  1. Thanks a lot. Seriously, Mr. Anderson, you are doing a great job. It is really awesome and very very helpful. By the way, how can you teach biology as well as chemistry. You're sure a genius. Can you teach physics too?
    P.S Thanks to Mrs. Anderson also for all the work she its doing behind the screen.

  2. Thanks so much. I am only teaching Biology this year. However since AP Chemistry is using a new curriculum this year I figured that it would be a good time to create some Chemistry videos. It has been a lot of work but I have also learned a ton. I will pass on the thank you to my wife. I think she is awesome as well.

  3. Hi Mr Anderson, I'm Tom and I live in the UK. I received my AS level results yesterday and got an A (90%) in my Biology. I just wanted to say a MASSIVE thank you to you because your videos were so incredibly helpful. I hope you keep making them so I can continue my success next year and hopefully get into Cambridge University. Keep the videos going because they're fantastic!

  4. air scatters light, therefore it's not a solution.  we know air scatters light because the sky is blue but the light from the sun is white.

  5. Lab: added distilled water to MgO. Liquid was opaque white. Looked pretty smooth. Tested with Litmus and found it to be a base. I looked this up and everything I found says MgO is not soluble in water. Why? If it wasn't soluble, why did it change the litmus paper?

    Added CuCO3 green powder to distilled water. First the water turned green and I thought it had dissolved. Litmus papers didn't change except the blue Linus was a little purplish at the edges. The powder seemed to separate from the water after several minutes. Does this mean it wasn't soluble?

  6. My AP Chemistry teacher taught us a good way to remember the difference between a solute and a solvent. A solute- u dissolve, solvent-dissolver… match up the u's and the v's. I also want to say that I really appreciate you putting these videos up, it's really helping me review what I just reviewed by looking at my notes. Thanks so much 🙂

  7. That map at the start summarised literally everything I had troubles with. Thank you so much xD

  8. Mr. Andersen , In Column Chromatography at 4:25 is it ABSORBENT or ADSORBENT ?
