So I've been having trouble in chemistry and it's only getting worse, probably due to the fact that I don't study much.

I was wondering if anyone knew some goods sites that could help? My trouble is just about everything up to oxidation-reduction :(

[SoulPlaya]

There's really no shortcuts. Just study more. Try Khan Academy on youtube for supplemental help if they cover the topics you need help in.

Study.

/thread.

[salva]

Ochem?

definitely a good place to start. Otherwise, I would suggest simply looking the term/theory up on Google for further reading.

When it comes to chemistry, you have to study hard or cheat hard. There's not very much of an in-between option.

[Kentpaul]

Drop the class and find something your better at.

[FelixOrion]

Study. Study some more. Think you're done studying? Then keep studying.

If you don't get this now, future chemistry classes are gonna blow because nearly everything you learn now gets built upon later.

yup

chemistry is one of those subjects that I would always get near 100% on... but the line between getting 100% and failing for me was very small. by that I mean the amount of studying necessary to actually understand the material would ensure an amazing mark, but any less than that and I wouldn't have scraped by with a 60 or 70%. I would've completely bombed. you can't BS your way through chem, physics, or math classes. buckle down, boy. the good news is, your hard work will likely be rewarded, especially if you're taking 1st or 2nd year chem classes. people dumber than you have gotten 95%+ in this classes, trust me.

you'll also need to be more specific if you want help.

I'm up for hire. My fee is 20 euro/hour.

Uh, that's your problem. Try studying and then see if your struggles still exist.

[ssolitare]

Just like with all foreign languages, you have to practice and study to familiarize yourself and make it stick.

Practice is the key, doing it will make you understand chemistry clearly. That's all you need to do.

[nick nacc]

I am in the same boat. It's never too late to buckle down an study your ass off. Never too late man.

[The Last Wizard]

Well I'm looking for some supplemental stuff. Things thall help to reinforce the basics, I'll check khan academy.

[Backwards Marathon]

If you don't read the textbook (like 80% of people in gen chem classes) then that's the best place to start. Then work the problems at the end of each section/chapter.

As far as supplements go most universities have some short of free tutoring, Kaplan review books are short yet precise, and as mentioned above Khan is pretty good too for video.

[Bombadil]

Don't mix bleach with ammonia. That's all I've got to say, son.

[Backwards Marathon]

Ochem?

Loved orgo until Aldols, Claisens, Michaels, etc. Maybe after my exam tomorrow I will start loving it again though.

[abusori]

Potassium + water, however, must be experienced at least once. Preferably while wearing safety apparel just in case.

[Lyude77]

I would just do a lot of the problems in the book. That's all I had to do for basic Chemistry. At least go over the basic examples and probably look over the definitions again. You should know/remember what material is important to look over since you were already tested over it. If you do enough homework, you may not have to study by reading (unless it's Organic or something that needs more memorization).

my teacher does this with a youtube vid.

After almost injuring himself during a live demonstration, school forced him to stop doing it :(

[Dany M]

That sucks that your having trouble with the class.

Do they provide a book for the class?

[maomaoIYP]

Seek help from GAF? I think I remember seeing a homework thread? As well as a science-GAF thread?

[abusori]

Our teacher grabbed a tub of water, said "You might prefer to move back a bit," and then dropped a big chunk of potassium without skipping a beat. It was hilarious, but I was not on that side of the room. XD

This is the same teacher that informed us his exhaust mechanism for gases was illegal but he didn't give a shit, so you might imagine.

[Hoo-doo]

Just study, son.

You got books, right? Make time to really sit down and work through it. If you can't follow, go back another chapter and start there.
Make sure you don't just answer the questions, but try to think why these things are the way they are. You have to want to know.

I got a 9 on my Chemistry entrance exams, to try and get into med school, without having followed a single class in around 6 years. Just studying by myself. All it takes is a bit of discipline.

[yogloo]

Be cocky and funny.

I actually have a question on Electrochem and didn't want to make a thread about it so just assuming I can bump this one.

Here's the question:


First of all, I wanna calculate the electric potential in standard conditions. isn't it the Zinc that's getting oxidized and the H2O is getting reduced? The reduction potential values are .763 for Zn and -.8277 for H2O, yet the answer is .3923V

I think I'm having trouble with what's getting oxidized and what's getting reduced.

This is beyond any chemistry I've taken, and it's been a few years, but I think you are right just by glancing at the oxidation states. Zn is being oxidized from 0 to 2+ and H is being reduced from 1 to 0.

So I have a random question brought up from someone and I couldn't answer it and felt like a dumbass, and I can't start a thread so I figure I'll ask here. Hopefully someone sees it.

Say you have concentrated hydrochloric acid at about 12M and you want to make 10mL of a solution that has approximately 2mg chloride ions in it. Anyone know? For some reason the way to solve it escaped me.

[Alebrije]

There are this guys , maybe they can help you :

I got 5.0 x 10^-6 L which gives you 5.5x10^-5 moles which converts to .002g HCl. Put that L into 10mL of water and you'd have .002g Cl- floating around since it would disassociate I think. Probably totally off though.

Huh. Converting that to grams is about 0.0059g of 12M HCl per 0.002g Cl- ions, which is what I thought I would need...but this person claims it's 0.00268g and won't tell me why.

That is all.
