Quarter 3 Blog January 30th, 2014

What we did in class? January 30, 2014

1. We first checked in homework (Mrs. Friedman gave credit to everyone who attempted the worksheets because she knew that they were challenging). 
2. Mrs. Friedman also announced that there will be a quiz tomorrow: 6 different Lewis Structures and deciding what the molecular geometry is. ( THERE WILL BE NO WEDGE/DASH ON THE QUIZ)
3. We got 3 new handouts ( which will be in the handouts folder on moodle). The titles of the worsheets are: VSEPR #3, valence shell electron pair repulsion(VESPR) Theory and the second page to this worksheet. 
4. Next we went over a few problems from the homework. ( A complete answer key to last nights homework will be posted in moodle). (BTW last nights homework was supposed to ask about clouds not pairs) for example it should say total electron clouds not pairs. 
5. We then completed yesterdays notes.( WHICH ALSO IS ON MOODLE) 
6. We also took some new notes about WEDGE AND DASH DRAWINGS.(ALSO ON MOODLE)
