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
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.
@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 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)?
so, if i don't have a furnace. I'll use the calcium oxide and let it react to the water in the beaker and drop the beaker to a pot of water and wait for it to boil.
I read the description below the video (What is an exothermic reaction?), and I thought it was the first comment. Then I wondered if that person had bothered watching the video.
@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.
"Your fat friend sweating like a pig" ..I cracked up so hard watching him say it.
such gold.

"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!

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

@BornXHated That screensaver is awesome. He talks about a bang and it changes to red.
I would travel from Australia to Nottingham just to see this genius man.
"your fat friend is running around like a pig"
oh man, made me laugh...
...I think I am the fat "friend"...
Where is my comfort food?

@TheBetterGame indeed i am. it looks like the channel owner disapproved of my off-topic comment.
He is wonderfully frank
If you reduce the temperature of your chemicals before the reaction can you mix larger volumes at a higher rate?
@00gir00 That's no screensaver, that's the one-pixel version of Tetris.
Thanks to these videos im gonna get higher grades in school. Thanks Brady :D
@talshiarr CaO + H2O -> 2OH- + Ca2+ which then forms Ca(OH)2
@cazybeast2 the professor's hair is a big bang.
Best Channel!!!!!
How about manganese heptoxide? That stuff will oxidise any organic compound, producing great amounts of heat.
I love this guy. I wish he was my chem professor.
My chem professor talks and talks and I think she gets lost in her own head
a bucket of anhydrous copper sulphate and water would have been a good example too, if you don't believe me try it with your hand on the bucket :)
@YamiPoyo No, it's a base.
Excellent video.
Please make a video about Sulfurexafluorid.
Professor changed the dual monitor screensaver, i think it used to say "Green Chemistry!!!" and bounce back and forth
@YamiPoyo although this is Calcium Oxide :)
I love that you used a 'fat friend' to illustrate surface area! My science teacher is way to PC to ever do that! It made me laugh hysterically!

ROFLOLMFAO @ 1:40
Go, Professor, go! XD
Is this the same stuff they use in the heaters in the US Army rations(MRE)?
wow, thats a badass screensaver :P
Prof's hair looks particularly wild today!
@RockMedved Good point.
my-face-when "just feel your body - it's warm, it's warm 'cause it's an exothermic reaction"
Woo view number 2! Love your videos.

The professor is so cooooooooool.
"Your really fat friend is running around in a T-shirt saying it's too hot and sweating like a pig!" HA HA HA that's me!
Yay for learning!
As someone who overheats easily and is not obese or overweight, I am mildly offended at the Professor's analogy. ;)
thanks
So let me get this straight, if you mix them to fast. You create the universe? Keeewl.
Why is the room temprature so low in your lab? 5 degrees more and it would be confortable!
I was totally eating some Kettle crisps when the prof mentioned crisps hahah
Magic. Got it.
Was this video posted on minute ago?
0:22 - I so totally thought about the guy from Police Academy. Many, many, MANY....
so, if i don't have a furnace. I'll use the calcium oxide and let it react to the water in the beaker and drop the beaker to a pot of water and wait for it to boil.
I think I am in love with Ms Tang
I read the description below the video (What is an exothermic reaction?), and I thought it was the first comment. Then I wondered if that person had bothered watching the video.
We did this in class today
...Only the professor can use the words 'fat friend' and 'sweating like a pig'. He is the only man I won't punch for using those words.
@fr3d420 huh? it was nearly 5 minutes long. what's spam in it?
"Half a beaker" totally scientific measurement.
@cazybeast2 Or more likely by a physicist.
Is calcium hydroxide an acid?
His hair is back to being unruly!
"your really fat friend is running around in a t-shirt, saying "it's too hot" and sweating like a pig" haha
"pleasently warm" thats what she said
@ChipsASensation
I don't either
I didn't get the thing at 1:06, could somebody help me out?
@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.
burning oil.. in our bodies... wait does that theoretically mean spontaneous combustion is possible?
@TheIronTank join the club=D
you guys leave the screens on in the background on purpose don't you?
Someone do a sound bite with 1:40 - 1:54
@YamiPoyo Base
Colour changing screen at 0:11 !!!
BYMCKR no green :(
In soviet russia fat friend makes you sweat xD Best comment of the video with the fat friend xD
interesting.
my fat friend is sweating like a pig. LOL. To hell with correctness. Love the guy!
That screensaver is really distracting
"...and is sweating everywhere. like a pig."
Im fat, and I laught hard.
This never actually occured to me :-D
that is how smart people screen saver
Anybody else from the age range of 14-17 Finding this tying in exactly with their revision times?
:D
2:00 yay german.
@oisiaa Or it just caused itself.
I can't concentrate on what the prof is saying because of the colour changing screen
the example of the fat friend made me understand better
@ChiefDen4 :D
@periodicvideos if the friend in question is fat enough for the difference to be noticeable then he will not, in fact, be running
Your Screensaver is gonna give someone a seizure.
How does Prof know that I'm skinny like a twig?
I wonder what would happen if my fat friend stepped into a beaker and I added some deionized water, would I see bubbles ? :-)
@ChipsASensation Lolol
Does that mean that skinny people are endothermic?
ha! she has 6 eyes!
i am that fat friend
I really like your videos but you should have some more respect for people, maun
@fkazuo24 nopes
I sweat like a pig! :D
because the fat friend´s surface area is much smaller!
@RBaleog lololol
First to say first
0:06 WRONG! Exothermic can give out any amount of thermal energy xD JK
@TabbytabtabOmega I watched every single periodic video except this. I can't stand the stupid colour flashing screen.
