🙌 This was my go-to homework help when I was in school. Chegg Study is one of my favorites.

💁‍♀️ HI I'M MELISSA MARIBEL
I help students pass Chemistry and Organic Chemistry. I used to struggle with this subject, so when I finally graduated with a bachelor's degree in Chemistry, I became a tutor so that you wouldn't have to struggle like I did. I know that with the right help, YOU CAN LEARN ANYTHING!

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?

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

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!!!!!!!!!!!!!!!

@ada3360 3 года назад

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.

@jakefarr6661 3 года назад

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

@dieded392 3 года назад

Thank you! This video made the steps more understandable.

@kimlove3040 Год назад

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

@malsa5683 2 года назад

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 ❤️

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

@chanellemariedentalmentor3107 3 года назад

@holyknighthodrick3614 2 года назад

Very nice way of presenting, high quality

@fangirlxlyrics360 Год назад

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

How did you get the concentration for [HI]?

@ariellewhite739 2 года назад

You explained that very well thank you #subscribed

@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?

@maghanchodhrichndsrijhavas982 3 года назад

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

@morgananne1027 2 года назад

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?

@plurz4342 Год назад

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

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 3 года назад

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

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

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 3 года назад

I’m sorry but I’m no longer tutoring

@natashariley9226 3 года назад
