Thurs-Day 1
AP Chem - continued to discuss the basis of the "ideally behaving" gas laws in terms of 1) kinetic energy/force of collisions of the gas molecules and 2) frequency of these molecular collisions (the more collisions per second, the greater the net force transmitted per unit area i.e. the greater the gas's pressure).
We then did a solution and gas stoichiometry problem.
We manipulated the ideal gas law into four different forms, one of which is most easily used for a given type of problem depending on whether mass, GFM, or density is given at a given T,P, and V.
We discussed ways of measuring whether a given sample of gas is indeed behaving ideally or not, and the degree to which the sample is exhibiting ideal behavior (PV/nRT ratio = 1).
The following Chapter 4 Brown-LeMay text questions are worth one bonus point each given that the submitted answer meets EACH of the following requirements:
1. legibility and clarity of writing!
2. detail with respect to units, cancellation, formulas; each step is explicitly shown.
3. accuracy (and precision/sig figs in final answer) of course.
4. description of the problem solving process via formulas, words, logic/reason.
Answers that meet the above requirements sufficiently may be rewarded one point each; an answer of inferior quality that is submitted before an answer (to the same question) of better quality will result in the point being awarded to the higher quality answer (as judged by the above criteria); in other words, you don't have to rush to submit your answer first.
The questions: (one point for answering all of 68,72,74,78 - these are simple questions, so several need to be done to earn the point) ,(100 and 103 for one point), 90, 104, 107, 109, 110, 113, 114.
There are also two non-text bonus questions posted in a file in the Unit 4 folder on Edline.
Looking forward to seeing your top-quality responses, which will then be posted on Edline. You may use your initials at the end of your answer, if you want all-time fame :)
Bio - discussed the levels of cellular organization in complex organizations; these various levels are required to carry out all of the life processes in complex organisms because these organisms have so many different chemical environments within and around each organism, so there must be whole systems of organs that can interact and aid each other in these different biochemical environments e.g. there is no atmospheric oxygen surround the bone marrow cells inside your body, so you need circulatory and respiratory organ systems to get the oxygen to these cells for aerobic respiration so that these cells can make ATP for energy for survival.
We also went through two important examples of how organelles work together to maintain cellular homeostasis.
In 10/11, we started our plant/animal cell labs.
