💁♀️ 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 are my savior!! My chem slides didnt even mention this part and im paying nearly 1k for this class. Thank you for helping other students especially during this pandemic where having a one on one with a professor is difficult nowadays.
Jesus Christ is our Saviour
Need to find a better class I am sorry yours is bad.
Ikr!!!!! I have a short test on these tomoro
This was SUCH a big help!! Thank you so much!!
I'm sad that you don't have more views on this! Everyone needs to watch this video!
You're an amazing teacher, thank you very much for helping us all! :)
I commend you Melissa. I've never seen a youtube tutor take the time out to work with other people. You've definitely taken it one step further. And, in the process it helped so many more.
you've made this more clear. Thank you Melissa
Thank goodness for you! Helped me SO SO much! You are definitely one of the best tutors on CZcams!!
A very perfect way of showing the student solving the problem and as the student moves on, giving instructions. My students learned a lot from that. Not many have a youtube whereby the student is active solving a formula. Very very very good. compliment.
I can't believe this is free to watch, thank you so much!!!
Thank you so much for doing these! It is like getting one-on-one tutoring, and your student asking questions and you including your answers helps so much more than just someone talking at me the whole time. It is so nice. This is a lifesaver find on the internet for me!! xD
thank you!
Thank u very much, that helps me alot, this is the first time i understand why there are more than one Lewis structure for polyatomic ions.
THIS MAKES SO MUCH SENSE NOW THANK YOU
Some great stuff! very easy to follow along, thank you very much!
You saved my life!!! Thank you!
This kind of video set-up is super helpful! Thank you Melissa
Thank you so much. I just found this one when I am very stuck with Lewis structure
thank you so much I went back to the uni after 3 years dropping off and was forgetting all the chemistry I learned back in high school, this helped me a lot. : )
I literally have an exam today and this just saved me. Thank you!!
I got all of it just right. Thanks!
The notes are so pretty I can’t stop looking and by extent I’m actually learning!
Melissa, you put in a lot of sincere efforts in preparation and lucid teaching.. Kudos..
Hello Melissa, this video really helped out. Thank you!
This was a HUGE help for my incoming exam!
Thank you so much!
Love from Italy
Omg I can understand this more easily than my teacher's explanation. Youre a life saver! Haha
Yea
Me too✨✨
These are brilliant thank you so much, you have no idea how much youve helped. and you explain everything so well
I'm so greatful, you helped me with my chemistry exam next week...
This video helped me SO much!!! Thank you, thank you, thank you!
A great tutorial....students usually have problems with octet and expanded octet and fc....but the explanation was great...well done and thank you
Thank you very much, no more questions about this again.
Video was so helpful! Thank you!!!!!!
I just found this video, THANKS! I wish i had a teacher like you, you are awesome!
This is so helpful, TQSM!
It always takes me so much time to get myself to sit down and actually study for chemistry and you always help me in completing my studies. Thank you so much!!
Thanks a lot for the video .This was a great help for my studies.
Using this adding formula instead of the fraction formula is so much easier. Thank you.
THIS VIDEO WAS A LIFE SAVER OH MY GOSH TY
This helped me so much!
Thanks, I have better understanding for formal charges after watching your video.
Have really understood wooow so happy thanks mrs
Everything made sense ma'am you are amazing ❤️❤️❤️❤️
You are THE BEST! Thank you!
this helped a lot...thank you
Thank u sooo much , it helped me a lot !
I'm sure with this, I'm not failing my tests. Thank you so much... I can't believe I fully understand what has been giving me headache, I'm so teary right now
Thank you so much✨✨
I understand much more💕💕
You are really amazing 🎈 my way to chemistry has been made easy by you....God bless you ❤️❤️❤️I love you
Thank you soooooooo much!!!!!
GOD BLESS YOU OMG I'm taking summer gen chem at my community college rn and its been so stressful the professor barely has time to cover everything so she had to rush through this unit and I was honestly trying not to cry on the way home 😭 watching this video definitely cleared up a few things for me and I'm feeling a lot more confident, my exam on this is in 2 days
i think i need a little more practice and ill be where I need to be to get that A !!!
