Answer:

Answer:

D

Explanation:

KClO3 ==> KCl + O2

         1  K  1

         1  Cl  1

         3  O  2

There are a different amount of oxygen atoms so this equation is not balanced

KClO3 ==> 3KCl + O2

        1  K  3

        1  Cl 3

         3 O 2

None of the elements have the same number of atoms on either side of the equation therefore this equation is not balanced.

2KClO3 ==> KCl + 3O2

          2  K   1

          2  Cl  1

          6  O   6

The number of potassium atoms and chlorine atoms is different on both sides of the equation therefore this equation is not balanced.

2KClO3 ==> 2KCl + 3O2

          2  K   2

          2  Cl  2

          6  O   6

The number of atoms of each element are the same on both sides therefore this equation is balanced.
