Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Gaseous propane (C3Hg) is burned in a steady-flow, constant-pressure process at 100 kPa with 200 percent theoretical air. During the combustion process, 90 percent of the carbon in the fuel is converted to CO2 and 10 percent is converted to CO. Use data from the tables. Determine the dew-point temperature of the products, in °C. (You must provide an answer before moving on to the next part.) °C. The dew-point temperature of the products is

On an uncomfortable summer day, the air is at 87 °F and 80 % relative humidity. A laboratory air conditioner is to deliver 1.0 x 103 ft3/min of air at 55 °F in order to maintain the interior air at an average temperature of 75°F and a relative humidity of 40%.

2. Tin (Sn) obeys Henry's law in dilute liquid solutions of Sn (solute) in Cd (solvent) and the Henrian activity coefficient of Sn, y°sn. varies with temperature as Ln y°su= -840/T+1.58 Calculate the change in temperature when 2 mole of liquid Sn and 98 moles of liquid Cd are mixed in an adiabatic enclosure. The molar constant pressure heat capacity of the liquid alloy formed is 29.5 J/K. a) Using the plot of XcuXFe Vs. log yCu below, a) Calculate the activity coefficient and activity of the Fe at X Cu =0.75 (write the equation for that). Use graphical approximate solution and explain briefly how you get it. b) Calculate the partial pressure of Fe over Cu-Fe liquid solution at Xcu-0.5 at 1550°C. Ln pFe ° (L) (atm) =-45390/T-1.27LNT +23.93 c) Does Cu-Fe liquid solution obey regular solution model? Show with at least three data.

Insulated Sample outside dish chamber [Review Topics] Burning Steel sample bomb Combustion (bomb) calorimeter. [References] In an experiment, a 0.6451 g sample of benzoic acid ( C7H6O2) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.397 x 10³ g of water. During the combustion the temperature increases from 24.07 to 26.49 °C. The heat capacity of water is 4.184 J-g¹. C-¹. Molar Heat of Combustion = The heat capacity of the calorimeter was determined in a previous experiment to be 883.5 J. °C-¹. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of benzoic acid based on these data. C7H6O2 (s) + (15/2) O₂(g) → 3H₂O(1) + 7CO₂ (g) + Energy kJ/mol
