Things you should know about not mentioned in the video: Know that transition metals require a number for instance CuSO4 would be copper 2 sulfate. Make sure you know what a pure compound is and a pure substance. Also make sure to know what dipoles are and if you have say 10g of C2H4 make sure you can figure out how many moles or grams you have of say carbon or hydrogen. Don't forget about sig figs and how to name acids. ate - ick, ite - ous. Make sure to remember how to identify aqueous solutions and solid solutions. There's videos to remember such as NAG SAG. There's also acronyms to remember strong acids and know that all strong bases have OH in their formula.

[@anangelsdiaries]

For those wondering at 8, why he simply added 1 and 2 to them. It's because the concentration we are looking for is actually the concentration of H+ ions in the solution, but since there are two moles of H in the molecule we have to add that 2, on the other side since it's a base we have the OH- concentration, however since there is only on mole of OH, the coefficient in front of the m1v1 is well 1. Hope it makes sense, and that I am not mistaken hahaha.

im taking my chem final tomorrow and i currently have a 42% in the class. Ya'll wish me luck. and hopefully ill remember this so i cancome back and update yall

[@SavannahPhillips04]

what’s up u guys, if ur taking this in 2020, and you have the grey version, just know there’s a lot of math. i got a lot of A’s and B’s but i also guessed quite a bit. i made a 68 which is passing in my class, so i made a D. i also have failed every exam so far in there. so making a 68 was like making a 100 for me lol

[@whales0310]

looks like me and you are in the same situation

[@SavannahPhillips04]

whales03 i mean if you can do better than a 42 on an exam then you should make like an 80 on this, so like best of luck to you, and don’t use C as your guessing letter. there are very few of them. stick to A’s and B’s

Thank you for your video. I'm taking Chem 2 this semester and forgot everything from Chem 1 that I took 6 years ago. This has been extremely helpful!

[@Lemmer2005]

As an engineering student, ive always prefered the later 3 parts of STEM, and had a weak point in science. Being put in a Chem181 course really shook me up. Yet, with your videos such as this one, its been significantly easier to learn what I need to. Plus in HS with calc 1 and 2, you've been a lifesaver.

Many professors employed in universities today can't compare to you, because of your deep understanding of how learning really works. Your efforts save countless students all over the globe. You are appreciated! God bless will you indeed, He'll be the one to return the favor to you. Thanks!

i should’ve watched this at the beginning of the semester

[@ProtectandProsperGroup]

First of all I wish I would've watched this as a sophomore in high school struggling in AP Chem and eventually a 2 on the exam smh but now I'm a college freshman and my final is tomorrow so I'm just watching this on fast forward and working through the problems with the video. Thank you so much for this video because my final is a multiple choice exam but EVERY other exam has been free response solving so I had no idea what questions were going to look like. This is perfect, god bless you guys!

s vandermeer I got a 65 on the exam and a 78 as my final grade. So a C. My professor was terrible but was switched mid semester. It was a hard game of catching up. But this did help me a ton.

[@svandermeer6551]

Mikal1209 Im going through almost exactly that right now. Im just hoping to get a B, and i totally would have one right now if my teacher was more dedicated to helping her students :/ At least it was a high C in the end!

People studying for the ACS, I highly recommend watching all his videos related to the ACS review at least one time. I took it and was able to do a little above average from just a couple days of studying from his videos. Hardest part is the time, I recommend doing problems over and over again until it is extremely easy to do in under a minute. Good luck :)
