Hey, this is a really intuitive way to study. I like being able to see other students struggle but begin to figure it out. For some reason it helps more then someone just saying "do this, then that" etc. Is there someone you could do this with stoichiometry? I still seem to struggle with this even though by comparison I'm in a high level chemistry class. I understand things like thermodynamics, polymer addition, liquid crystal's various state of matter, etc. but I don't get basic stoichiometry! For some reason, there is just a disconnect for me.
I wish you were my chemistry professor, you explained everything so well and you really helped me figure out how to solve gas law problems.. Thank you so much for sharing, I'm grateful I found your channel.
Melissa you have the most creative way of helping people through your creative website design. Few years ago you made such an educational impact on me. Wishing nothing but the best.
I just started watching your channel and before, I have gotten below 70s and around 80's on my first semester of honors chemistry (Ended with a B). Now, I have gotten a 94 on one quiz, and it is starting to click. You have taught me so much. Thank you for all you do :)
So helpful, I tried to solve the problems along with Melissa in the past video and was able to understand the problems and formulas. This time I was trying to write out the problems in my head and had no problem at all. Thank you so much 🙌
Need more practice with gas law questions, partial pressure questions, finding the molar mass of a gas and so on? Breathe I got you! My step by step notes will help you out ➡️ melissa.help/gaslawsnotes
you are really helping us out melissa, i like that seems like we are going to work together during the holidays. thanks god i have a you tube tutour now.
Hey melissa! I'm from Pakistan and great fan of you.Your videos are a great help for me and I easily understand the topics through your videos.plz keep making such videos to help the students get through this subject😊
Hey Melissa I have been having some trouble with organic chemistry and wanted to download your guide but i haven't signed up to your website. Could you please guide on how to sign up, thank you
Love you channel! Have you ever considered doing the SAT Chemistry Practice Tests. There are two of them (by the College Board). This would help me and so many others!
A 5.00 L air sample has a pressure of 107 kPa at a temperature of -50.0 C. If the temperature is raised to 102 C and the volume expands to 7.00L, what will the new pressure be?
Hi dear, First of all I would like to thank you from the deep for the lessons & topic which you covered in last many lectures, amazing and easily made out, once again thanks. I'm an Engineering student, there is a topic of fule consumption and fule combustion, need your help to understand how we calculate the same individual and how would we determine flue gases? Hope to get a positive response.
Correct me if im wrong ma'am but the woman made the wrong coped(in the lower part) it should be 280.9917355 NOT 280.991735.and secondly ma'am where did the girl get the 273?. Hope you will notice me. Thank you!
the 273 is the amount she subtracted from their final answer because the answer should be in Celsius! The conversion of Celsius to Kelvin is +273, so to get back to Celsius (Kelvin --> Celsius), you'll have to -273.
n=14.007 g/mol h=3x1 g/mol adding em up will result in 17.007 g NH3 if you are confused why we multiplied the molar mass of hydrogen by 3, we did so because there are 3 hydrogen atoms in NH3 for an individual element, atomic mass= molar mass, you can simply find molar mass of individual elements on periodic table known as atomic mass
just refer to the periodic table and see how much the atomic mass of a certain element weighs, for example, N molar mass is 14.01. And let's say if you wanted to find the molar mass of a diatomic compound like H2O; 1)you have 2 hydrogen atoms and 1 oxygen atom 2) from the periodic table, hydrogen has a molar mass of 1.007 g/mol and oxygen has about 16.00 g/mol 3) do the calculation 1.007(2)+16= 18 g/mol, and this is the molar mass
Sis I gotta say-you are the only reason I passed chemistry this year. I just took my final and I did good 😊 I’m so grateful
Yay!! Congratulations Anna 🎉

this came out literally a week after my gas laws test 😭😭 but this helps me understand it much better

Melissa because of your videos I got an 84 on my final!! I can't thank you enough, you've helped me so much!
Waiting out my final grade in chemistry. Looks to be a pass again. Thanks once again Melissa!
You're very welcome Derek!
@@melissamaribelwhat application are you using for the virtual notebook?
Tysm!! I have a unit test tmr and I found this reallyyyy helpful!!!
I appreciate you & your videos, you've been tremendous help. May god bless you always!
Chemistry Final on Tuesday. You’re saving my life!!!
I have a test tomorrow and this video, it's EXACTLY what I was looking for😭💕

definitely keep doing these please. These are most helpful
Your teaching style is very creative. I loved it !
Your videos are so helpful!
Chemistry questions are just AWESOME
Thank you this is so helpful!

This video is great! What app did you use? Because I love the idea that you both could write on the same screen!

Whatttt my favorite youtubers together??? YES
💕💕
wait who the student?
thanks, it was a really good session,I had no interest in chemistry but now I am really hyped about chemistry Thankyou
THANK YOU SO MUCH!!
i wish i could have a tutor like u melisa

Hey, Melissa Can you please bring some organised Course on Physical Chemistry For JEE ADVANCED LEVEL EXAMS?
What app do you use ?
Love you melissa💞
💕💕
Mellisa plss i dont really understand this mole gram stuff, could u please do another video on converting grammes to moles and vice versa
does this whole course apply to ap chemistry? like does it cover those topics?
Hey, what app are you using?
thank you very muchhhh
very helpful
You’re welcome 😊
My school teacher has taught us to convert the mL into L first because the volume is always in litres. So, I got a whole sort of different answer.
Correct me if im wrong ma'am but the woman made the wrong coped(in the lower part) it should be 280.9917355 NOT 280.991735.and secondly ma'am where did the girl get the 273?. Hope you will notice me. Thank you!

@ 23.07 how did she get 17.031g? I’m confused with G to Molar Mass Conv. Someone please explain this.
n=14.007 g/mol
h=3x1 g/mol
adding em up will result in 17.007 g NH3
if you are confused why we multiplied the molar mass of hydrogen by 3, we did so because there are 3 hydrogen atoms in NH3
for an individual element, atomic mass= molar mass, you can simply find molar mass of individual elements on periodic table known as atomic mass
you are the BEST!!!!
But we have to take pressure in atm na means divided 760mm hg because 1 atm =760mm hg
Press the up arrow on the TI-30x calcultor to go to your history
Thank you for this session. I can also relate and enjoyed solving the problems that have shown. Salute ❤️ hope that I can also be that girl hshshshs
Can please explain "le châtelier’s principal"
Ma'am where did you get the 273?
Kelvin
how to get molar mass?
just refer to the periodic table and see how much the atomic mass of a certain element weighs, for example, N molar mass is 14.01.
And let's say if you wanted to find the molar mass of a diatomic compound like H2O;
1)you have 2 hydrogen atoms and 1 oxygen atom
2) from the periodic table, hydrogen has a molar mass of 1.007 g/mol and oxygen has about 16.00 g/mol
3) do the calculation 1.007(2)+16= 18 g/mol, and this is the molar mass
what if melissa & tyler got togetherrr😱❤️❤️
To make an epic video series 😂
life saver
Melissa, her answer @ #2 is 0.0313 atm… isnt it 0.0313 mm Hg?
It’s 2024 and I’m still watching.❤❤❤❤
It's 2024 and I'm still teaching chemistry 😆
but i think she can cross multiply instead of she multiply both side by T2
What grade is this?
This applies to both college and high school levels
Which country are you from??
you look just like Ana Golja
I’m sorry but how the end got me confused
