Was that always a rule in the past?quizbowl13 wrote:according to the ever sacred rules, it just seems that you must be proficient in Aqueous solutions and Redox. each accounts for 50% of the score.
also, students MUST wear long sleeve shirts
Maybe for general chemistry, but I don't think it's necessary for the main two topics.2win wrote:Oh, do we have to know about autoionization too??

Re: Chem Lab C
Two questions: 1. What would the actual lab portion of this event be like? What are the different things we might have to do? 2. From your prior experience at various competitions, is an AP level understanding of most of the subjects that may be covered adequate?

Re: Chem Lab C
I have a question about oxidation numbers. I know that they're assigned to different chemicals and ions and such, but how can you ever remember them? I tried to memorize them and I simply couldn't. Does anyone have a mnemonic device or something similar?
ALSO: Half-reactions. I don't understand them. Please help?

Re: Chem Lab C
You don't have to remember all of them, mainly just oxygen's and hydrogen's. There's formula to figure them out... the only things you have to memorize are the rules (aka exceptions to the formula)...

Re: Chem Lab C
I've been out of Science Olympiad for a long time, but I would recommend pulling a book from the library (might have to use inter-library loan) called Quantitative Chemical Analysis by Harris, or a similarly leveled analytical chem book if you want to be really super in this event and to try to get into some of the subtleties.
Then again, back in the day, the topic was nuclear chemistry and just from reading the AP Chem text I had and the AP review book (probably not the best prep in hindsight), my partner and I were probably a calculator error away from medaling at NYS states.

Re: Chem Lab C
It also helps to use USNCO tests. The theoretical portions for these tend to be around an order of magnitude harder than the regional/state tests.Wongman wrote:I've been out of Science Olympiad for a long time, but I would recommend pulling a book from the library (might have to use inter-library loan) called Quantitative Chemical Analysis by Harris, or a similarly leveled analytical chem book if you want to be really super in this event and to try to get into some of the subtleties.

You can say that again, that thing was quite the doozey. Harder then the Nats test I would saybinary010101 wrote:It also helps to use USNCO tests.

Re: Chem Lab C
Does anyone know what kind of Chemistry book would talk about Beer's Law? I have looked in 2 college level general chemistry books and neither mentions it.
When it comes to the future, there are three kinds of people: those who let it happen, those who make it happen, and those who wonder what happened.
