Question

Explain the type of chemical reactions with examples brainly

Answer 1

Answer:

1.Combination reaction

A rection in which a singl product is formed from two or more simple products is called combination reaction.

eg :- burning of coal - C + O2 gives Co2

2. Decomposition reaction

A reaction in which single reactant breaks down to give simpler products in the presence of heat,light or electricity.

eg :- heating of CaCo3 - It decomposes into CaO and Co2 in the presence of heat.

3.Displacement reaction

A reaction in which one element takes the position of another element in a compound.

eg:- When an iron nail dipped in copper sulphate solution - Fe + CuSo4 gives FeSo4 + Cu

4. Double displacement reaction

A chemical reaction in which there is an exchange of ions between the reactants

eg:- Reaction between Silver nitreate and Sodium Chloride - AgNo3 + NaCl gives AgCl + NaNo3

4.Oxidation

The process of addition of oxygen

eg:- C + O2 oxidises to Co2

5.Reduction

The process of removal of oxygen

eg:- Co2 reduces to C + O2
