Consider 1.5 kg of austenite containing 1.15 wt% C, cooled to below 727 degrees Celcius (1341 degrees Farenheit).
a) What is the proeutectoid phase?
b) How many kilograms each of total ferrite and cementite form?
c) How many kilograms each of pearlite and the proeutectoid phase form?
d) Schematically sketch and label the resulting microstructure.
Given stock solutions of glucose (1M), asparagine (100 mM), and NaH2PO4 (50 mM), how much of each solution would you need to prepare 500 mL
In May 1990 the French TGV train traveled the distance from Paris to Lille, France (127 miles) in .819 hours. What was the speed of the TGV in m/s?
A 0.456 gram sample of an unknown monoprotic acid (lets call it HZ) was dissolved in some water . Then the acidic solution was titrated to the equivalence point with 32.5 mL of 0.174 M KOH.
The flow rate of a process stream of hydrogen at 50 degrees celcius and 1800 mmhg, and the value read from the calibration chart is 350 cm^3/s. Calculate the true volumetric flow rate of the gas.
Determine the mass of acetamide present per kg of water if the freezing point of this solution is 0 °C. (The freezing point of pure water is 0°C (exactly) at 1 atm pressure and the molal freezing-point-depression constant for water is 1.86°C/m.)
with this balanced equation of copper carbonate calculate the concentration of copper in solution
How much heat must be applied to a 18.3 g sample of iron (s=0.449J/(g x *C) in order to raise its temperature from 23.8*C to 356.6*C
Express the pressure values numerically in atmospheres, separated by commas. Enter the partial pressure of methane first, then ethane, then propane.
What mass of sucrose should be combined with 464 g of water to make a solution with an osmotic pressure of 8.35 atm at 320 K? (Assume the density of the solution to be equal to the density of the solvent.)
A 300.0-mL saturated solution of copper(II) peroidate (Cu(IO4)2) contains 0.44 grams of dissolved salt. Determine the Ksp.
At what temperature is the change in entropy for the reaction equal to the change in entropy for the surroundings?
