Question
Choose the response that best answers the question "Why do we not change subscripts when balancing a chemical equation?"
It's fine to do once in awhile, but don't make a habit of it.
We never change subscripts because atoms are neither created nor destroyed. This is part of the law of conservation of matter.
Compounds composed of the same elements and having different subscripts are different substances.
We can change subscripts. We can't change coefficients.
There's no real reason not to, it's just something that is not done.

Explanation / Answer
we can’t change subscript because changing subscript means a different compound
For example PCl3 and PCl5 are different compound as their subscripts are different
So, option C is correct
Answer: c
