- Did you know that the energy change is the same if:
you throw salt into infinite water OR
break salt up into gaseous ions then threw those ions into infinite water!
Great - now throw yourself into (infinite) water!

Mr. Thornley,
You're he hero CaNTa deserves...and the one it needs right now
Love from CaNTa
Can't get more simpler thanks to you!
My guy out here saving lives video after video
thanks alot Mr. Thornley! 😃👍 helped so much!
Wow, this is so good, wished I found this sooner!
I have watched this video a handful of times over the past two years and I only now got the reference to Dr. Strangelove at the end... RIP me I have Paper 1 and 2 tomorrow.
+andrew hunter The other 2 sciences (esp. the physics which was so weird the head of IB mentioned it on her twitter feed after a petition) were odd exams. Lets hope the chem is not too different from past years.
06:46 ΔH°sol (CaCl2) not CaBr2. thanks a lot anyway!!
You’re awwwwwesome!
Hi Richard again in minute 6:50 you write CaBr2 and it is CaCl2. reGARDS
Mr Thornley, I dare to make a small correction of your beautiful presentation...
At the end of your presentation, you said STP was equal to standard condition. But STP is 0 Celsius while standard condition when measuring enthalpy is 25 Celsius hence not the same.
ok, i shall research this a bit - the IB STP is of course inconsistent with reality though - i shall check our holy books!
Can you explain to me what you mean by New Syllabus? Are you referring to the post 2016 syllabus or...?
New syllabus = first exams in 2016
Oh alright, thank you very much for your help!
what program do you use to do all of this?
gmod
Energy cycle? No likely. Energy flows, it doesn't cycle back to be used over again.
