Start the following in class:

1.  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 marginal line, print J75 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 topic J75 for today is:
  1. An Arrhenius acid is the water solution of a covalently bonded molecule that when placed in contact with water, produces H+(aq) ions as the only positively charged ions.  How are acids named?
  2.  Arrhenius binary acids are aqueous solutions that produce a monatomic cation and a monatomic anion.   Ternary acids are aqueous solutions that produce either a polyatomic cation or a polyatomic anion.  Write the formulas and names of three (3) binary acids and three (3) ternary acids.
  3. What similarities exist between the naming of binary acids and the naming of ternary acids?
  4.  All commonly occurring acids are weak except for seven strong ones.  Look up a page in the chapter 9 informational packet, and record the names and formulas of the seven strong acids into your journal.  Notice that the seven strong acids are associated with the elements nitrogen, sulfur, chlorine, bromine, and iodine which are adjacent to each other on the periodic table.  Learn the names and formulas of the seven strong acids by heart.

2.a. Use the PQ5R or SQ5R method to prepare a study guide for section 9.5 of your chemistry text on The Laws Governing Formulas and Names or go to https://socratic.org/chemistry to research the topics brought up in section 9.5 of your text.  Read section 9.5 in your chemistry text, pages 274 through 279, 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 9 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.

  • After you are finished, check page R89 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 9 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 9 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 objective 13. 

2.  Do both sides of the worksheet entitled Chemical Names and Formulas skillsheet printed in your chapter seven learning packet but also available online.
