Question

we have to balance it so how answer plz with clear explanation​

Answer 1

Answer:

2KClO3 -----> 2KCl + 3O2

Explanation:

only oxygen atoms are not balanced.

as there are odd number of oxygen atoms in reactant species and even number or oxygen atoms in product so we have to see how they can be balanced. in this case 3 and 2 are balanced with 2 and 3 respectively. after that just balance the K and Cl atoms also.
