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...

LARN 122 C31D2 Start the following in class: 1.a.  Solvation is the process of solute particles becoming surrounded by solvent molecules which are attracting the solute particles through "intermolecular forces of attraction".  The term intermolecular forces of attraction includes not only London dispersion force attractions but also includes ion-dipole interactions and dipole-dipole interactions.  If the solvent is water, the solvation process can be called hydration. Examine the  different animation action close ups of formula units of a substance dissolving at  https://www.youtube.com/watch?v=EBfGcTAJF4o https://www.youtube.com/watch?v=CLHP4r0E7hg https://www.youtube.com/watch?v=zePYWZ2AjnI https://www.youtube.com/watch?v=IPQzY34eCt4 https://www.youtube.com/watch?v=aKGJm6OGJNs https://www.youtube.com/watch?v=xdedxfhcpWo https://www.youtube.com/watch?v=JAWiJKhmbQc  List some things wrong with the previous simulations of dissolving salt Salt vs. Sucrose Note:  One must wait for each animation to be over before the buttons for the other animations appear. The required focus topics, J122A for today are a. Describe the process of an ionic solute such as sodium chloride, NaCl, dissolving in water and making an aqueous sodium chloride solution.  Please make your answer to this question longer than one sentence. b. Construct two or more well labeled...

LARN 121 C31D1 Start the following in class: 1. The required focus question, J121, for today is: Anomalous means unusual.  Hydrogen bonding within a substance may be the cause of anomalous properties exhibited by the substance.  Construct a numbered list of six (6) of the properties of water that result from the ability of its molecules to hydrogen bond to one another in multiple directions. 2.a. Use the PQ5R or SQ5R method to prepare study guide for text section 15.1 on Water and Its Properties or go to https://socratic.org/chemistry  to research the topics brought up in section 15.1 of your text. .  Read section 15.1 in your chemistry text, pages 444 through 449, 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...
