Summary

I learned some basic chemistry for the first time in my life thanks to the Khan Academy. The videos and exercises are very useful. However, since I wasn’t familiar with the periodic table, reading some of the chemical formulas given in the exercises was confusing and forced me to go to the periodic table repeatedly and basically “hunt” for the elements and their basic data over and over again.

This program is just a small effort towards making that experience go a little smoother. Type in your chemical formulas, and receive useful information back!
