IB Chemistry
Redox Extra-credit (due before the Holiday break on December 20):Research 1 specific type of battery (for example D-cells, car batteries, fuel cells, solar panels, AAA, Lithium battery) and make either a mini-poster or pamphlet explaining the CHEMISTRY of how it works.
In class right now it's.... THERMOCHEMISTRY! That means heat changes in chemical reactions. You'll be learning about how and why reactions change heat, plus how to calculate the heat change in a process using calorimetry, Hess's Law and Bond energies.
You'll also be doing your big IA: Investigate 1 factor which affects that results of a calorimetry experiment. You can use either the burn-under-water technique or the reaction-in-a-cup technique to find the affect of one factor on the calculated heat change. This is a FULL IA, will all 3 sections, due December 19. Fun!
Chemistry
Bond Test Thursday 12/12! You've been learning about ions, names and formulas for ionic compounds, covalent bonding, Lewis Dot structures, VSEPR shapes, and intermolecular bond strengths. Whew! But, the ionic names and formulas are by far the most important part. That is the section which will carry through into other units and is the section which carries the most weight on the test.
Next up, you finally get to learn about.... THE MOLE!
