1. A student attempts to identify an unknown compound by the
method used in this experiment. She finds that when she heated a
sample weighing 0.5015 g the mass went down appreciably, to 0.3432
g. When the product was converted to a chloride, the mass went up,
to 0.3726 g.
a. Is the sample a carbonate? ____________ Give your
reasoning.
b. What are the two compounds that might be in the unknown?
____________ and ____________
c. Write the chemical equation...
1. What is the role of the capture antibody in the
ELISA?
2. How is a colored reaction product produced in the
ELISA?
3. What is the role of the Abeta standard curve in the
ELISA?
1. Explain how rules are used to facilitate communication.
2. Explain the role of protocols and standards organizations in
facilitating interoperability in network communications.
3. Explain how devices on a LAN access resources in a small to
medium-sized business network.

How is the discrete choice experiment method different from the
contingent valuation method? What are some relative advantages of
the discrete choice experiment method as compared to the contingent
valuation method? Can you think of any examples where the
contingent valuation method may be more practical than the discrete
choice experiment method?

Water enters the condenser of surface type; the temperatures of
the water that is used to cool the steam is 17oC and 28oC
respectively. The pressure of the condenser is at 0.055 bar and
0.87 dry fraction. The overall heat transfer coefficient in the
condenser is 3 kW/m2.oC. The condenser has three passes and tubes
used have 17.6 mm internal diameter and 20 mm external diameter. If
the flow area is 1.3 m2, Design the condenser. If the condenser is...
