LARN 133 C34D1

Start the following in class:

1.  Write your first journal entry for today, J133A,  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.

Read pages R36 and R37 on the properties, and sources of the elements helium, neon, argon, krypton, xenon, and radon found in Group 18 (VIIIA). In your learning journal  record the answers to these three numbered questions:

  1. What is the most interesting fact you read about?    Please make your answer longer than one sentence.
  2. What makes this so interesting to you?   Please make your answer longer than one sentence.
  3. What is one use for one of the aforementioned nonmetals that you either were not familiar with or were least familiar with?  Please make your answer longer than one sentence.

2.  Do all the pages in the Section Review packet for chapter 16, Solutions 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 section review packet for the chapter in class or if you have misplaced it, go to MNSD Google Drive > Student Resources > Section Reviews and print off a section review for each individual section of the chapter.
  • The section review packet for each chapter contains a separate section review document for each section of the chapter.  So for example, a chapter with four sections would have four separate section review documents that need to be printed off.  Each section review question document is identified by a name whose last two digits or last three digits represent the chapter number followed by the section number of that particular section. So for example, chsr153.pdf stands for chapter section review for chapter 15, section 3.
  • 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.

After doing this formative assessment, but before you demonstrate your understanding on our class’ summative assessment, you will check all your responses using green ink check marks, √, for each correct response, and by lining out (striking trough) and inserting improved text in green ink when you think the suggested response expresses your present understanding in a better way.  Then, when you know what you didn’t understand, you will be able to study more efficiently by studying that which you have corrected in green ink.

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

1.  For your second learning journal entry, J133B, on your three holed 8.5 inch by 11 inch ruled paper, you are to construct a concept map.  Please turn to page 498 in your text and, in your learning journal, construct a concept map relating the following seventeen terms:

  • concentration,
  • molarity,
  • molality,
  • moles of solute,
  • volume of solution,
  • mass of solvent in kg,
  • solubility,
  • soluble,
  • slightly soluble,
  • insoluble [or very slightly soluble],
  • saturated solution,
  • unsaturated solution,
  • supersaturated solution,
  • colligative property,
  • vapor pressure lowering,
  • freezing point depression, and
  • boiling point elevation.

Connect related terms with 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 arrow head is touching the oval of the term which is the object or predicate nominative of the verb that you have chosen.

2. Read and study the Study Guides given on pages 33, 57, 95, 121, 148, 180, 206, 246, 280, 314, 346, 378, 406, 438, 464, and 498 of the text.  Review the Key Concepts for each text section and clarify in your mind under what circumstances would it be helpful to use each of the different relationships shown in the Key Equations section.

3.  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.

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