Le Chatelier lab / spontaneous reactions


Wednesday we will be putting LeChatelier's Principle into action in the lab. This will be a formal lab write-up -- follow this format I put on the board -- you will need 3 data tables -  one for each system - you must read the lab handout to determine what the stresses are - I have done the first system for you as an example and given you the number of stresses each system will have. 
The LeChats lab handout  --this is in the correct order too!
These are the follow-up questions for the lab - you may answer these in point form and you do not have to have completed the lab to do the sheet-- you can get started on them today! 

Today we also did a spontaneous reaction demo  - very cool chemistry in action -- 2 solids come together to form a liquid and a gas - and it is sooo endothermic it freezes a beaker to a wood block at room temperature!!  Block 3  students -- you will see this tomorrow! 
Attached is the sheet that goes with the demo.
