CaO + H2O --> Ca(OH)2  i a synthesis reaction

NH4NO3 --> N2O + H2O is a decomposition reaction

C + O2 --> CO2 is a combustion reaction

Answer 2

FeSO4 Cu is single displacement

Ca(OH)2 is synthesis

NH4NO3 is decomposition

CO2 combustion
