Answer 1

I hope this help ful for tou

Answer 2

There are main four types of chemical reactions which are as follow:

1.Combination Reaction
When two atoms react to form a compound, it is know as combination reaction.

eg. 2H2 + O2---> 2H2O


2. Decomposition Reaction
When a compound breaks into simple molecular substances from which it is made up of, it is know as decomposition reaction.

eg. 2H2O ---> 2H2 + O2


3. Displacement Reaction
When a highly reactive metal displaces a low reactive metal it is said to be displacement reaction.

eg. Ca + HCO3 ---> Ca2CO3 + H2


4. Double Displacement Reaction
When two compounds react to form two new compound it said to be double displacement.

eg. CaCO3 + NaOH ---> Ca(OH)2 + Na2CO3
