Re: Isopropyl vs Propyl [ENDORSED]

Isopropyl has the specific orientation of being attached to a central carbon atom with two CH 3 molecules attached (so in IUPAC naming it can become dimethylethyl), whereas propyl is three carbons all attached in a line branching off the main carbon chain, so it's two CH 2 molecules and one CH 3 mol...

Re: Has the formula sheet changed?

That's a combination of two equations equal to ΔG. ΔG=-RTlnK and ΔG=-nFE. They're rearranged and set equal to each other in that problem

Re: Oxidation Numbers

Some other good things to know about oxidation numbers is that O is almost always a -2 charge when it's with other elements in a compound like SeO 4 2- . For this one the O charges will add up to -8, so the Se must have an oxidation number of +6 to make the overall charge -2. Also, elements in their...
