1. What power is required to drive a reversed Stirling cycle heat pump with a high-temperature heat transfer rate of 14.0 kW over the temperature difference 30.0°C and 0.00°C, if the actual coefficient of performance is 50.0% of the ASC coefficient of performance for this unit?
2. Determine the cooling temperature and the coefficient of performance of an isenthalpic expansion cooler that expands air from 1500. psia, 70.0°F to 14.7 psia. The isentropic efficiency of the compressor is 85.0%. The mean Joule-Thomson coefficient for this process is 0.0200°F/psi.

What volume of .250 M calcium chloride would be required to precipitate silver chloride if it is mixed with 600.0 ml of 0.650 M Silver nitrate.
Explain a compound contains only carbon, hydrogen and oxygen. Combustion of 0.01068 g of the compound yields 0.01601g CO2 as well as 0.00437g of H2O. The molar mass of the compound is 176.1g/mol. Define what are the empirical and molecular formula..
Given that the ionizable H atoms are associated with carboxyl groups, draw a plausible structure for maleic acid.
Rank the substituents shown below in order of Cahn-Ingold-Prelog priorities (1 = highest priority group, 4 = lowest priority group).
Problem- Calculate the radiation dosage (in grays) for an 77-kg person that is exposed for 3.0 seconds to a 3.0 Ci source of beta radiation. Assume that 100% of the radiation is absorbed and each beta particle has an energy of 2.0×10-13 J.
