LARN 168 C42D4
Study for the summative assessment on chapter 20 test on Oxidation-Reduction Reactions that is to be given on your next school day that our class meets. Today is day 168. Study for your test which is scheduled for school day 169! If your class does not meet on day 169, today's home learning activities are listed under day 169 and on day 169 your home learning activities are those listed below.
Start the following in class:
1. Go to http://www.phschool.com/webcodes10/index.cfm?wcprefix=cda&wcsuffix=1200&area=view and take an online formative test for chapter 20, Oxidation-Reduction Reactions. Then click on the Score My Test button and study anything that you do not yet understand.
2.a. Review and study your notes, and your journal reflections. Study your learning log, your Cornell Notes, and anything that was misunderstood on the Chapter 20 Study Guides, Chapter 20 Section Reviews, Chapter 20 Oxidation-Reduction Reactions [Formative] Test A, and other work sheets which you now have checked using green ink. Look up anything...
LARN 167 C42D3
Start the following in class:
1. For your journal today, J167A, you are to show how to use oxidation numbers and the single atom ratio method to balance four chemical expressions. In your journal notebook, on the first blue line title this assignment Redox Problems. a, b, c, and d. For each of problem,
record the oxidation number for each atom in each species on a short line segment drawn above the elements symbol in each formula given in the initial and final states of the chemical expression.
record the reduction half reaction and the oxidation half reaction for the transfer of equal numbers of electrons.
record the oxidizing agent, the reducing agent, and the atom ratio that could be used to balance the chemical expression.
Then balance the chemical expression. Use the single atom ratio method to balance the following expressions as explained in the following notes:
Correctly copy the formula and phase of each reactant and product in the...
LARN 166 C42D2
Start the following in class:
1. For the first part of today's journal entry, J166A, assign oxidation numbers to each single atom of each chemical species in chemical expressions a and b given below and then show how those oxidation numbers can be used to balance the chemical expressions. A page in your learning packet has space for you to show your work for these two problems, or you can do problems a and b in your journal notebook.
