Two streams of air are mixed in a steady-state process shown below. Assume air is an ideal gas with a constant heat capacity CP = 7R/2. The Stream in are: Stream A = 0.167 mol/s, 250K, 1 bar Stream B = 0.8333 mol/s, 310 K, 1 bar The Stream out is: Stream C = 1 bar 1.) What is the temperature of the stream leaving the tank? 2.) What is the rate of entropy generation within the tank? 3.) If we duplicated the stream conditions (temperatures, pressures, and flowrates) with an internally reversible process, what is the maximum rate at which work could be obtained? If desirable, you are permitted to transfer heat to the surroundings at the surroundings' temperature of 295 K.
When heated, lithium reacts with nitrogen to form lithium nitride. What is the percent yield of the reaction if 13.9 of Li is heated with 33.3 g of N2 and the actual yield of Li3n is 6.64 g?
Molecules can be as small as a few atoms or as large as thousands of atoms. In 1962, Max F. Prutz and John C. Kendrew were awarded the Nobel Prize for their discovery of the structure of hemoglobin.
a main component of photochemical smog. Classify this reaction as a synthesis, decomposition, single-displacement, or double-displacement reaction.
Draw all stereoisomers having molecular formula C6H12 that contain one double bond and give the IUPAC name for each compound.
you purchase a cup of coffee, but, at 98.4 degrees C, it is too hot. You add 45.5 g of ice that is -2.2 degrees C to the 248ml of coffee. What is the final temperature of the coffee?
How many grams of CaCl2 would be required to produce a 3.5 M (molar) solution with a volume of 2.0 L.
What mass of calcium metal could be obtained from one kg of limestone that is 50.0% pure CaCO3?
The rate of a chemical reaction can sometimes be determined by measuring the change in mass of the reaction flask and its contents with time
If 1.50 g of (NH4)2SO4 is dissolved in enough water to form 200. mL of solution, what is the molarity of the solution.
What time will it take 10.0 mL of Chlorine gas to effuse through a porous barrier when it has been noticed that 76.3 min are needed for 10.0 mL of Hydrochloric acid gas to effuse through the same barrier.
Predict whether the entropy change in the system is positive, negative or close to zero for each of the following processes
We add excess Na2CrO4 solution to 17.0 mL of a solution of silver nitrate (AgNO3) to form insoluble solid Ag2CrO4. When it has been dried and weighed, the mass of Ag2CrO4 is found to be 0.310 grams.
