LARN 123 C31D3
Start the following in class:
1.a. Write your first 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, write your hand in number within a circle followed by your name. 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 days paragraph with a topic sentence, follow with explained instances, and close with a focused summary statement. .
The required focus topic, J123A, for today is
A hydrate is a substance that contains a definite composition including a definite composition of water within the crystals which are dry to the touch.
- Give an example of an efforescent hydrate and describe the unique behavior that makes it efflorescent.
- Give an example of a hygroscopic compound and describe the unique behavior that makes it hygroscopic.
- Describe two uses of hygroscopic compounds.
- Give an example of a deliquescent compound and describe the unique behavior that makes it deliquescent.
- Compare and contrast efflorescent hydrates and hygroscopic compounds. Please make your answer to this question longer than one sentence.
- Compare and contrast hygroscopic compounds and deliquescent compounds. Please make your answer to this question longer than one sentence.
1.b. 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, write your hand in number within a circle followed by your name. 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 days paragraph with a topic sentence, follow with explained instances, and close with a focused summary statement.
The second required focus topic, J123B, for today is
- Compare the typical particle sizes found in solutions, colloids, and suspensions.
- Predict whether solutions, colloids, and suspensions exhibit the Tyndall effect and explain why each does or does not. Refer to the above listed examples to clarify each idea that you express in your learning journal and explain how each example demonstrates the concept being considered.
- Predict whether solutions, colloids, and suspensions exhibit Brownian motion and explain why each does or does not. Refer to the above listed examples to clarify each idea that you express in your learning journal and explain how each example demonstrates the concept being considered.
2.a. Use the PQ5R or SQ5R method to prepare study guide for text section 15.3 on Heterogeneous Aqueous Systems or go to https://socratic.org/chemistry to research the topics brought up in section 15.3 of your text. . Read section 15.3 in your chemistry text, pages 459 through 464, 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 15 vocabulary list that was distributed 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 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.
- In the Section Assessment 15.3 on page 462, read, analyze, describe and explain practice problems I15-16 (In chapter 15, problem 16) and I15-17, I15-18; I15-19ab; I15-20; I15-21abc.
After you have written your best effort response for each assigned item, check page R94 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.
Recommended for those who have time left in their 45 minute study period, but not required of all:
1. Continue to review the meanings of the words on the chapter 1, chapter 2, chapter 3,chapter 4, chapter 5, chapter 7, chapter 8, chapter 9, chapter 10, chapter 11, chapter 12, chapter 13, chapter 14, and chapter 15 vocabulary lists. Place a – symbol in front of each word that you have to study more,and a change the- to a + symbol in front when you have demonstrated mastery over the word to a study buddy, parent, or friend..6. Study the Key Concepts given on pages 33, 57, 95, 121, 148, 180, 206, 246, 280, 314,346, 378, 406, 438, and 464 of the text.
2. Review those concepts that we have discussed in class that are in your study guides, that are in your text study guide at the end of the chapter, and that on the chapter vocabulary sheet provided to you that describes what is a substance, an element, a compound, a coarse mixture, a colloidal suspension, a solution; an atom; a formula unit, a molecule;a phase, an aqueous phase; a chemical change,a physical change;a chemical reaction, a reactant, a product, a word equation, and a formula unit equation;and how are these concepts different? You need to be able to explain the meaning of each of these terms, and be able to differentiate the terms, be able to compare and contrast these related terms, and give examples that make clear the points that you are trying to explain. Go over each of these concepts with your study partner.
