HW#19b -- Friday, Feb. 17th

Complete these six problems by determining which type of reaction each is. On notebook paper, write out each reaction first. Remember that each reaction MUST be one of the five types -- combustion, synthesis, decomposition, single replacement, or double replacement.

If you want extra credit (bringing your graded HW up to a check double plus), then after saying what type the reaction is, go on and balance the equation (determine what the coefficients should be).



PS -- Yes, these are the last six problems from the reaction types worksheet that was handed out in class. This puts you that much closer to finishing that other assignment!

No online HW today -- just finish WS from class

On Thursday, you started work on a 'reaction types' worksheet in class. There is 22 problems, and you need to be able to say which type of reaction each one is. When you've finished this practice, put it back in your notebook with your Feb. 16 'DO NOW' -- and know that I will very likely be checking this day as part of the notebook check next week.

HW#19a -- Tuesday, Feb. 14th

See the assignment in the image below. Don't forget, it can only be one of the five types we discussed in class: combustion, synthesis, decomposition, single replacement, or double replacement. Also, remember how 'displacement' can be said in place of 'replacement' (either is acceptable).

BONUS: See if you can recognize which one is the special 'acid-base' variety of double replacement...

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:

HW#17b -- Wednesday, Feb. 1

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.
