Question

new one example each of displacement decomposition and combination reaction with explain ​

Answer 1

Explanation:

A combination reaction is a reaction where two or more elements or compounds combine to form a single compound. Such reactions may be represented by equations of the following form: X + Y → XY. The combination of two or more elements and form one compound is called combination reaction.

Chemical decomposition is the breakdown of a single entity into two or more fragments. Chemical decomposition is usually regarded and defined as the exact opposite of chemical synthesis. In short, the chemical reaction in which two or more products are formed from a single reactant is called a decomposition reaction.

C + O2 → CO2-combination reaction.

HCl(aq) + NaOH(aq) → NaCl(aq) + HOH(l)-decompostion reaction.
