Enthalpy of Reaction

[@nicolefurze688]

some people say that teachers teach because they cannot do. that is a complete lie. teaching is an art and a gift. this man in the video has that gift and gives his art generously. most of my professors in college do not possess this gift of teaching because they are not aware that teaching is something outside of just being able to do what it is they "teach". and thus, they do not deserve the money i spend on tuition, but mr. anderson does.

[@vog-]

Very true, only a few teachers I’ve had could actually teach in such a way

[@samnoname2010]

If I ever manage to get a PHD I'm giving you half of it

[@912sonic]

LOOOOL

[@Z3ROWOLFHD]

u get that phd bro?

[@avira1d]

Did you get the PHD???

[@cocoarecords]

samnoname2010 he dropped out

[@jenspetter1454]

?? so did you give half of it?

[@Angie-no7qx]

Did not want to keep asking my teacher for help on this since she got annoyed so I went to this video and saved me thanks

[@alyssahoffman8855]

I like this more than Khan Academy

[@jennycarnie7804]

Lol I saw your comment on Khan academy's video and found this. Thanks.

[@alyssahoffman8855]

[@simplededication1945]

Me too👍

[@zenalc536]

you are a very good teacher. you deserve 1 million more subscribers .

[@m.moorthym.moorthy232]

Your wish came true

[@Kenzo_254]

You are a really great teacher. I don't take it for granted. Respect.

[@GM-cz9sq]

You explained this in 8 minutes and managed to help me understand this better than my Chemistry professor did in an entire lecture period!

[@blue-wing2071]

and i take this in grade 12 :(

[@francisgregoryku1689]

Warlock i take this in gr11 lol taking a test about this tom. I guess senior high is on par with 1st -2nd yr college in some aspects

[@liammarie1447]

I literally shed a tear because of this 😂 thank you

[@tanyay1073]

Thanks for making chemistry a little more bearable! 😂👍🏼

[@Noellexafael]

And u just saved me from my teacher thanks a million haha, i have been struggling to remember that but the way you put things into perspective is really helpful.

[@thierrytrevorbusinge8186]

"The Bozeman effect" has had a very good impact on me....THANK YOU A LOT

[@flieu9342]

I think it’s very essential to define the unit of the Enthalpy of Reaction. What does the per mol stand for? Without discussing the concept of the Extent of Reaction, you will never truly understand the Enthalpy of Reaction, and why the Enthalpy of Reaction changes every time you manipulate your reactions. Per mol means per mole reaction!

[@winterhuff1338]

This helped me so much . I’ve been watching a bunch of videos on this but I couldn’t understand them .i understand this very much .thank you

[@zanahmed9343]

thanks bozeman i got a 200 on my ap bio test because there was a 100 point bonus.

[@hobihobi1563]

i literally got a revelation watching this... thank you so much

[@ComandaKronikk]

when bozeman times'd that 2O by half i was like WHAT IS THIS BLACK MAGIC

The original dynamite was made from diatomaceous earth, and this is still the major component of the recipe. Several binding and stabilizing agents were later added to improve stability and slow the rate at which the nitroglycerin would seep out of the sticks and pool in the container. This is why dynamite must be turned regularly during long-term storage, or else it may spontaneously blow up. Dynamite sticks are wrapped in wax paper because the surface of each stick is always moist with seeping nitroglycerin. Dynamite is still used commonly by civilian farmers in the USA, so you may encounter some lying around somewhere. Old dynamite is extremely unstable without the proper maintenance procedures. Do not touch abandoned dynamite, call the bomb squad instead.

[@andrewchen861]

hi i love you mr anderson thanks for saving my grade

[@mquartz7547]

Great explanation, very helpful! Thank you so much for all of your videos!

[@riddhivasu.studies]

Thermodynamics is SUPER INTERESTING, but at the same time, sometimes kind of hectic to deal with 😂

[@mcnagi4246]

Yes, thank you. That was really helpful!

