其中P为pressure(单位:atm), V为volume(单位:m3),n为这个气体的量(单位:mol),R为常数(AP一般会在最前面的equations and constants sheet提供几个,其中8.314 J/mol·K,0.08206atm/mol·K这两个比较常用,大家根据自己已有的信息选择需要用哪一个),T为温度(单位:K)。我们可能还会碰到同一个sample里有几种不同...
The AP Chemistry reference sheet is actuallythree pages of information.It will be at the beginning of both the multiple-choice and free-response sections of the test, so you'll have access to it for the entire AP Chemistry exam. This means you don't need to memorize any of the informatio...
“You have no idea how your PDF files have helped me in learning chemistry. I've repeated Chemistry FIVE times and am still struggling with the materials. Not until this term, have I finally understood it WELL with the help of your notes. The notes are so wonderful and very well explaine...
For Chemistry, you will use only the circles marked A–D. You must complete the answer sheet using a No. 2 pencil only. Mark all of your responses beginning on page 2 of your answer sheet, one response per question. Completely ill in the circles. If you need to erase, do so ...
