In this animated object, learners examine the formation of ester bonds in the synthesis of lipids using triglyceride biosynthesis as an example. Ester bond formation is described as a dehydration synthesis reaction.

Atomic weights are used to convert the mass of a sample into the number of moles of the element in the sample and vice versa. Four examples are provided for practice.

Learners examine phase diagrams that show the phases of solid, liquid, and gas as well as the triple point and critical point.

In this interactive lesson, students examine the quantitative relationship between chemicals in a balanced mathematical equation.
