Question

Give one example each of displacement decomposition and combination reaction with explanation

Answer 1

Explanation:

Combination reaction: When two or more reactants are reacts to yield the product then combination reaction is defined.

For example:Carbon and Oxygen combines to yield carbon dioxide.

$C+O_{2}\rightarrow CO_{2}$

Decomposition reaction: When single reactant decomposed into two or more product then decomposition reaction is defined.

For example:Decomposition of Calcium carbonate yield calcium oxide and carbon dioxide.

$Ca(CO)_{3} \rightarrow CaO+CO_{2}$

Displacement reaction: When highly reacted element displaces the least reacted element then displacement reaction is defined.

For example:Iron displace copper frpm copper sulphate.

$Cu(SO)_{4}+Fe\rightarrow Fe(SO)_{4}+Cu$.
