Pre-class reading quiz on Chapter 12
Last day I asked at the end of class:
Why did that
We consider only rigid (non-squishy) bodies in this
We have already studied translational motion in
considerable detail. We now know that the trans

Acid-Base Equilibrium and Buffers
The purpose of this lab was to determine the room temperature equilibrium constant for
the reaction between Fe3+ and SCN-, to form the complex ion, FeSCN2+ in an acidic
Experiment 7 Determination of pKa of an Unknown Indicator
Purpose: The experiment is aimed to determine the alkalinity of unknown aqueous
solutions using a double endpoint titration for determination of [OH-] and [CO3-].
pKa of an Unknown Acid-Base Indicator
The purpose of this lab is to determine the pKa of un unknown acid-base indicator using
UV-visible spectroscopy to quantify the concentration and the molar extinction
In Parts A, B, C consider the following situation. In a baseball game the batter swings and gets a good
solid hit. His swing applies a force of 12,000 N to the ball for a time of 0.70103s.
Assuming that this force is constant, what is the magnitude
