Today was a typical Monday, as we began each class with oral summaries of science news articles. We discussed a portion of Section 3-3 notes on how chemical symbols and subscripts are used to create a chemical formula to represent a compound. Students learned that some elements get their chemical symbols from their Latin name. I demonstrated how to count the number of atoms in a chemical formula, including those with parentheses. Students then were assigned problems 1-10 on worksheet 3-7. We reviewed the answers using the student responders together. Students were then assigned the remaining 10 problems (#11-20) to work on for the remainder of the period.
No homework was assigned, and the Chapter 3 test will be on Thursday, December 9th.
