Honors chem Goes viral


So today we started with a demo that was pretty awesome. 

The reaction taking place was
Pb(No3) + KI
This is lead nitrate and potassium Iodide
So back to what happened. the molecular formula for this reaction was PbI2(s) + KNO3
This is then balanced to Pb(No3) + 2KI --------> PBI2 + 2KNO3
The NIE was Pb^+2 + 2I- -------> PbI2(s)

That was pretty much our day after that we worked on the worksheet that can be found here and the lab which can be found here
Things you might want to know - Hali = ion form of a halogen
and there is a review sheet up here
After that we had some tough decisions to make because when our video goes viral we need a name and a mascot. We decided on Chris as our mascot ( the shirts we make will have his face on the back) and we havent came up with a good name, but we will. Tomorrow in class will be a review for the test on unit 4. Bring questions about the book problem,labs, worksheets and anything else about the unit.
Our next scribe is Sarah. Have fun.