It's very helpful 😍 it would be great if you could give more practice problems, thank you so much!!
so freaking helpful, thank you!!!💛
SUCH a GREAT help Thanks
you are amazing thank you for saving me from my college complicated assignments.
SO HELPFUL.
Thank you... I have just finished my quiz successfully. Since now, I am your new subscriber.
Never would've thought watching this kind of tutoring videos would help me understand something better!! that's it, gonna go for "with us" rather than "with me" from now on
You're the best!!! You literally NEVER fail me :)!
I am from phillipines and an I.E student from pup, thank you for having a detailed discussion about this topic especially now a days, we're just finding our own way to learn by ourselves and tbh, it is really hard.
Extremely useful video for my students. Make more on other topics also !
You are a great teacher 🤗
Thank you! have my finals tomorrow.
That's amazing thank you so much
You are AWESOME! Having a student sitting in was super helpful, too! College life saver
Really you are so good your explanation is very very good and when you was teach I just kept looking at you honestly you are so good teacher and my guide
i do not know how you don’t have more views, you are fantastic!
Thank you so much
so helpful!
You always help me
thank you!
thanku mam it helps a lot
U are truly a savior 💯💯 I love u❤️🥰
I really get to understand chemistry watching your videos
You like 💯 Amazing
Thank you for your content! It has been very helpful!
I actually am confused about the very last problem. Why wouldn't nitrogen and oxygen have a double bond and then fill in the lone pair for oxygen? When do you use double bonds versus lone pairs?
YOU ARE A STAR !
Melissa is the best teacher I have ever met. Thank you so much for making the effort to change our lives!!
This shit is the best, rarely you see vids that tutor, keep going you goats, also nice editing, love how much work you put in!
احسن من شرح دكتورنا
Thank you so much mam
I have a chem quiz tomorrow on Lewis Dot Structure and I was super worried about it, but now I'm not worried at all. Also, I never comment on youtube videos but you are such a great teacher that I had to say thank you!
gracias!!
Really helpful 🙏🏼♥️
I really like these kind of problem solving videos
Thank you so much Maribel !!! please keep posting more for OChem. I am learning more with you than with professor.
It would nice to have an OCHEM basis video.
Their is a trick I got from this whole lesson
That is ,that when their is just a single minus sign that means I will have just one single bond in the structure and that also implies to the sign of minus 2
Thanks for this great video
it was good..
i was like genuinely clueless about lewis structures but now i have such a clear understanding of them that's crazy
HIIII Melissa, I just wanted to ask if it matters where we put the hydrogen for the oxygen in the last problem?
You are the best ❤❤❤❤❤❤
Melissa the wise giver❣️❣️🕊️🕊️📝
Your formal charge equation I prefer over the book! Thank you so much I understood it better practicing with you.
Melissa, I grew up in a cult where we weren't allowed to learn Science at all. I recently started college and was terrified of how I'd do. Over the summer I watched all of your videos to prepare and I just took my first Chemistry test ever and got a 95%. Thank you!!!!
wow
you're awesome!!!!!!!
Please upload a video on acids and bases,my favorite teacher
I cannot thank you enough!!!!😭😭😭😭😭
Love u Melissa ❤️
why is it more favourable to have a neutral formal charge on the central atom? do you have a video about this?
Thank you melissa it was really helpful!!❤ i could nt understand one part at 24:48 why one of the Fluorine atoms have only two lone pairs i understand why the other Fs have 3 lone pairs but i don t get why this F has 2 lone pairs
Thanks from India mam
You’re the best
Can you make a video about functional groups? PLEASE AND THANK YOU!!!
Awesome!
Thanks!
What do you do if, in order to make the central atom have a formal charge of zero, you can't meet the octet rule? Which is more important if you can't do both? For example- CCl2. To make carbon have a FC of zero, carbon will be left with only 6 valence electrons and carbon is not an exception to the octet rule.
Thank you for this video. However, I just had a quick question I thought that the central atom always has to have a charge of zero. Because for No3- the charge on the nitrogen is 1 and thats the right structure. So how would you know if the central atom is supposed to be zero or have a charge on it? Thank you in advance
