Different types of chemical reactions with ecample

Answer 1

Q. Different type of chemical reactions with example?

Ans :-

Chemical Reaction :- The reaction in which two or more reactant together to form a new product under some suitable condition.

There is five type of chemical reactions :-

1) Combination or Addition reaction :- The reaction in which two reactant react together to form a single product is called combination reaction.

The general formula is $[A + B → AB]$

Ex:- $C + O _2 →CO_2$

$H_2 + O_2 →2H_2O$

2) Decomposition reaction :- The reaction in which a single reactant break down in to two or more simpler products in agency of heat,light and electricity is called decomposition reaction.

The general formula is $[ AB → A + B]$

Ex:- $CaCO_3→ CaO + CO_2$

3) Displacement reaction :- The reaction in which a reactive metal displaces a less reactive metal from its salt solution is called displacement reaction.

The general formula is $[A + BC → AC + B]$

Ex:- $Na + CuSO_4 → NaSO_4 + Cu$

4) Double - Displacement /precipitation reaction :- The reaction in which two compounds exchange their ions and one of the substance form is insoluble in nature is called double displacement reaction.

The general formula is $[AB + CD → AC + BD ]$

Ex:- $BaCl_2 + Na_2SO_4→NaCl + BaSO_4↓$

5) Redox Reaction :- The reaction in which oxidation and reduction taking place simultaneously is called redox reaction.

Ex :- $CuO + H_2 → Cu + H_2O$
