Exams were returned in class today. If you did not take the exam but intend to continue in class please let me know, I will be forwarding names of those who are not continuing in class to the registrar next week. If you were not in class today to pick up your exam, I will have your exam with me on Friday in class. The average on the exam was 110/150.
We began talking about Chapter 4. Stoichiometry is all about balancing chemical equations, converting grams to moles and moles to grams. If you're struggling with balancing chemical formulas or these gram-mole/mole-gram conversions, you need to practice, practice, practice. We'll continue on Friday.
