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.
