Help me understand oxidation numbers

So I have a chemistry test this week and ive been studying but still don't really understand the whole oxidation numbers things, and no this isnt a homework question or anything I just was wondering if someone could clear it up

to figure out if a reaction is a oxidation reduction reaction or not, I know oxidation means the molecule loses electrons and reduction means they gain but i dont understand the whole balance thing

Thanks!!

youtube might have some good info, there are professors who make videos, i just saw some on oxidation numbers, hopefully it helps

After balancing the H20 and O2, you need to balance the charges by adding electrons to the equation.

Look over that link....if it is still confusing then I'd advise you attend office hours, a study group, or locate a tutor. (actually, you still may want to do one or a combination of those, anyway). It may be a little easier to have someone walk you through balancing the reactions in person if you're still lost after reading the text. Once it clicks, you'll be fine--I actually enjoyed this part of P.Chem 🙂 Just practice several problems and you'll find that it's really not so difficult once you get the hang of it.

It's all about periodic trends. There's some of that in your gen chem book or inorganic chem. Seriously, for all the students I've tutored...teaching them periodic trends has been the 'toolbox' for them really to destroy some hard-to-understand concepts.

SDN is not to be used as homework help. Hope your test went well, though!
