Class of: 18-Feb-2016.
(I didn’t get to this yet in Block B. Don’t worry, we will catch up!)
Today we covered Section 8.2: Another Look at Bonding – Lewis Diagrams (p. 210).
Learning Objectives:
- Students will be able to draw Lewis diagrams to represent atoms, molecules, and ions.
Your body cannot dissolve all of chewing gum! The digestive system is able to absorb the sugar and flavourings used, but the gum resin itself does not dissolve in the acid. The resin used to be made of sap from the Sapodilla tree, but now synthetic materials are used. For example: butyl rubber, which is also used to make inner tubes! Acids dissolve things by reacting the H+ ions with the material to break its bonds and therefore break it apart, and stomach acid is not strong enough for the H+ ions to react with the rubber.
Have a fantastic long weekend!!!
