You're right , but unfortunately I do not quite know how to find this certain information.

Hi, In my chemistry class, we are doing a special stoichiometry project in which have to find out how much carbon dioxide is needed to extinguish a flame from a small candle. I was not sure of the best amount of CO2 needed for this task, so I was wondering if anyone would happen to know the best amount of CO2 needed (in mL or in L). Thanks in advance!

Hi, For a chemistry lab, we have to build different molecules, as well as show the polarity of the molecule. One of the molecules is TNT, and I was confused on the polarity of the molecule, and where it was positive and negative. Any help is appreciated!

Thanks for your advice, it worked!! But now my lab group is trying to figure out how we got benzoic. The day before, we had heated up some acetone with a mixture of benzoic and salt. Then we put it away in our drawer, and some of the acetone had evaporated. The next day, we found benzoic acid by itself, and we have no idea how it happened. Please help explain!!!

For a lab at school, we are given six substances which we have to separate and purify. The substances are benzoic acid, stearic acid, salt, sand, sawdust, and iron. We took out the iron with a magnet already, and got the sawdust out using a balloon and static electricity. However, my group is having trouble separating the rest of the mixture, and we only have one more class period to work on this lab. Also, we have many materials in class, but for safety reasons we cannot do something like heating alcohol (ethanol, acetone, etc.) at a high temp because of the flammability of the liquid. We really need some help and advice so we can complete the lab tomorrow!
