Explain the type of chemical reactions with examples brainly
Answers
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
