Fri-Day 1
Bio 3/6: took our first unit exam and then finished our discussion of the microscopy lab.
AP Chem- We balanced the equation from our previous combustion analysis problem. Remember, always balance the "free" elements, if any, last.
We did a complex problem showing gravimetric analysis in order to determine the identity of an unknown element in a compound. Video tutorials of gravimetric analysis will be posted on Blackboard.
