LARN 098 C25D2
Start the following in class:
1. In your Journal Notebook write your journal entry J98 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 marginal line, print J98 and circle it.
- Each journal entry should either be at least a paragraph of exemplary writing and penmanship concerning a single topic, or be a concept map relating chemistry terms. Begin each day’s paragraph with a topic sentence, follow with explained instances, and close with a focused summary statement.
- The required journal focus topics, J98, for today are:
Many chemistry text books suggest that balanced equations can be interpreted in terms of
- numbers of formula units,
- numbers of moles of formula units,
- masses of the reactants and products, and
- volumes of reactant and product gases at standard temperature and pressure.
a. Which three of these four suggested interpretations can be read directly, without calculation, from the following balanced chemical expression without applying any calculations?
1 N2(g) + 3 H2(g) → 2 NH3(g)
b. In addition to the conservation of mass, are those three interpretations that you just cited justified in being called the primary relationships given by balanced chemical expressions? Why do you say so?
c. Use words to describe the following chemical equation on the level of formula units:
2 SO2(g) + 1 O2(g) → 2 SO3(g)
d. Use words to describe the following chemical equation on the level of moles of formula units:
2 SO2(g) + 1 O2(g) → 2 SO3(g)
2.a. Use the PQ5R or SQ5R method to prepare study guide for text section 12.1 on The Arithmetic of Equations or go to https://socratic.org/chemistry to research the topics brought up in section 12.1 of your text. Read section 12.1 in your chemistry text, , and as you do, create a study guide using the SQ5R or PQ5R method explained in class and on the distributed handout packet. Read section 12.1 in your chemistry text, pages 352 through 358, 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 12 vocabulary list as you think about the meanings of the terms and add any notations to the vocabulary list for clarifications sake.
2.b. 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 12.1 on page 355 and then show your work including all conversion ratios for practice problems I12-1 (In chapter 12, problem 1) and I12-2.
- If you need a refresher or assistance in writing conversion ratios and showing your work, please read through pages R66 and R67 and study how the conversion factors were selected, and set up so that the units in the problem divided out to yield the units of the sought for quantity. Note how the work shown completely explains how the six problems given on page R66 are solved.
- Study Conceptual Problem 12.1 on page 358 and then show your work including all conversion ratios for practice problems I12-3ab (In chapter 12, problem 3ab) and I12-4abc.
- In the Section Assessment 12.1 on page 358, read, analyze, and show your work including all conversion ratios for practice problems I12-5, I12-6, I12-7, I12-8, I12-9abc, and I12-10ab.
- After you are finished, check page R92 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. Download and 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 12 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 learning objective as you proceed through the chapter with the aim of being able to demonstrate your understanding and ability to apply the learnings. For now, study and take Cornell notes on objectives 3 through 5.
2. Download current ActivInspire unit flipchart by logging on to the MNSD Google Drive and selecting it from the Student Resources > ActivInspire folder. Generally the flipchart name will begin with a capital U to designate the chemistry unit of study and end in a relatively high version number following the v at the end of the flipchart’s title. Download the flipchart on stoichiometry after clicking on the following link: Stoichiometry . 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.
