biological medium is water for earth- what is used to sustain
water molecule is a polar molecule: the opposite ends have opposite charges
-polarity allows water to form hydrogen bonds
properties that allow water to facilitate an environment for life ar

In this experiment you will observe the dehydration of a hydrated salt, and will calculate both the percent water by mass and the correct formula for the hydrated salt. By making sure the percent error is less than 5%; %Hydration Theoretical-%
