The Mole is a unit
We use it to generalize how many atoms are in one group. Because they are so small we have a very large number, but it is the same idea as saying that there are 768 teaspoons in a gallon.
Reactivity Lab
You are going to set up your multi-well plate as illustrated below.
You need only a few bits of metal for this reaction. One curl of Mg, a 2-3 copper bits and a small pinch of the powdered metals.
For the liquid you only need enough to cover the metal.
Write this down: The color and a brief description of each of the substances you are working with.
Wait 5 minutes
Now describe them again. Is there any change.
Make a table that describes the changes. Example below.

A result section including the table above with your findings and any chemical reactions that occurred need to be turned in. You also need to include a few sentences that are why you believe that some of the wells had reactions but not others.
