Chemistry 1 Final Exam Review: ua-cam.com/video/5yw1YH7YA7c/v-deo.html
Thank you so much you’ve taught me more than my chem teacher ever has
An 11 minute video helped me out more than 5 chapters from my book
then you didn't read your textbook completely, I read the book and now it makes even more sense here.
I couldbt agree more
The book helped but not fully
It was like the book has 50 percent of the info (That I could understand) and this has the rest that makes me fully understand
On Jesus Christ
@@zynex9250 it's just to much verbiage in the book. Im a visual learner that way I correlate the symbols and make mental connections. Luckily I already aced the class. Amazing how some videos on youtube have better structure than actual instructors.
It's unreal how incredibly valuable these videos are and have been, especially over the last two years. You have not gotten anywhere near the recognition you deserve for putting so many hours into making these subjects accessible for everyone.
my teacher makes things unnecessarily complicated in a long lesson, this explained the concept in 10 minutes and I aced the exam, you're literally a god
No he is not (Jesus the lord)
@@urrelative6961
Aint jesus the son of god, why do christians not even know their own lore
@@urrelative6961 why do christians take comments like "ur a god" so literally.
I studied before lecture and my instructor mention things that was’t really worth mentioning. I could explain it in a few sentences while she was going into detail for each step. Great instructor but other students were left confused.
All we need is the formula, and a little guidance. no need for fancy words or background history. Just need to be nice and simple. By nice, maybe have the conversions placed separately instead of writing it next to the formula.
@@emilyo8365 idk maybe because the person did say "literally"
i’m literally watching this taking my test and i have 8 mins left to finish
me too😭
LOL
Same 5 minute left to begin test. 😅😅
LMAO SAME
It’s alright champ
0:20 - Wavelength of a photon that has Frequency
2:50 - Frequency of photon that has Wavelength
4:13 - Frequency of photon that has Wavelength
5:40 - Wavelength of photon that has Frequency
6:55 - What happens to Wavelength as Photon Frequency increases?
7:37 - What is Frequency of photon with Energy
8:59 - Wavelength of a photon with Energy
Chem midterm week, this helped a lot!
Thank you h*ntai protagonist
yes i found the man
U a real one, thanks
Ty!!
For anyone who is stuck on how the they get 10^14 from 3*10^8/350*10^-9. Do 3/350, the answer is 8.57* 10^-3. then do 8-(-9)=10^17. simply add them 8.57*10^-3 + 10^17= 8.57*10^14.
I know this is a year late but thanks bro
@@riss5566 but where did he get 10^-3 from?
Thank you 😊
@@henry.-.2183 Idk if you still needed help with this, but the 10^-3 is there because when you do 3/350 you get 0.00857. So you need to move the decimal over three places to get 8.57 hence the 10^-3
thank you
I have a quiz in 5 minutes wish me luck y'all
Edit: A year later I find myself taking O chem II over the summer and am currently dying wish me luck
how was it? I have a quiz on this tomorrow :/
:D Crafting Magic 26 I have it tmr too😭the exponents confusing
Asvp Rvsa I just took the quiz and it was ehhhh,lol. Good luck
good luck
Damn I have a quiz tomorrow and I'm trying to memorize these equations cuz imma have to memorize lol wish me luck
I love this guy I was in class the teacher asked me how I’m going to figure out these light problems for tomorrow and I said the Organic Chemistry Tutor and everyone in my class started laughing😂
7 years later and your vids are still helping people each year. My AP chem teacher briefed over this once in class, and now our test including this is tomorrow. Thank you so much for these videos covering chemistry in such an understandable way :)
Taking chemistry online is insane. Thanks for making it all make sense to a visual learner like myself!
one thing I learned from this video
my teacher doesn't know what she's saying
Fax yo, my teach gives out a whole 40 minute video and I fall asleep half way through
Super helpful!😭 I pray there be continuous blessings for you and your family for generations!🙏🏽
This dude is legendary when it comes to online school
I don't learn from my professors. Instead, I learn from this channel. Thank you!
Your videos have made it so much easier for me to understand chemistry. I have one request. I can barely hear your soft spoken voice even when I turn my volume all the up on my laptop. can you maybe turn up your microphone so I can hear you louder? thank again.
I've said it before but I'll say it online. People learn at different speeds. And I can't stress enough the satisfaction of being able to pause my "teacher" when they say something like "okay solve this" to work it out best I can and then unpause them. As in my head I see my "teacher" getting the satisfaction of continually telling the subject to the best of their ability without the need to slow down. As at any moment I can pause or just use my left or right arrow key to go back and forth. Gods what an era we live in.
Professor Organic Chemistry Tutor ,thank you for a solid analysis and explanation of the Speed of Light, Frequency, and Wavelength in General and AP Chemistry. Chemistry is used in all walks and phases of life on planet earth. Frequencies and Wavelengths are well known concepts in radio technology. This is an error free video/lecture on UA-cam TV with the Organic Chemistry Tutor.
Your videos always clearly explain the ambiguous steps that I need spelled out! I'm so grateful for you and for these videos, I really appreciate them!!
I forgot to do my homework in physics yesterday but because of you I can pass just right now. Your a solid teacher. Better than my teacher though... Thanks a lot💞
THANK YOU SO MUCH! I bombed my first chemistry exam because I was so confused. Thank you for breaking down these equations!
Thank you so much!!! My teacher didn’t bother to go over it twice, now I understand it ty
YOU SAVED MY BEHIND IN MY CLASS SIR THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
This really helped me as a freshman in highschool, ty.
One thing I’ve learned from this video is UA-cam will always teach u better
You made chemistry very easy to understand!
