Solution

1. $C a O + H_{2} O ⟶ C a {(O H)}_{2}$
exothermic combination reaction.
Combination or synthesis A + B ----> AB

2. $C u S O_{4} + Z n ⟶ Z n S O_{4} + C u$
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. $N_{2} + {3 H}_{2} ⟶ {2 N H}_{3}$
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. $F e + 2 H C l ⟶ {F e C l}_{2} + H_{2}$
Substitution or Single Replacement A + BC ----> B + AC

5. $C + O_{2} ⟶ {C O}_{2}$
Combination or synthesis A + B ----> AB

6 $H_{2} S O_{4} + N H_{4} O H ⟶ {(N H_{4})}_{2} S O_{4} + H_{2} O$ .
Metathesis or Double Displacement AB + CD ----> AD + CB

7. $M g + F e_{2} O_{3} ⟶ M g O + F e$
Substitution or Single Replacement A + BC ----> B + AC
