Question

Example of decomposition reaction is
(a) 2SO2 + O2 → 2SO3
(b) 2KCIO3 → 2KCI + 3O2
(c) Mg + 2HCI → MgCl2 + H2
(d) HCI + NaOH → MgCl + H2O

Answer 1

Answer:

Explanation:

(b) 2KCIO3 → 2KCI + 3O2

This is decomposition reaction here

Hope its true and helps you....

Answer 2

Example of decomposition reaction is (b)

$\bold{2KCIO_3 \rightarrow 2KCI + 3O_2}$

Explanation:

• The decomposition reaction involves the breakdown of a compound into two or more elements.
• This reaction is opposite to combination reaction.
• This reaction involves breakdown of the bond between the elements in the compound. So, this reaction always requires greater energy for the initiation of the reaction.
• From question, the potassium chlorate is decomposed into potassium chloride and oxygen.
