Let's imagine that we were going to start a company that produces
spectroscopes to sell to general chemistry students. To ensure that all the

hope this helps
There's a certain ph or acidic level to all things...and also the chemical formula can be stable from one substance and if another substance mixes and makes the new substance unstable then u start to see a chemical change
There are <em>three</em> possibilities:
