Question

make a list of different types of chemical reaction which are useful to use and classify them into combination, decomposition,displacement,and double diplacement reaction

Answer 1

Decomposition reaction
H2O= H2 + O2

Combination reaction
Mg +O2 = MgO

Double Displacement reaction
Nacl + AgNo3= NaNo3 + AgCl

Displacement reaction
Fe + CuSo4= Cu + FeSo4


Hope this helps!
