Voltmeter Switch KNO, Salt Bridge Sn 1.0 M Cu(NO,)2 1.0 M Sn(NO,2 2) The voltaic cell pictured above is constructed with electrodes of known mass. The switch is closed and the cell is allowed to operate for a period of time. At that point, the electrodes were rinsed, dried, and massed and it was discovered that the copper metal had a higher mass than it initially had. a) Which metal is the anode? b) Which metal is the cathode? c) Write the half equation for the process that occurs at the anode. d) Write the half equation for the process that occurs at the cathode. e) Write the overall equation for the reaction. f) Will electrons flow from the copper electrode to the tin electrode or from the tin to the copper? g) Which half-cell will show an increase in the K* concentration over time? h) Which half-cell will show an increase in the NO, concentration over time? i) What happens to the concentration of Sn*2 as the cell operates?

A bicyclist is stopped at the entrance to a valley, as sketched below: B D Where would the bicyclist have the highest potential energy? Where would the bicyclist have the lowest potential energy? Where would the bicyclist have the highest kinetic energy? Where would the bicyclist have the highest speed? Would the bicyclist's kinetic energy be higher at C or B? Would the bicyclist's potential energy be higher at C or B? Would the bicyclist's total energy be higher at C or B? Suppose the bicyclist lets off the brakes and coasts down into the valley without pedaling. Even if there is no friction or air resistance to slow her down, what is the farthest point the bicyclist could reach without pedaling?
