    I can't imagine what fluorhalantimonic acid smells like. Vinegar as we all know smells bad, sulphuric acid smells like… well… sulphur (so very unpleasant), I would have to guess then that fluorhalantimonic acid probably smells almost as bad as Thioacetone.

    1. Thioacetone is a thione, not a thiole
    2. Fluoroantimonic acid is H2SbF7, not H2SbF6

    one question thow. about Azidoazide Azide. I don't know much about this stuff. But C2N14, if you look at the picture of this compound, you can see 14 nitrogen atoms, but where are the 2 carbons ?

    Why are lesser-known toxic paints like cadmiums and cobalts toxic?

    Or, how are chemical compounds transformed to be used as pigments in paint?

    Or...why are fluorescent colors not lightfast?

    Honestly I just want to see an episode about paint and pigments—the chemistry is absolutely fascinating.

    Long story short i was in a chemistry class and we were writing down some covalent molecules and all the other students wrote really simple every day molecules and I wrote chlorine trifluoride because ironically last night I watched this video and this was the conversation my teacher had.

    Teacher: "Oh wow chlorine trifluoride, that's a pretty dangerous chemical"

    Me: "oh I know. I'm aware."

    Teacher: "you know? How?"

    Me: "I have my ways."

    somebody please help me find this video I once saw of a chemical reaction between 2 or 3 household thingy's in a bottle. It wasn't mentos and coke or anything with baking soda , and it wasn't a good ol works bomb. It was like the guy added the second or 3rd thing and the guy stood back and there was a firey violent reaction. Dammit I forget.