[@maryshabo6261]

It was literally perfect keep going ❤️

[@rxthezh]

Just to point out I think the reaction in yellow at 4:44 should be o2(g) instead of o2(s)

[@helishah6903]

Thank you Mr. Anderson

[@AyoItzMat]

Excellent video, very concise.

[@avira1d]

Sir, I am thankful for you.

[@jacobh1995]

Thanks Mr. Bozeman

[@oogalook]

Thanks for the great video! Very helpful.

[@anaslahrichi]

Is enthalpy related to entropy ? Does enthalpy fit in some thermodynamic principle ?

[@Bozemanscience1]

Enthalpy and entropy are related but they are not the same thing. I am currently working on an entropy video.

[@chrysik.5755]

anas lahrichi yes they are related through the 2nd therm. law: δq(rev)=TdS. If you try for any to states to go (reversibly and under constant pressure): then you end with dU=Tds-pdV. (But because p,V,S, T are all quantities that are functions of states that's why you can use it generally between any 2 states!) Now, using that ENTHALPY can be written: H=U+pV so dH=dU+d(pV)=TdS + VdP. (equation relating enthalpy and entropy) So H is a function of S and p!! Again only state functions!! And of course after this you can take the corresponding derivatives.... Saying dH/dS at constant p is Temperature.

[@m000mbku2]

in the first problem, why is the oxygen a solid? why doesnt the arrow direction change when you reverse the reaction?

[@Sialkotivloggers]

sir I got your all points but not in few seconds.sir really your all videos are great .I am from Punjab and not understanding English that's why.

[@nikan4now]

Great video. Can you please answer my question? With these diagrams, do they show enthalpy or purely potential chemical energy? My confusion arises from the following: In an exothermic reaction, we know that chemical potential energy decreases and for conservation of energy to hold, kinetic energy should rise (product molecules moving faster). But if we said enthalpy decreases there will be a contradiction because enthalpy is internal energy + PV (assuming PV change is zero) , internal energy ITSELF contains kinetic energy of the molecules, so how could overall enthalpy decrease (KE increases and potential energy decreases by the same amount)

[@tinashemuza8671]

on 5:12 you made a mistake on the target reaction, which has oxygen as a solid. secondly i didnt find it clear how you got the half oxygen on the left side while it was on the right. otherwise the video was awesome

[@jessecruz6241]

I love your videos sir! Thank u soo much!

[@meernahro7164]

extremely helpful 😀 keep up the good work

[@AchikaRozkuro]

I always had a hard time about this. Even after received it like 3 times in schools!! Thanks a lot!!!! >w

[@santino4486]

video was helpful, could you explain to me what emthalpy fusion is ?

[@divneet3474]

But isnt the literal meaning of enthalpy that the whole process occurs at constant temperature and pressure?

[@jokroast6912]

I have never seen these fraction superscripts before and they are hurting my brain.

[@CarineFrisch]

We can't see the target equation because of the transcript at the bottom of the screen.

[@JANxKylie]

Thanks for that. ive had a 3hrs chem class on that and i dint understand anything. thanks.. can u make a video on the cycle and how u can figue stuff out of that please?

[@suffixable]

Can i know what's the difference between enthalpy of bond and enthalpy of heat of formation. Thank you

[@marijngoes6580]

check your vid around 2m50. your diagram goes wrong for changing the reaction around (invert products and reactants). I think it need correction

[@rahulsurwase6627]

Thanks mr Anderson

[@eskilingemann1783]

[@whitewolfie]

Thanks! It was really helpful!

[@philippebouchard9093]

Little mistake during the 4th minute. The target should be O2 (g) and not O2 (s) Very good video however. Thanks a lot

[@adryanvalhallatier5259]

Why is the first target of oxygen is solid?

[@danmadefurniture]

thankyou sir , it was quite helpful

[@marijngoes6580]

Also you made a tiny mistake with the pahse symbol of oxygen. it is not solid, it is a gas

[@zerok7038]

Hello. Greetings from Austria. I have only one complain. Namely sometimes subtitle cover some of your writings. I guess it was added afterwards...
