Chemistry 1-15-21 Polymers & Empirical & Molecular Formulas HW

CHEMISTRY: We finally finished the chapter! Did you realize molecules could be that large? And so many of them. But don’t you think polymers are cool? The first vodcast below is the rest of the lecture that you need for polymers. Fast forward to the part where we left off in your class. Some items for contemplation: why are certain plastics recyclable and others not…and what about dishwasher and microwave safe? Hmmmmm…

Below that is what we actually did first in class yesterday – our look at the homework from last night – empirical and molecular formulas. Great stuff to review as you study for the test!
