Dr. Forrester explains how we use minerals in our daily lives.

Double replacement chemical reactions, also known as precipitation reactions, are reactions where 2 elements are replaced. But you have to make sure that you replace the correct elements! In this video, we show you not only how to...

A polyatomic ion is an ion that is made up of multiple elements. Whenever we have a polyatomic ion present, we are not going to change the name at all. The name of the polyatomic ion will stay just as it is. So when we look at the ionic...
