Which statement correctly explains why the chemical equation below does NOT demonstrate the law of conservation of matter?



a
The number of Potassium (K) atoms are not equal on both the reactant and product side.
b
The number of Chlorine (Cl) atoms are not equal on both the reactant and product side.
c
The number of Oxygen (O) atoms are not equal on both the reactant and product side.
d
There are unequal numbers of all atoms on both the reactant and product side.

d

There are unequal numbers of all atoms on both the reactant and product side. This violates the law of conservation of matter, which states that matter cannot be created or destroyed in a chemical reaction. The number of atoms of each element must be equal on both sides of the equation.
