Chemistry 11:  At the start I collected signed outlines and showed everyone an answer key to the States of Matter and KMT WS.   We took notes on "Chemistry", read 3.1 and 3.2, and completed Unit III #s 1-3, 5, 13-15, 22, 24.  Answers are at the back, and this assignment is due Friday.  We discussed how being on time, bring the right supplies, completing all coursework, and treating everyone well are important for maximizing your performance and for making Chemistry at least partly enjoyable.
We observed a number of examples of matter, some were mixtures and some were pure.

Chemistry 12:  The WS titled Rates of Reaction is due Thursday.  Answers below in blue.

1)  .0370 mol Cu
2)  0.000 27 g Mg per s
3)a.  0.014 g Cu/s;   b)  0.000 22 mol Cu/s
4)a.  .0071 g Zn/s;  b)  A higher concentration causes a faster reaction rate;  c)  28 s
5)  .428 mL CO2/s
6) a)  slope decreases, so rate decreases over time;  b)  Oxygen from the air is reacting with Fe and forming a solid product.  The additional mass is due to oxygen atoms;  c)  0.520 g O2/day;  d)  answers will vary on this... my tangent had a slope of 0.44 gO2 per day.
7)  0.144 mol HNO3

Chemistry 11: WS titled Kinetic Molecular Theory and the States of Matter, due Thursday.  Read section 1.1 and make the map as directed.   Graph paper and the rest of your supplies will be checked on Friday.
