Respuesta :
The correct option is (2) decomposition.
In the balanced equation 2KClO3==> 2KCl + 3O2, as there is a reduction of oxygen therefore it is decomposition reaction.
What is decomposition reaction?
A chemical reaction that results in the breakdown of one reactant into two or more reactants is known as a decomposition reaction.
The general equation for decomposition is-
AB -> A + B
Where A & B are now the product molecules and AB is the parent (reactant) molecule.
Some key features of the decomposition reaction are-
- A combination reaction is the opposite of the a decomposition reaction. In such reactions, a single product is created form two or even more reactants.
- Decomposition processes are not always endothermic. Both endothermic and exothermic reactions can take place during decomposition. This one is more typical than the former, though.
- Extraction of metal from their ores is a significant use of decomposition processes. For instance, by putting calamine through a breakdown reaction, zinc can be extracted. The same process can be used to make sodium form sodium chloride (NaCl).
- A type of decomposition reaction known to be a double decomposition reaction involves the exchange of positive and negative ions between two constituent reactants to create two new molecules.
