Unit 5 & 6: The mole
|
The foundation for practically every aspect of chemistry is the number of molecules in a sample. Just as eggs are counted by the dozen (12) and shoes by the pair (2), molecules are counted by the mole (6.02 x 1023). This unit will introduce this topic, and how to balance chemical reactions We will also begin analytical chemistry, where we will experimentally determine the formula of a compound from its percent composition. Our first day of unit 5 has us covering how to utilize Avogradro's number, the mole. We also watched this Ted-Ed video, and went over atom/mole conversions. This lecture also has a project attached to it, the mole analogy. | ||||
Our Mole Analogy project is worth a test grade. Your assignment (linked below) is to create an analogy for just how big a mole is and create an 8" x 11" poster of said analogy. There are also two examples linked below.

Next we went over molar conversions, and using Avogadro's number to discuss the mass of various compounds. This however is the end of unit 5, next we will start unit 6 -- Analytically Chemistry. |

|
Unit 6 starts with analytical chemistry. Determining the formula of compounds, both their molecular formulas and empirical formulas |
|
We finish unit 6 up by covering types of chemical reactions, as well as balancing. Next class we will take the unit 5 & 6 test! |
