This video breaks down in depth all cases where Le Chatelier's principle applies. Students are often times familiar when this concept is applied in one aspect, but not in others. This is a 14 minute video that will teach and clarify the Le Chatelier concept.
Ask a tutor:
What happens to a reaction when heat is added?
Where does the reaction shift when volume is increased?
SOLVENT, SOLUTE, AND SOLUTION
For solutions students should review intermolecular forces discussed in previous courses to better understand why some substances mix and others do not.
The beginning week in Chem 1B students will review solutions. Students should be able to Differentiate the three terms solvent, solute and solution.
This is a graph that shows the solubility (in grams) of common salts in 100g of water at certain temperatures. The lines are where the solution is saturated, anywhere under the line is not saturated, and anythere above is super saturated.
INTERMOLECULAR FORCES
This topic was covered in CHEM1A, however many of us forget it, so here is a video to help you remember.
Ion-ion interactions
Ion-dipole
Dipole-Dipole
van der Waals (London Forces)
While watching this video, take notes on the different forces. Perhaps, define, and list key features of each force, if applicable also write down a few examples.
Which force is the strongest? Which one is the weakest??
Ask a tutor:
If you feel like you've understood the topic, ask for practice questions.
If you have any doubts, if any topic isn't fully clear, let us know, we can help you.
Tips to better remember/understand this topic.
I have found this video helpful in explaining the different interaction between molecules and how that plays a role in solubility. While watching this video you should be taking notes on Van Der Waals forces, london dispersion, and hydrogen bonding. After finishing the video, write down everything you can remember about molecular interactions. This will allow you to see what you need to pay more attention to and go over. Students can visiting the tutorial center for more in depth explanation of these concepts, as well as going over practice problems.
CHEMICAL KINETICS
If you click on this video you can find further information on the Laws of Thermodynamics. On the side of the website, there are links to videos explaining the other laws.

Chem 1B Mock Exam Chapter 16 and 17
Created by - Manharsh S Sekhon (October Monthly Project)
Topics we need to work on
Nuclear Chemistry
Electrochemistry
Acids and Bases
Free Energy and Thermodynamics
Radioactivity
Radiation
This is an introduction to radiation for general chemistry students. It will be covered at the very end of the semester, but it is essential to know what radiation means.
This video introduces what decay is and how it effects radioactive elements. These videos are great for having as background information so when you talk about these topics in class you will have some knowledge of the subject.
