LARN 033 C9D1 Start the following in class: 1. The required journal focus question J33 for today is: What are the differences in the meanings of the terms a. atomic mass unit, u, b. isotopic mass, c. mass number of an isotope d. atomic mass of an element? 2.a.  Go to https://socratic.org/chemistry to research the topics brought up in section 4.3 of your text, OR use the PQ5R or SQ5R method to prepare a study guide for text section 4.3 on Distinguishing Among Atoms.  Read section 4.3 in your chemistry text, pages 110 through 119, 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 4 vocabulary list as you think about the meanings of the terms and add any notations to the vocabulary list for clarifications sake. 2.b. If necessary, review the instructions for doing in-chapter...
