When the following equation is balanced, kclo3 (s) → kcl(s) + o2(g), the coefficient of kclo3 is

The coefficient of KClO₃ is 2.

Explanation:

Chemical equation:

KClO₃    →   KCl  + O₂

Balance chemical equation:

2KClO₃    →   2KCl  + 3O₂

The balanced chemical equation must have equal number of atoms in both side of equation.

In given chemical reaction without balancing, there are two oxygen atoms on right side while on the left side three atoms are present. So we multiply it with the coefficient two to balance the atoms of oxygen. The number of potassium atoms and chlorine atoms on left side becomes two by adding coefficient two, that's why we also add two with KCl on right side to balance the equation.

it's all four options.
