An element is made of only one kind of atom, while a compound contains the atoms of two or more elements. For example, gold is made of only one kind of atom, so it is an element, but water is a mix of hydrogen and oxygen, so it is a compound.

Answer: The balanced chemical equation is $2KClO_3(s)\rightarrow 2KCl(s)+3O_2(g)$

Explanation:

A balanced chemical equation is one where all the individual atoms are equal on both sides of the reaction. It follows the law of conservation of mass.

For the given unbalanced chemical equation:

$KClO_3(s)\rightarrow KCl(s)+O_2(g)$

On the reactant side:

Atoms of K = 1

Atoms of Cl = 1

Atoms of O = 3

On the product side:

Atoms of K = 1

Atoms of Cl = 1

Atoms of O = 2

To balance the equation, we must balance the atoms by adding 2 infront of both $KClO_3(s)$ and $KCl(s)$ . Also, a coefficient of 3 must be written infront of $O_2(g)$

For the balanced chemical equation:

$2KClO_3(s)\rightarrow 2KCl(s)+3O_2(g)$
