What is an anion?

An ion that is formed when electrons are gained, giving it a negative charge.

100

What type of bond is in a molecular compound?

Covalent

What does the Law of Conservation of Mass have to do with balancing equations?
Matter can be neither created nor destroyed. This means that the number of atoms of each element on either side of the equation must be the same, they are simply rearranged.
