If the total composition of the mixture is 10. mol% carbon monoxide, what will bethe pressure limits of VLE for this mixture at 25°C?

A passive solar house was determined to lose heat to the outdoors at an average rate of 50,000
kJ/h during a typical 10-hour winter night. The house is to be maintained at 22°C at all times.
Passive heating is accomplished by 50 glass containers each containing 20 L of water that is
heated to 80°C during the day by absorbing solar energy. A 15-kW back-up electric resistance
heater turns on whenever necessary to keep the house at 22°C. (a) How many hours does the
electric heating system run during a typical winter night? (b) How many hours would the
electric heater run during a typical winter night if the house did not
have passive solar heating? For the density and specific heat of water
at room temperature, use p = 1 kg/L and cp = 4.18 kJ/kg.°C
A well-insulated rigid tank contains 3 kg of a saturated liquid-vapor
mixture of water at 200 kPa. Initially, three-quarters of the mass is in the liquid phase. An
electric resistance heater placed in the tank is now turned on and kept on until all the liquid in
the tank is vaporized. Determine the entropy change of the water during this process.

At the Paso Robles Wastewater Treatment plant, they add MgCl2 to the pressate (concentrated liquid pressed from sludge) to precipitate phosphate as the mineral struvite. Struvite is formed by the reaction of phosphate with magnesium ions and ammonium, and the solubility product for struvite is 5.5x10-14. The ammonium concentration is very high at 300 mg N-NH4/L because the sludge is coming from an anaerobic digester.
