LARN 102 C26D2
Start the following in class:
1. Do the next equation mole ratio problem assigned on LARN 99.
2. Do the next equation mole ratio problem assigned on LARN 101.
3. In your Journal Notebook write your journal entry on sheets of three holed 8.5 inch by 11 inch ruled paper.
- In the upper right corner white space of each upward facing page, use a blue or black pen to write your hand in number within a circle followed by your name.
- To the left of the red marginal line, print J102A.
- The required focus topics, J102A, for today are:
- How does one calculate percent yield?
- How does one calculate percent discrepancy?
- What is the difference in meanings of the terms percent discrepancy and percent yield? Explain the difference with an example.
4. At the back of your text, find and read pages R4 and R5 about the elements around you in the earth, oceans, and air, and about the elements within your body. For your second journal entry, J102B, record the answers to these questions:
a. What is the most interesting fact you read about? Please make your answer to this question longer than one sentence.
b. What makes this so interesting to you? Please make your answer to this question longer than one sentence.
c. What is one fact about oxygen that you either were not familiar with or were least familiar with? Please make your answer to this question longer than one sentence.
Recommended for those who have time left in their 45 minute study period, but not required of all:
1. Log on to a computer connected to the internet and use a flash enabled browser to go to http://lauratalley.edu.glogster.com/chemistry-114/ and examine all portions of this poster on the percent yield of a chemical reaction. If your browser is set to allow flash video, you can view the video. If not, that is O.K. Take Cornell notes concerning things that you understand differently as a result of studying the poster, and record any questions you may want to raise when you get to class.
