Today was the day of the unit test, but I missed class due to an orthodontist appointment. Since I missed class today I will most likely be taking the test tomorrow after school. I feel pretty confident about this unit so far, my only worry is finding molecular and empirical formulas. The method to finding them is quite tedious and requires a lot of time. Unfortunately the test has a time limit, which means I have to answer the questions rather quickly in order to finish in time. I have a few links to websites that might help out anyone else taking the test this week, and also might help on the final exam. Here they are:
Chemteam.info,
Purdue.edu,
Wisc.edu
Difference between empirical and molecular formulas
How to find empirical formulas
Your pictures on Empirical Formulas really helped me clear up what I was thinking, thank you. However I think that you could try putting some words in between your pictures to kinda even it out.
