Start the following in class:

1.  Download the flipchart on chemical quantities after clicking on the following link: Chemical Quantities_v6.

The required focus topics for today, J80, is

A mole is a measure of the amount of substance that contains the same number of items as there are carbon atoms in exactly 12 x 10-3 kilograms of carbon-12.

a. How does one find the mass of a mole of any given compound? Show your labeled work in the way demonstrated on pages 40 and 43 of the Chemical Quantities_v6 ActivInspire flipchart.

b. What is the mass of a mole of silicon carbide, SiC?  Show your labeled work in the way demonstrated on pages 40 and 43 of the Chemical Quantities_v6 ActivInspire flipchart.

c. What is the mass of a mole of water, H2O?  Show your labeled work in the way demonstrated on pages 40 and 43 of the Chemical Quantities_v6 ActivInspire flipchart.

d. What is the mass of a mole of phosphorus trichloride, PCl3? Show your labeled work in the way demonstrated on pages 40 and 43 of the Chemical Quantities_v6 ActivInspire flipchart.

e. What is the mass of a mole of sodium chloride, NaCl?  Show your labeled work in the way demonstrated on pages 40 and 43 of the Chemical Quantities_v6 ActivInspire flipchart.

2.a.  Use the PQ5R or SQ5R method to prepare study guide for text section 10.2 on Mole – Mass and Mole – Volume Relationships or go to https://socratic.org/chemistry to research the topics brought up in section 10.2 of your text.   Read section 10.2 in your chemistry text, pages 297 through 304, and as you do, create a study guide using the SQ5R or PQ5R method explained in class and on the distributed handout packet. You may record vocabulary entries in the body of your study guide, or you may check them off on the chapter 10 vocabulary list as you think about the meanings of the terms and add any notations to the vocabulary list for clarifications sake.

2b. Writing in blue or black ink, place your hand in number in a circle followed by your name in the upper right white space of a piece of three holed composition paper in your learning log that hasn’t been written on. Place the page reference for the problems to be considered to the left of the red marginal line on the first blue line. Centered on the first blue line, write a descriptive title for the learning activity such as Section [chapter #.section#] Responses. Before you write your response to each question or problem listed below, write its designation to the left of the red marginal line as listed below, followed by your response in ink to the right of the marginal line.

  • Study Sample Problem 9.1 on page 275 and then show your work for practice problem I9-34 (In chapter 9, problem 34) .
  • In the Section Assessment 9.5 on page 279, read, analyze, and show your work for practice problems I9-35 (In chapter 9, problem35), I9-36, I9-37, I9-38ab, I9-39abc, I9-40ab, and I9-41abcd.
  • Study Conceptual Problem 10.5 on page 298 and then show your work including all conversion ratios for practice problems I10-16 (In chapter 10, problem 16) and I10-17.
  • Study Conceptual Problem 10.6 on page 299 and then show your work including all conversion ratios for practice problems I10-18 (In chapter 10, problem 18) and I10-19.
  • Study Conceptual Problem 10.7 on page 301 and then show your work including all conversion ratios for practice problems I10-20ab (In chapter 10, problem 20ab) and I10-21ab.
  • Study Conceptual Problem 10.8 on page 302 and then show your work including all conversion ratios for practice problems I10-22 (In chapter 10, problem 22) and I10-23.
  • In the Section Assessment 10.2 on page 303, read, analyze, and show your work including all conversion ratios for practice problems I10-24, I10-25, I10-26, I10-27, I10-28, I10-29, I10-30abc, and I10-31ab.
  • After you are finished, check page R90 of the text and check each of those problems that you can by writing in either a check mark (√) or a correction in green ink as we do in class.   Some questions do not have a suggested response given.  For each such question, circle the number of the question in the margin of your notebook paper and check your response with that of your classmates when you come to class.

Recommended for those who have time left in their 45 minute study period, but not required of all:

1.  Open the Unit Learning Objectives for Cornell Notes document, Press and hold the CTRL key while typing F to bring up a search (find) box.  Type in Chapter 10 in the search box and then move your cursor into the text area to the right and click there to see the first page of objectives.  Consider each chapter 10 learning objective as you proceed through the chapter with the aim of being able to demonstrate your understanding and ability to apply the learnings.  Study and take Cornell notes on objectives 3 through 14.  

2.  Download the flipchart on chemical quantities after clicking on the following link: Chemical Quantities.  Click through the chart quickly and take Cornell notes on concepts pertaining to the learning objectives that you are studying.   At the end of your study, write a summary statement of what you learned.