I always come back to your videos
When I'm confused.. You are gifted man🙏
This
Was possibly the most helpful video I've ever seen in my life. Thank you omfg
This is incredible. This video, just like most of the others ive watched here has explained more in 11 min than my text book or unresponsive "mentor".
Right after chem class, when I’m doing home work, or when I’m studying for a chem test. I’m always watching his videos. 😭🙏🏽
best chem review videos on UA-cam
your channel in my opinion, is the best educational channel
This guy has helped me more than all of my teachers
I've understood more in this video than what my teacher taught us. Thank You my good Sir
Sir thank you for being alive, you literally saved my grades :'))
I literally have a test in about three hours thanks so much
Whenever I watch a math video. "Generic letter = totally unheard of gibberish times "did you just swear at me?""
Which country you live?
how is a tutor better than college chem teachers
voice is so frickin soothing
thank you for this video. i am able to teach my son about this topic. Great work!
missed my class when we went over this you saved my life bro
Just got humbled from a quiz that Im pretty sure I failed so now Im here
You, sir, are a lifesaver.
You saved my grades🙏Thank you
for anyone asking how did he get the 10^-4 from the first equation, he minused the 12 from 8
thank you I was over here like... i got 10^20
Do you always do that?
I love your videos better than any college professor
i have an exam in one hour and half, this is very helpful
thank you so much! every time I search for a problem in my classes, you will be here.
Best tutor even prepared for my exam .....thank u so much
Thank you, you are a life saver it’s so easier to understand chemistry now
oml you're a much better teacher than my professor, tysm.
1:14 how did he get that little -4?
@@simpatiko6392 because with exponent rules when exponents are being divided you treat them like theyre being subtracted. So in this case 8-12= -4 (also if they're being multiplied treat them like you're adding and add the two together, but that doesn't happen in this example.)
@@oneattempt8029 thank you very much
@@simpatiko6392 ye, np
Leaving a note for the equation E=hv if you have to find V( frequency) you gotta divide and if you have to find E(Energy) you have to multiply
Thank you. I don't know if this two word thing can even explain how your video just vanished my headache that i got about 2hrs back trying to solve this single question from the past paper related to wavelength just thank you in loads 😭
Hei man you know a lot about chem, physics, and math. You should try to take the MCAT just for fun. You would get 528. Your videos are the bests.
Tanginaaaa! Kakainis ng module!
Pati ‘ko napapa youtube na
Brrt Brrt
Thanks so much for the one who explain how to calculate the photons of light.....
best teaching channel
Without these videos I would have failed math and science
i have a quiz today on this and this helped me more than my teacher
The Organic Chemistry Tutor is HIM
Thank you so much for this! It was incredibly helpful.
This vid helped me alot...i am writing physics exam tomorrow wish me luck..
the organic chemistry tutor you got 2.12 million subs so you have a lot of clout on your name you better be legit
He is
This has helped me 100% thanks alot
You are a absolute hero and I wish I could donate to you but im broke.
Your name is absolute wisdom
how did he get 14 out of 8 and -9?
When you divide 3 by 350 you get .00857, when you subtract the powers you get 17 (since 8-(-9) is 8+9). So you have .00857*10^17, but this is not in scientific notation. For scientific notation you need a number between 1 and 10, .00857 is below 1 so you're going to have to simplifiy it further. Move the decimal 3 places to the right and you have 8.57, and the power will turn to 14 because you moved right three times.
@@graces990 soooo cool!!
@@graces990 thank you
@@graces990 holy fuck thank you so much 🙏 🙏🙏🙏🙏
you're a great teacher thank you. these videos have helped me so much.
Who else is here with 10 minutes until their proctored final?
Who isn't? That's the real question.
This is exactly what I needed! Thank you so much!!
you are my life saver
super great, wish to know then all applied for example to build an UV-C led light.
This is better than the textbook that's supposed to teach me -____-
It's a great help to me as a student. THANKS
This helps a lot to me thank you ❤
nobody:
not a single soul:
rando in the comments of all youtube videos: who’s here during this pandemic outbreak?
Osm video sir your video is very useful for me thanks a lot for making this video
I have 4 chapters to study for my class tomorrow at 08 💔. These are my only hope
You are a lifesaver!!
You saved my chem grade
Thank you!! My husband and I are having a debate right now and this proved my point !! I win!!🏆
I'm not gonna lie buhh this video was very helpful
Hello! So at 5:32 you got 10^14 but how did you get it from 10^8 and 10^-9?
it works when u plug it into the calculator because 350 = 3.5E+3
Who is also watching this 2025
Thank you, legend.
This video teaches me better than my teacher did😐🤚🏼
thank you so much
Aggressive calculator clicking in the background 1:05
This really helped me alot. Thank you
Thanks for a bunches 👍
you saved my life
*THANK YOU THANK YOU THANK YOU THANK YOU!!!*
You helped me a lot.... Thanks man... You are great...
😮
Why do you have to move 10^-9 to the top when converting to nm 11:35
not me watching thhis and some students at my age obssesed because of the way he teach
Helped me pass a test thanks :)
I LOVE YOU THANK YOU FOR THIS
we love you man
Question: Do the various waves that come out from the sun come out individually ( radio waves. Microwaves, x-ray waves) or do they come out in a combined wave having high and low frequency rates? And how is it separated?
@Van Kaizer Doyola Lazaro What does it say? They come out as separate waves or combined waves that can be separated? Where can I find info about this, what us your book? Thank you😀
On a Ti-84 you need to use the EE button because EE mean 10. And you put in the exponent next to it.
Example for Ti-84:
3e8/2.5e12
For a Ti-34 you need to put them in parentheses like this
Example for Ti-34:
3x10^8/(2.5x10^12)
Your welcome 🙏
I thank you so much for this
Thank you 🙏🙏
watching this right before my chem final
