why do we need to balance chemical equations
we have to have an equal number of atoms on both sides
200
What type of substance would an element be under?
Pure substance because an element is the fartheset it can be broken down to.
200
What is a Polyatomic Ion?
Ions that are made up of more than one element

What happens in a chemical change that doesent happen in a physical change?
its not the same substance anymore the particles dont stay the same its hard to reverse bubbles form prectipitate

If you were to write a chemical equation for a base how would you know it was a base not acid or any tpe of ion?
In the equation it would have hydroxide (OH) at the end of it.
