Couple of Things for AP and the Electrolyzer
The date to learn how to build and install an electrolyzer has been postponed until next Friday at noon. Today, only Bridget showed up, so we decided to wait until next week. Let’s all try to be there OK?
The book seems to be an issue right now. I did not realize that they were not going to be selling the books until mid August. Anyway, here is a plan around this…
A few of you have purchased books online and so you have been working on the assignment. That’s good. I have a few books to loan out to those of you who want to get started ASAP. What I would like to do is loan out a few of these books with the intention that you all will work on the assignments together and share the books. The reading for the first few chapters is not difficult and you should be able to catch up fairly quickly.
IMPORTANT: The schedule for the return date of school is unchanged. The day we get back we will have a quest on chapter 1 stuff.
It will cover…
chemical symbols and names, definitions of atoms, elements, molecules and compounds; physical properties; density and the density equation; temperature scales and conversions (C and K); extensive and intensive properties; chemical and physical changes; characteristics and differences of the 3 states of matter; the kinetic-molecular theory; differences and similarities between pure substances, homogeneous and heterogeneous mixtures; metric prefixes and conversions; dimensional analysis and factor label method; difference between accuracy and precision; significant figures.
This should cover chapter 1. If you do not have and cannot get to a book, explore the internet (especially my favorite sites) and read up on this stuff.
The stuff to know for chapter 2 is:
the history of the atom; the structure of the atom (p, n and e-); isotopes and relation between p and n; RAM; molar mass; use molar mass in calculations; know groups names, periods, metals, non-metals on periodic table.
The stuff for chapter 3 is:
name compounds; write formulas for compounds (ionic and molecular); oxidation numbers, what they mean and what types of atoms give or recieve e-; know polyatomic ions (symbols and names); calculate molar mass; calculate moles from molar mass and vice versa; percent composition; empirical formulas; find the number of water molecules in a hydrated compound.
Most of this stuff can be found in last year’s notes also.
Be sure to ask lots of questions on the blog so that you do not have any when we get back. Check and re-check the schedule that I gave to you last year before you left for the summer.
