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.

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.

number 9 at 42:23 I realized that by using PV=nRT, you can still solve the equation by first finding n. On top of that, PV=nRT is actually provided on the formula sheet.

Took the ACS this morning. This video really helped! If you can do everything in this video, you can do everything on the test. Good luck!

[@bobbuilder2583]

really? what subjects did it focus on?

[@tessstalter7256]

Do you need to know the labchem section? It was in the study guide

[@allisonspurlock5745]

Bob Builder It was really well organized. Questions about certain subjects appeared in blocks. So for example, the first 7-8 questions of my exam was basic skills questions, like how many protons does this atom have, naming compounds, etc. Then dimensional analysis, there was a thermochemistry portion, gas laws, Lewis structures, hybridizations, electron domain geometries. Those were the sections that stuck out to me the most. It wasn’t half as bad as I thought it was going to be.

[@allisonspurlock5745]

Clemence Declaire I didn’t use the study guide, do you mean experimental yield, percent yield, things like that? If so, yes. I had a random experimental yield question in the middle of my test, but yours will likely be different. I’d review those concepts, just to be safe. :)
