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

📚 I made the mistake of buying all of my textbooks, I wish I had the option of renting them. Thankfully you do, with Chegg Textbook Rentals.

💁‍♀️ 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!

I love that you take the time to create quality educational content with a creative twist!

I swear to god this is way better than having to sit in front of a screen for three hours listening to a boring lecture, with a not so skilled lecturer that can't get the point across as well as you do! So thank you for making these videos and putting all that effort into them, they're short, simple, colorful, get straight to the point, and on top of all of that... your explanations are pretty clear as well. Thank god I came across this channel, I now know from where I'm gonna be studying chem. for the rest of this year!

Chemistry is so difficult and you teach it so that anyone is able to learn. You make it seem so much more simple and I love the creative editing it makes the videos so much more appealing and keeps me engaged. You saved my chemistry grade, thank you!!

OMG, I have a chemistry final tomorrow so any kind of help is appreciated. Thanks!

[politicalsquid]

Your explanations and methods of teaching are so clear I'm just annoyed I hadn't found your channel earlier. Thank you so much for the effort you put into teaching and helping out others!❤️❤️

[niroos]

its a pleasure to watch your videos
so easy to understand and purple is my fav

[thedukeofearl]

Probably the most succinct Hess's law video (pertaining to this type of question) out there. Gracias.

[fatimaghulam]

God bless your soul. Your teaching is so simple and helpful!!

[jennyliu]

the legend herself!!! you are so good. i thought i was super bad at chemistry, but you explain it so well!

[Reckless-Rin]

THESE VIDEOS ARE SO AMAZING😭 PLEASE CONTINUE MAKING THEMM 💗

[KennedyMalisawa-yf]

You are the best
You really make chemistry look simple 💯

[marisayvonne]

Thank you for making something seeming so complicated really understandable. So grateful for your channel!

[jihongrim]

love the color of this video! of course it was really helpful!

[stanhelton]

This really bothered me until I substituted a letter for each molecule. The subscripts must have overwhelmed me where I couldn’t figure out the math for problem.

[dharmasilansilan]

I couldn't understand this for the first time i saw the video but still i love the way you teach

[jumbojumbojumbojumbo]

Mam your teaching is brilliant, I could not thank you enough

[Ethherr]

Or you can divide the first and third equations by 2 and you'll get the enthalpy of formation of NH3, CH4 and HCN.
Then you can use ΔΗ= Σ ΔΗf(products) - Σ ΔΗf(reactants), anyway great explanation and video!

[lancegelman]

Your videos help me do excellent on exams. Thanks!!

[melanyleal]

Tomorrow is my final and you just saved my life, thank you<33

[rishikashah]

First video I've watched of you and what my teacher couldn't explain in 3 classes, you explained in 1 video! such a creative and easy way to solve them, tysm! <3
