Im starting summer intensive classes for chemistry in 3 weeks. What are some good resources online or book form, or good things to know/memorize/learn ahead of time.

You could go online immediately and start learning about basic chemical reactions and balancing equations. Oh, and grab a Schaums guide to Chemistry and start practicing alot of stochiometry questions. You will see alot of those in a beginning chemistry course.

Balancing equations and learning rules for reactions is something you'll have to do over and over again. That'd be a good place to start too. Good call on stoichiometry. Gas law stuff is easy, but you may want to practice it if you get mixed up with long arithmetic problems. Is it chem for science majors or chem for everyone else?

Oh, memorize the common polyatomic ions. Here's a list

Definitely the polyatomic ions... they take some time to memorize. Also, you might want to get comfortable with unit conversions. I remember that being a real pain in the ass when I first started chemistry. You will end up converting units in almost any college level science course, so it is a really good thing to practice until it becomes second nature.

It's not bad if you learn how to do a decent unit analysis equation. In chemistry, don't be afraid to make super-long equations; In gas law problems they can easily be the width of a page and change. It helps me to expand power units to make sure I don't forget anything, for example- (1cm)(1cm)(1cm) instead of 1cm^3. Doing the equations well is a great way to check your work. If you're trying to get a density answer, for example, and your units don't reduce to mass/volume, you did something wrong.

I'm taking Intro Chemistry in the Fall. Oxidation numbers and polyatomic ions are very important for this class?

What's the catalog description? Probably yes, but of varying detail depending on the intent of the class.

This course is a preparatory course for students who have never had chemistry and covers the metric system, atoms and elements, bonding, solids, liquids, gases, stoichiometry, solutions, reactivity, and acids and bases. The lab includes experiments in organic chemistry. This course is appropriate for nursing students as well as students who will pursue higher level chemistry.

 

 What is the best stuff to learn for that ?

Everything listed above. The difference between the intro chem class and general chem (first couple classes for science majors, say) is just in the amount of detail you'll need to learn.

I dunno why they don't teach dimensional analysis earlier... apart from the name is really simple and foolproof. I taught an elementary school kid how to do it in about 5 minutes, and she was perfect with it.

While this technique is very powerful, it can come back and bite you in the ass, as you can often get to the right answer without actually UNDERSTANDING how you got there.

Agreed, also true with many other mathematical techniques. Figuring out the real life meaning of things like integrals and diff e q's is a triumphant (and necessary) moment for understanding science, imo.

Also, with regard to Chem... www.chemistry24.com The one and only reason why I had the highest average in the class in gen chem and beat everyone on 3 out of 4 exams and did 95 on the final. Next highest score was 89, class average of 68. C24, all the way. I'm hoping the orgo is half as good. Also, "The Teaching Company" has a chemistry DVD set out with a high school teacher who was science teacher of the year in the mid 1990s. He made a big point that you should avoid dimensional analysis until you REALLY understand the material first. D/A or Unit Factor (they are the same thing) allow you to solve for units without understanding.

A particle is also a wave. Have fun with that one.
