Chemistry 11:  I collected any remaining Lab 6A and 6Bs.  Today we titrated a solution of HCl to determine its unknown concentration.  Terrific work on your very first titration!  We spent time completing Lab 20C Questions and Calculations # 1-3, and working on the various Stoichiometry skill building exercises listed below.  These items need to be in your binder, ready to show me that you have been building your skills.

A)  Stoichiometry Involving Limiting Reactant (WS, white, key posted at the side)
B) Stoichiometry Calculations (WS, white, legal sized, key posted at the side)
C) Hebdon Unit 7 # 8 (answers in the back of your text)
D) Stoichiometry Calculations (WS, green, legal sized, key posted at the side table)

Science 10:  Today I collected any remaining Matching assignments and Lab 18E reports from Monday and Tuesday.  We read pg 234 to 238 and did pg 239 # 1-4,7,9 in fine sentences.  We reviewed atomic structure by making an atomic model on poster paper.  Everyone was assigned an isotope, except for one lucky student who was assigned Hydrogen-1, Hydrogen-2, and Hydrogen-3.  The instructions are written below in blue.

Create a mini poster showing the structure of an atom.  You will be assigned a particular atom of an element, called an isotope.

-show the placement and number of subatomic particles

-show a standard symbol for your isotope

-label the features on your standard symbol

-create a copy of Table 1 pg 156 (old Probe 10)

-have a large title, and put your name and date in the lower left corner
