Question

What is the type of the following reaction
a) displacement reaction
b) combination reaction
c) decomposition reaction
d) double displacement reaction

Answer 1

Displacement Reaction :- The reaction in which one element takes places of another element is known as displacement reaction.
Combination Reaction :- The reaction in which two reactants mixs and form new compound is know as Combination reaction.
Decomposition Reaction:- The reaction in which a compund displaces in 2 Reactants is known as decomposition Reaction
Double Displacement Reaction:- The Reaction in which two compounds or a group of atoms reacts and exchanges it ions is known as Double displacement Reaction..

Answer 2

Hey mate____

Here is your answer-____

Types of Chemical reaction :-

• Displaced reaction :-
The reaction in which the place of ion of a less reactive element in a compound is taken by more reactive element by formation of its own ions is called displacement reaction.

For eg. When zinc dust is added in copper sulphate solution a colourless zinc sulphate solution is formed.

• Combination reaction :-
The chemical reaction in which two or more reactants combine and form a single product is known as combination reaction.

For eg. When ammonia is heated with HCl then from ammonium chloride.

• Decomposition reaction :-
The chemical reaction in which two or more products formed from a single reactant is known as decomposition reaction.

For eg. When calcium carbonate is heated it decomposes into calcium oxide and carbon dioxide gas.

• Double Displacement reaction :-
The chemical reaction in which ions in the reactants are exchanged to form a precipitate is called double displacement reaction.

For eg. When potassium chromate is added into Barium sulphate solution then form yellow colour precipitate of Barium chromate.
