Identify the type of reactions:
1. CaO+H2O-----Ca(OH) 2
2. CuSO4 + Zn ZnSO4+Cu
3. N2 + 3H2 ----> 2NH3
4. Fe+2HCl---->FeCl2
5. C+O2--->CO2
6.H2SO4 + NH4OH ----- H2O + (NH4)2SO4
7.Mg +Fe2O3 ------ Fe + MgO
1. CaO+H2O⟶Ca(OH)2
exothermic combination reaction.
Combination or synthesis A + B ----> AB
2. CuSO4+Zn⟶ZnSO4+Cu
It is a displacement reaction. Due to high reactive metal zinc displaced copper from its ion.
Substitution or Single Replacement A + BC ----> B + AC
3. N2+3H2⟶2NH3
It is an example of COMBINATION REACTION because two small molecules are combining to form a bigger one.
Combination or synthesis A + B ----> AB
4.Fe+2HCl⟶FeCl2+H2
Substitution or Single Replacement A + BC ----> B + AC
5.C+O2⟶CO2
Combination or synthesis A + B ----> AB
6 H2SO4+NH4OH⟶(NH4)2SO4+H2O .
Metathesis or Double Displacement AB + CD ----> AD + CB
7. Mg+Fe2O3⟶MgO+Fe
Substitution or Single Replacement A + BC ----> B + AC
