LARN 152 C38D4

Start the following in class:

1. Write your journal entry on sheets of three holed 8.5 inch by 11 inch ruled paper in your Journal notebook. In the upper right corner white space of each upward facing page, write your hand in number within a circle followed by your name. For today’s journal entry, J152, you are to construct a concept map.  Please turn to page 580 in your text and, in your learning journal, construct a concept map relating the following nine terms:

  • entropy,
  • enthalpy,
  • free energy,
  • change in Gibbs free energy,
  • change in enthalpy,
  • change in entropy,
  • law of disorder,
  • nonspontaneous reaction,
  • spontaneous reaction.

Copy the terms onto your page, draw ovals around each term, and connect the ovals surrounding related terms with arrows.  Draw the arrows such that the subject of each sentence explaining the relationship is at the tail of the arrow, the verb describing the relationship of the subject to the predicate is written beside the arrow, and the object or predicate nominative of the verb that you have chosen is being touched by the arrow head.

2.  Do all the pages in the chapter 18 Test on Reaction Rates and Equilibrium as a formative assessment to find out some of the things that you do and do not know, and not as a research project.

  • If you did not obtain a formative test packet for the chapter in class, go to MNSD Google Drive > Student Resources > Formative Tests and print off a copy of the test for the chapter you are studying.  Each chapter test is identified by a name whose last two digits is the chapter number.  For example, the chcta16.pdf designates the chemistry chapter 16 test “A”.  When the chapter formative test is opened, the first page will have the words “Chapter Test A” in the title.
  • For each question or problem challenge for which a work space is given, either answer the question to the best of your ability using one or more full sentences, or answer the problem to the best of your ability by recording the numbers and units of measure of what is sought for, of what was given, and of what, if any, conversion or comparison ratios could be used to obtain a correct solution.  Circle or box your final result after expressing your result to the proper number of significant figures, followed by the proper unit of measure.
  • Each formative test is a real chapter test that some teachers in other schools might use as a chapter test, so after taking the test, make sure that you understand each unfamiliar word, idea, concept, and problem.  Be sure to finish this packet in its entirety.  After doing the formative assessment, but before you demonstrate your understanding on our class’ chapter summative assessment, you will check all your responses using green ink check marks (√) for each correct response, and by lining out (striking through) and inserting improved text in green ink when you think the suggested response expresses your present understanding in a better way.   While doing that, make sure that you understand each idea that you originally did not have a complete understanding of.  Then you will be able to study more efficiently by studying that which you corrected in green ink.

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, chapter 15, chapter 16, chapter 17, and chapter 18 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.

2. Study the Key Concepts given on pages 33, 57, 95, 121, 148, 180, 206, 246, 280, 314, 346, 378, 406, 438, 464, 498, 534, and 580 of the text.

3.  Study the Unit Analysis Strategy document for solving problems.  Learn the numerator and denominator units of the named conversion ratios to make problem solving easier for you.

4.  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.  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.

5.Review the SI prefixes and their meanings until you can readily explain the meaning of each listed SI prefix as a numerical multiplier.

6.Check out the student made Quizlet at Chapter 18 Vocabulary.  Do all the definitions reflect a thorough and correct understanding?
