CHEM: Day 95 - Homework
For tomorrow, Periods 4 and 8 have no homework due. (Except for you careless readers in 8 - *sigh*)
Period 1: See yesterday's post for your homework.
Period 3: 1) Read pp 870-874
2) ?s - Radioactivity Worksheet I + p 894: 40, 41, 46, 48, 51
That should do it.

CHEM: Day 94 - Homework
Well, this pretty much fell off the radar for the month of January. I failed.
Time to make this useful again.
Homework due for Tuesday, Periods 3, 4, and 8/Wednesday, Period 1:
1) Read pp 860 - 869
2) ?s - p 894: 35 - 37, 42, 45
For lab: Period 1 - Read the following links, in order:
Nuclear fission - Read the Introduction, Section 1.5 (chain reaction), and History sections
Nuclear fusion - Read the Introduction and the Overview
Nuclear weapons - Read the whole page. If you like, you can click through the links on the right of the page.
NB: You will not understand everything on these pages, especially if you read outside the indicated sections. You won't understand every term in the sections either, but you will be able to understand most of them. You will gain sufficient background from the reading for tomorrow's exercise.
(Example: Most energies on these pages are given in a unit we don't use in first-year chemistry, the electron-Volt or eV, because this is the standard unit for talking about the energies involved in the nucleus and the motion of subatomic particles. 1 eV = 1.60 x 10^(-19) J. You don't need to know the value of an eV in order to understand the article, but it will probably bother you a little. Just read over it.)
That should do it.
