Time to speedrun and learn the whole semester for the finals
Sahi pakde ho online exam OP!!!!!🙄🙄🙄🙄😉
Learnt this last week forgot already now im here
@@puretestosterone2373 learned today, forgot today, hw due in an hour
Me rn. Finals in like 4 weeks and I've slept through almost all my Chemistry classes. Hehe... I'm in danger.
@@datboi1861 good luck👍🏾
cant thank you enough for doing these videos. i have a terrible teacher and these videos are how i actually understand the material!!!
Literally took the words right out of my mouth😂🙏
@@samyentertainment3086 +1 😂
Same
me too my teacher sucks
On #5 you used 120°C instead of 90°C for Iron. Hence, the final temperature is 44.5°C, not 48.6°C. Moreover, thank you ❤🙏 for your videos, JG you're the best tutor I have ever heard.
Im glad im not the only one that got that
That is what I got tooo
i noticed that also he used 120 instead of 90
okay thank u thought i was going crazy lol
frr spent almost 20min trying to figure out where i went wrong lol
My college chem class is taught by a short lecture and "activity" handouts which are supposed to teach us everything we need to know on the subject. No matter how many times I read them I just couldn't retain that information, I felt so frustrated until i found your videos. I went from feeling horrible on my chances for passing the class to getting A's on my first two exams. Thank you so much for making these videos.
Andrew Buchtan then I’m probably not supposed to be doing this in middle school
xd Fortnite you’ll understand when you’re in college
im ALL ADVANCED AND ACCEL IM SMART
In my college classes so far they just throw shit at you once, then expect you to know it all from there on out
I'm in the same situation. I feel like it's extremely sad. Basically the guy who runs this channel is doing my professor's job for basically free while the "professor" does nothing. We pay like 10k a semester, it's very disturbing.
67.5*-90 not 67.5*120
the final tem should be 44.5degree cel
but the video is amazing...thanks!!
the mistake at 23:50
I was just going to say that!
i feel like the answer is 43.02938 degree cel . Correct me if im wrong
Kept reworking it thinking I had made a mistake thanks
@@MJ-wj5er I think the answer is 44.48
Thank you, for a second I thought I was trippin
You getting me through sophmore chem
He is getting me through Freshman chemistry.
Kiara Tucker he is getting me though pre school chem
He is getting me through senior physics
he is etting me through freshman physics
getting me thru 8th grade physics
Who else is here because they're hella confused on their assignment. (Here during Covid)
lol me
My book problem says 6.2 liters of water but i need to use grams. What do I do
@@josuegonzales8037 6.2L x 1000g
@@symfora1495 thanks
Here🖐
Schools during COVID isn’t the move
Facts i really thought taking AP classes during COVID would be easy😭🤡
Really is bs
fr :/ ion know what’s going on half the time
Yep 😭
@@ravenjwls55 AP CHEM & PHYSICS AND IM FAILING BOTH RN😭 after taking IB chem & Physics
Thermochemistry HW due October 18, and been struggling so much. Thank you for providing this lecture, as you teach better than my own chemistry professor
By far the best teacher I've never had. This world needs more people like you!
Your videos help me study, and you explain these concepts so well. TYSM!!
Hi. Just want to clarify problem #5 about the Aluminum and Iron initial temperature. It seems you calculated 120 degrees Celsius for Iron instead of 90 degrees Celsius only. Thank you, pls review also the final temperature happens to be the final answer too. ☺
I saw that too. It was driving me crazy
Thank you 🙏
Any who got replay
Yeah i got 44.5
I got 44.4
Great Video! Super helpful! Just a slight comment on 8. There is a small error for the initial temperature of Iron metal when plugging into mCdeltaT. You put it as 120 degrees celsius when the question says the initial temperature was 90 degrees Celsius. Anyways, the method and step by step process is pretty much spot on though! Thank you again!
I thought I was the only one who noticed! lol
Which means I got it
Thanks
mods I thought i got it wrong
thank youuuuu
thought i messed up for a bit there lol
Thank God for this comment
Just wrote my chem final for the semester
Got a great grade for the first time
Very grateful
👍😍❤️
there was a mistake in the video at 22:45 he gave both metals the same initial temperatures whilst they were different the aluminum had 120 and the unknown metal had 90 he put 120 for both.
Yeah, noticed it too. I thought i was wrong after i had a different answer. So i went back to check and saw the error. But thanks to him for all the help. We all make mistakes sometimes
I got 41.7975. That would be correct?
@@cruzgonzalez3863 I think the answer is 44.484
Its 44.484, but you can try it again
Ive got 44.48
I just have to thank you for these videos because they're saving my life right now.
I'm glad you found it useful.
THANK YOU SO MUCH, my teacher is a good guy and all but I struggle to learn anything. I can't tell you just how much this helped
Bros nose is permanently plugged
yeah so like i dont get it
Might wanna look at some exaples of problems like thisnon the internet and use this vid as a step by step guide to solve them. Really helps getting the process intonyour head
Increase your iq

You are glorious, thank you for the amazing videos, you've helped me so much through Pre-AP chem.
Your videos are amazing. Three years ago, you helped me pass an online Algebra class and now that I decided to go through hell again, they are carrying me through Intro to Chem. The lecture videos given really aren't lectures and the book doesn't seem to explain the numbers given very well. Cannot thank you enough for making these.
You teach this so much better than my teacher. Thanks for helping me study!
This might be for chemistry but I'm using this for my physics exam coming up. So helpful.
me too!
Same here 😂
Omg I forgot this is chemistry but I'm learning it for physics 🤦🏻♀️
@@nerdly1363 yep. me too
uh be careful. some equations could be different for physics such as change in energy = q + w (in chem) but q - w ( in physics)
To my fellow watchers...
