Your work is excellent. I have used a few in my classes. I just noticed that you reversed the signs on all the terms in your last quadratic by moving them to the opposite side. Wouldn't just rearranging them on the same side work too?

this channel has quite literally saved my genchem grade so many times. thank you for making these videos i kept looking up how to do this question for my homework but none of the examples online used the numbers i had to use and the x's were confusing me so bad. but this video actually helped me understand how to do it myself thank you!!!!!!!!!!!!!!!

Something about her voice and the way she explains these concepts is so reassuring... Like wow, maybe i can understand this... lol

[@ada3360]

I really really appreciate all your dedication and hard work that goes into these videos!!! just soooo brilliant!

This is the most useful video about chemical equilibrium I've watched so far.

Dutch student here, you were so much more clear than the dutch help videos. Tyy

[@jakefarr6661]

This was super helpful and well explained. Thank you!!!

[@malsa5683]

OMG, thank you soo much. I am uni chem 115 and as usual, the prof didn't go step by step on how to do it. I had forgotten this. Finally, I understand. Thanks again I wish I would hug you through the screen ❤️

[@kimlove3040]

thank you so much for this, i was never ever good at algebra and this broke it down perfectly. I appreciate you!!!

[@dieded392]

Thank you! This video made the steps more understandable.

[@chanellemariedentalmentor3107]

So concise and easy to understand

[@fangirlxlyrics360]

My professor decided to skip most of these steps and I couldn't understand how he got those values. Thank you!!!!!! My midterm is on equilibrium and I might pass now lol

[@holyknighthodrick3614]

Very nice way of presenting, high quality

@melissameribel could you please explain how do we get moldm‐³ as the final unit for the following reaction? I have tried every way to sort it out but don't understand how we get moldm‐³ . Will be really thankful for your help. Q.When nitrogen reacts with hydrogen to form ammonia, the equilibrium mixture contains 0.31 mol dm‐³ and 0.50 mol dm‐³ of nitrogen and hydrogen respectively. If the Kc is 0.50 mol‐²dm⁶, what is the equilibrium concentration of NH3?

I am super rusty on the quadratic equation, so maybe this is just me other thinking it…but on the second example, I don’t understand why the signs are switched. After you subtract 4x squared to get 21x squared….why to you flip the signs?

Yes sridhacharaya rule. Feeling proud😎 to be indian. I also study in class10..

[@yashmadavi5190]

Thank you so much 😊😊

[@wanseefan3325]

very helpful. Thank you

[@benbranca]

you are the only reason I am going to probably not fail chemistry thank you omg

Hello, what program/website do you use for your thumbnails, to cut your image out of the background and put the white border around yourself?

[@melissamaribel]

I use photoshop but if you google background removal tool there’s other ones that are faster

[@tubbanivanne5444]

How did you get the concentration for [HI]?

[@ariellewhite739]

You explained that very well thank you #subscribed

[@trends-07]

thank you 😭

[@plurz4342]

how do you do this method if they give you a volume aswell?

[@yas8813]

Amazing

[@farmerboone4.0]

saved me again

[@natashariley9226]

Thankyou for your videos. I found you post summer class. Are you available for private tutoring online?My Daughter is taking Chemistry 2 for the 3rd time. Finaled the final on Thrusday 8/13/20. She is devasted.

[@melissamaribel]

I’m sorry but I’m no longer tutoring

[@natashariley9226]

Thankyou Melissa for responding. . I will keep watching your videos. Very helpful. Greatly appreciated. God Bless You. 🥳

TIL how to do this (in grad school)

[@satyamanand1713]

Being a CHEMISTRY students this gets very daunting sometimes 😐

[@jameshopkins3541]

TOO MUCH DETAIL

[@oliyana9924]

You are so beautiful girl

Saved the day again. Thanks so much
