🙌 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!

It’s crazy. Every time I scroll through new uploaded videos in my subscriptions tab, I see another one of your videos. They’re always about what I’m currently learning in my chemistry class. Crazy. I will certainly utilize your videos when needed. 🔥😂

[@legacybluey]

these videos are exactly what i needed! thank you so much

[@isabellebaginski3061]

omg im learning this rn online and it was so confusing but ur video rly helped ty!!

[@i0am0bananahannah]

So helpful! I replayed the first couple of minutes like 4x..lol..but it finally clicked! Thank you!

[@danicalopez5265]

I liked all of your videos! It helped me so much in my Chemistry class.

[@youseeIkick]

Thanks for showing what happens to a ion with a +3! I've been killing myself over trying to find out why it only moved the answer over 1 element instead of 3.

[@martinsimbeye9119]

Melissa taught us the best method for electron configuration

[@donnam4730]

Thank you, this saved me

[@melissamaribel]

You’re very welcome 😊

[@edenparzygnat1085]

U saved my life and my chem Mark ❤️❤️❤️❤️❤️

thanks for u 😍❤

[@Ayaksingh]

Hey👍 It's good, from India🇮🇳

[@JustinGarfield1]

Thank you!!$!

[@masudjoshy2175]

Thanks

[@jennifercarmona9788]

soooo freaking happy I came across your videos! I am currently taking college chem for the first time and i am determined to earn an A

[@juicyjny]

Did u end up earning an A? I am in the exact same situation right now...I'm an english major on top of that hahaha.

[@rutho.6282]

Thank uuu

[@shaunayy8700]

Are all the elements in the d-block follow the rule where the d sub shell fills first before going to the s sub-shell as you showed on the “exceptions” slides or is that only for 3D series?

[@Paytoon42]

This is my salvation

KZbin IS MY FIRST LOVE ❤ 😍 💖 ❣ I LOVE YOU KZbin 😍 ❤

[@fatinfarhana2634]

11:22 the highest end value, in that case, is from 4p. If there is only until 3d, will be there no highest end value?

[@juicyjny]

Ugh having a woman teacher is so refreshing! I've only had male chem teachers and tutors up until this point and I constantly felt stupid and patronized. Melissa, I admire the poise and patience with which you answer questions, especially since most of the questions are ones I had myself! Best chem explainer I have encountered yet :)

Explain how to write diagram of orbital notation method

[@melissamaribel]

Since you asked so nicely, here's the video: kzbin.info/www/bejne/j2mcpGtvoKqmgLs

[@DanLe-vl8zt]

For Fe3+, can you please explain why it is minus 1 instead of 3. Thank you

[@slvmogollon]

She had already removed 2 from Fe2+. She was just working from Fe2+ to Fe3+. If she was showing Fe3+ from just Fe it would have been minus 3. So you’re on the right track I can see where it’s a little confusing

[@xgamerxplays6478]

do you have any videos on intermolecular forces?

[@melissamaribel]

Yes, here it is kzbin.info/www/bejne/l4C9hKJuor53mNk

[@xgamerxplays6478]

Thank you very much! I got 90% on my quiz :D

[@laceysky3605]

what about Xe 4+

[@user-sz7mq5hx9f]

hi for chromium in the video its stated as (Ar) 4s1 3d5 how ever im really confused why fir my lectures the teacher always write it as (Ar) 3d5 4s1 The d is not supposed to come first right? ( based on the aufbau diagram i always use) ive been stuck on this for day plss help thank u!

[@ajtrott1]

I think both forms are accepted. It just looks neater I think to write 3d before 4s (even though 3d is higher in energy than 4s). Its a moot point but hope that makes sense!

[@structuralengineering4dummies]

bless you Melissa, saving my ass since sophomore year of high school istg

[@augmentumstratus8434]

No but ehy eould it not remove an elecyron thats higher in energy? Why eould it remove an electron that is lower in energy(more stable) ?

[@rebelkaran6133]

Configuration of Au ???

[@larissatorres7407]

taught me better than my professor teaching this for an hour AHAHA

[@channel-ts4fd]

You are beautiful I love ❤ you ❤ ♥ 💖
