    You should look these words up on the internet, it's pretty self-explanatory once you know what they are - i'd hate to rob you of the privilege of knowledge lol If you want to double check, you can ask

    no, chromatography is a general word used for a lot of different processes, but the answer here is distillation - it involved heating a substance to evaporate compounds sequentially based on their BPs

    no problem, people learn at different rates. For this one, you need to know how to distinguish between physical and chemical properties. Take a look at this http://www.iun.edu/~cpanhd/C101webnotes/matter-and-energy/properties.html

    that's right, pH is a measure of \(H^+\) ions in a solution