Error in 23:22
It's actually 67.5(Tsubf - 90), not 120.
:)
Yes!
and the answer would be 44.42C

really
Professor Organic Chemistry Tutor, thank you for a lengthy video/lecture on Specific Heat Problems and Calculations in AP/General Chemistry. The practice problems are awesome from start to finish. Each problem increases my knowledge and understanding of Specific Heat Problems in Modern Chemistry. Professor Organic Chemistry Tutor, thanks to the viewers for finding and correcting the error(s) in this great video.
You are the best! Thank you for these videos! You saved me in Chem and calculus!
Thank you man, it helped so much.
I just wanna say thank you for saving my life!! you really don't under how this video saved me, like i went from a 20 percent confidence rate to a 99 percent!! God bless you richly!!
Omg my chem teacher just displays her notes on the board and tells us to learn it
This was the best video i have ever seen on this topic, Thank you.
Thank you for making these super helpful videos!
Please guys any time a mistake is noted, please correct them in the comment section, don't insult or downgrade. Thank you
Organic Chemistry is the best school I've ever had. Thank u for giving me insight in physics and other science subjects.
I love you so much. My instructor gave us questions with new symbols and letters and no explanations, so I hit up google + youtube and found you: my savior.
So good! Thx a lot for your videos!
Thank you so much for this man.
I feel like mark wahlberg is teaching me chemistry
casper johnson He does sound like Mark lol
casper johnson haha! Yessssssss
I always think the same thing. Iol
C Johnson lmao - hilarious
Hey! Great stuff! Much appreciated! Here is to getting a good grade!
This is a blessing from heaven
This guy really doesn't know how much he's saving my academic life 😭❤️
Thank you very much. Tomorrow is our exam now I learned many techniques in solving this problems.
This channel is the only thing helping me in my chemistry studies......owe you a lot sir....❤
thank you i was crying over chem homework i didn't understand and this helped break it down really well
you're the best physics teacher ever!♥♥
Thanks for the explanations, it helps me with my tutorials..
You are 100x better than my professor and it is all free to learn.
hello.
one of the question result for the final temperature of mixture becomes 44.48 c
anyway , useful
thank you
Yes agreem exactly the same
This has really helped me a lot ..you have no idea 😩👌
In the aluminium, iron and water example at 22:07, I think that iron had the initial temperature of 90 C but then you took 120 C afterwards by mistake.
Hey, I thought the same thing.
yeah same here I wonder why that happen
Yh I just saw that too
Had the same thought. I thought I was tripping man
Thanks a lot Sir. Your videos have been helping me entirely to better comprehend and standout also in class. Thank you a 3000
Thank you very much, It helped me a lot
Vividly explained. Thanks a lot.
this was so so helpful, thank you
Really helpful, just sometimes have problems following the dude because he often doesn't use things like °C or grams but rather only the numbers
Eventhough you made a mistake in the excise involving Al,Fe and H2o at the level of the initial temp of iron, am very thankful for your help althrough
for the iron metal you should use 90 as the initial temp. But still, everyone does mistakes. I love your videos and they help me so much. Thank you. Plus all the people who comment noticing that mistake get it because of you so stop being mad people. He is the one who got you to understand so much that you can even catch errors now. That's a reason to be happy. Cheers.
I love you, man. Seriously.
thanks for the lesson!
tryna get through honors chem as a freshman during covid 🙏
Thank you sooo much for this video
You are amazing! Thanks alot
you are a life saver
thankyou so muchhh
this has save me literallyyy!!!!!
Thank you 😭🙏 this is getting me through freshman year chemistry 😪
this was super helpful
Not gonna lie, you saved me during quarantine, these teachers be making me write 50 slides worth of notes and give a brief explanation and don't explain the process on how to do the equation. Now give me a kiss. 😘😘
*Kiss.*
Don't know if you'll see this but you do a great service to the college chem majors
Thanks for your prepared by this lesson is very nice and good Example.thanks
Thank you!
great video! how would you manipulate the equation if you are solving for mass? thanks!
sir, you are doing God's work. thank you so much
You my good sir are a god send.
master chief, THANKS!
thank you very much , you were very helpful but I hope that you have noticed the wrong temp. of iron
love this
You're the best ❤
Ahhhh I actually understand it thank you
this dude is 2 good bro!!!
Thanks man
Ahh yes...I need this for life's journey.
thank you so much. GODBLESS.
Thanks Alot from your videos .❤❤
Dam I got the NYS Regents exam tmr, can’t tank you enough 🤗🤗
Did you pass?
listening to organic chemistry inputing his numbers on the calculator is so satisfying.
I have an exam in an hour and this video is helping me out
Thanks so much bro
nice video very helpfull
23:43 I think he was wrong on this part because the given initial temperature of iron was 90°C but he uses 120°C instead which is the initial temperature for the aluminium but other than that great video
Yes I noticed that too....and Tf was 44.48°C
THAT'S WHAT I NOTICED
4 hours before my exam, and I feel like I'm going to pass it. THANK YOUUU!!!
How'd it go?
@@datboi1861 He failed lol
@@ng7756 💀💀💀
you're a savior
theres a slight error at 22:11, it should be 67.5(T-90), but regardless of that, great work
Thank you !!!!!!!!!!!!!!!!
thank u sir....💐
good one there
My duded here saving future career lives
thank you king
You are legit saving me on my physics exams. Thanks :)
God bless you sir 🙏.
Was hoping you would pick up on your mistake at 23:50 but since you didnt....
It's 67.5*(Tf-90)
My answer was was Tf= 44.47°C
I also used Kg instead of g.
And my C for H2O was 4186J/Kg °C
Happens to the best of us chief.
Thanks for your unconditional tutoring 🙏🏽
