💁‍♀️ 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!

You have a talent... you can take a concept that takes a week of explaining from my teacher and hours of individual studying and explain it in the best way possible in a 10-20 minute video. Thank you so much for helping a struggling student 🤗❤️

When I did chemistry practice problems on youtube it seemed very simple since you can tell what you need to do from the title of the video. When I did online study guides would be lost. This video really helped break down the basics and helps you learn which conversation is necessary for the problem. Thanks so much!

[@upsidedowncity4096]

This actually helped me well you did and I thank you so much for this. Our chemistry teacher is good but in my opinion what makes it fun to learn more about anything is your sense of humor, basically learn to have fun with the subject and students. And you are like that so that’s pretty great I subscribed to your channel cause I found it very helpful and you actually have explain very well. We have a EOC test tomorrow 😰I don’t expect to get a 90% if so then that’d be a miracle but anyways I don’t mind getting a good grade and or above approaches I just want to pass. Once again I thank you for creating this, and I am now considering myself to be one of your new students here 😁. Be safe and God bless!

where did the 22.99 come from?

[@Earendel.l]

Hi can anyone pls anseer this
The balanced reaction is: CaCO. Should I assume that the mol is 3? becuase Ca + C + O are different from one another, or since they're bonded, it's just 1?

[@Julia-lw4kk]

just 1

[@kutlwanogratitude2969]

Hey Melissa. May I please ask why you used 28 grams of carbon monoxide instead of 58 grams? Are we not supposed to multiply the 28 grams by 2?

[@isabellagalang3308]

no, because you are adding the CO's atomic weight in 1 mole.

[@arslanmoghal5472]

Awesome 👍
Thank U

[@bleep8933]

Thank you !

[@josephbarro4222]

ahhh I am kinda confused at the part where I should put 1 mole or the balanced mole value. Can you help me with that?

[@isabellagalang3308]

I guess you put 1 mole when you are computing the molar mass because it's the atomic weight that's important there but you put the coefficient of the balanced equation when you calculate the mole to mole ratio.

[@juliasouza4457]

The AP chem exam is tomorrow, do you have any tips?

I want to purchase some of your notes, but not sure of the difference between the “all notes” bundle and the “AP notes” bundle? Are they the same?

[@melissamaribel]

They are the same notes, AP chem and a college general chemistry class cover the same topics. Feel free to send me your syllabus and I’ll let you know exactly which notes I recommend. Use this link: melissa.help/syllabus

[@Cinnamoroll_bunny1]

@@melissamaribel perfect I just bought the bundle and the flash cards 🤣 thank you SO MUCH for teaching all this stuff online! I was super happy to hear that you have organic chemistry as well I will def be joining u for that too!! I haven’t run across any physics or biochem videos though….I’m REALLY hoping you do those too (or will very soon, especially physics!!)
Please let me know if you already have videos and notes somewhere for those or if you have plans in the near future to put that stuff out. I am taking physics in either the spring or fall, so I could really use your tutoring on that it’s going to be soooooo hard!!
Thanks so much!

Alena Mahadevan the 28 is the molar mass of CO, using the molar mass allows us to convert grams to moles
