    "Your fat friend sweating like a pig" ..I cracked up so hard watching him say it.
    such gold.

    Even though I'm just a Grade Eleven Chem student --- your video have helped me understand everything that my teacher hasn't touched on enough for us to get 100 on our homework and labs.
    So thanks for helping ace chem this year :3

    "your fat friend is running around in a T-shirt and saying 'It's too hot!' and sweating like a pig"
    I laughed out loud!

    I am a bricklayer and I am impressed that she actually pronounced slaking the correct way. I also used to take care of swimming pools and hot tubs. It was fun adding the calcium to the pool because sometimes I would put some calcium in a bucket of water and watch it heat up and then dump it quickly into the pool. I almost melted a bucket once doing that, but it was usually pretty fun.

    @volound You must be new to the channel. The professor is our hero.

    @TheBetterGame if i thought comment wars were bad then i would probably completely agree.
    but although comment wars are not normally pleasant and not much good seems to comes of them, theyre not really harmful to anyone. least of all the channel owners whose video relevance increases in the searches with more comments.

    The woman, who's name I forget, has a really good look, imo; a few beads and some feathers, and she would fit right into a "pirates of the carribean" movie - and thats a compliment! :)
    It would be great if names were listed in all descriptions for us viewers, and also so credit could be given where it's due...

    @DeFliegendeHollander Endothermic is where the reaction uses more energy than gained/given to break the bonds, resulting in a negative H value as it's absorbing heat from the outside. Just my interpretation that's likely to be wrong. I need to do some revision :P

  • @Volound

    @TheBetterGame indeed i am. it looks like the channel owner disapproved of my off-topic comment.

    If you reduce the temperature of your chemicals before the reaction can you mix larger volumes at a higher rate?

    How about manganese heptoxide? That stuff will oxidise any organic compound, producing great amounts of heat.

    @volound Although i don't appreciate censorship in any form, he was probably right to kill that comment. While i don't think you meant it in a mean way, it's easy for people to take a comment like that out of context and start a little comment war. However, i will reiterate that I still don't support censorship in any form.

    I wonder.... how do chemical reactions take place in the sun? I mean, since the sun is already doing a fusion reaction, and say there is allot of compressed high temperature fluorine that wants to react with something; will the fusion reaction be the first reaction, or would the fluorine react with something first, and then fusion would take place with multiple elements (or something else)?

    @HWGuyEG The fat person's circulatory system has to work harder to move the heat from his core to his skin's surface. So even if he's putting out the same power as his skinny friend, he still has to work harder.
