HW#18a -- Thursday, Feb. 9th

A polite reminder -- many students have not yet turned in the bottom of their Syllabus Update (golden sheet), signed by a parent or guardian. This is one of the first grades of the second semester, and an easy one at that. Don't delay in getting it done.

A second polite reminder -- since we missed binder checks the other day, I will instead do it on Friday (tomorrow), before the test. The days I will most likely check are Jan. 31 (with the Chembalancer practice on the back side) and Feb. 1 (with the Lantern Lab report as the practice).

And now, on to the HW assignment:

HW for today -- finish "Balancing Equations" practice WS

The HW for tonight will be to complete a piece of practice that you should keep in your notebook. This worksheet was handed out today, and was called "Balancing Equations." It has a FRONT and BACK side, with a total of six problems. For each problem, you need to complete the final count on the atoms table AND write the correct coefficients into the equations. For example, #2 should have all of this information filled in:

Tuesday, Jan. 31

No online HW assignment today; instead, make sure that you finished the 'Chembalancer' worksheet that we've worked on for the past two days in class. If you need to go back to the Chembalancer program so that you can finish the problems, you can click [HERE]
Don't forget that #12 and #13, which you need to draw out yourself, are also part of the worksheet.

HW#17a -- Monday, Jan. 30th
