Naming Compounds
On the homework for E.9 on the sixth edition, there was a compound called magnesium sulfate heptahydrate, which is MgSO4, but they didn't provide the actual formula. For the first test, do we have to know how to name compounds? If so, how do we do that?

Re: Naming Compounds
Magnesium sulfate heptahydrate, is actually MgSO4.7H2O
The raised dot separates the water of hydration. This compound contains a hydrate so in this form, magnesium sulfate heptahydrate exists as a crystal. But when this compound is heated, the water of hydration is lost and the crystals are lost.
I think we will have to know how to name compounds because a lot of homework questions expected that.

Re: Naming Compounds
Fundamentals D touches on naming compounds, so that could be helpful to review prior to the test. However I think we will be given the formulas for the compounds on this first test.

Re: Naming Compounds
When a formula has ---hydrate, the prefix represents the amount of H2O molecules present. So heptahydrate would be 7 H2O, trihydrate would be 3 H2O, and so forth. These are connected to the chemical formula with a dot.
