How much energy must be removed to convert 9.73 g of water at
20.9 oC to an ice cube at -12.0 oC? Give your answer as a positive
value in Joules since only positive energy can be removed.. cwater
= 4.184 J/goC, cice = 2.03 J/goC, ΔHfus, water = 6.01 kJ/mol

How much energy must be removed from a 125 g sample of benzene
(C6H6) vapor at 425.0 K to make it a solid at 200.0 K? Use the
following steps to get to your answer. You MUST show your work to
receive any credit. The following physical data for benzene may be
useful. The quiz will be due at the beginning of class on 2/17/16.

Suppose that you must decide how much to work. Using the idea
that the labor supply decision results from a trade-off between
leisure and income, answer the following questions. 1. Define the
problem that you must solve to figure out the optimal amount of
leisure and hours worked. 2. Derive the first-order condition for
your optimal decision. 3. Show why the labor supply curve slopes
upward with respect to the real wage. 4. Suppose that the real wage
falls from...
