Carbon black is produced by the decomposition of methane:
For equilibrium at 923.15 K (650°C) and 1 bar,
(a) What is the gas-phase composition if pure methane enters the reactor, and what fraction of the methane decomposes?
(b) Repeat part (a) if the feed is an equimolar mixture of methane and nitrogen.
You decide to take 2.00 mL of the solution and add an excess of a concentrated sodium chloride solution. You obtain a solid with a mass of 3.407 g. What was the concentration of the original lead(II) nitrate solution?
A suitable storage place must be geologically stable long enough for the activity of plutonium-239 to decrease to 0.1% of its original value. How long is this for plutonium-239?
Assume you. have a photodctcctor with a current rcsponsi vity of 5 AJW. A continuous wave HeNe laser with wavelength of 632.8 nm and spot size of 0.5 mm2 is incident on the active area of the detector. Assume that 6.37 x 1021 photons per m..
a. Estimate the feed flow rates of glycine and guaiacol that would be needed to produce 100 kg/day of the API. b. Estimate how much product is lost in the thin-film evaporator.
2 liters of N2 at 0 oc and 5 atm pressure are expanded isothermally against a constant external pressure of 1 atm until the pressure of gas reaches 1 atm. assuming gas to be ideal , calculate work of expansion
If 2.00 MNaOH is available, how would the student prepare the solution? To help insure three significant figures in the NaOH molarity, to how many significant figures should the volumes and mass be determined?
2. Alcohol is a diuretic agent, which increases urine production by reducing water reabsorption. Normal rate of water reabsorption is about 124 ml/min. Assume that the effect of alcohol on water reabsorption (in ml/min) is given by the following equa..
A larger distillation tower is needed for the same mixture, and it has been decided to use a 12-in. inside-diameter tower with the same type and size of packing.
Your painting showed a carbon-14 activity of 15.1 counts per minute per gram. Could it be a genuine Rembrandt?
Please answer these simple five questions on fabrication engineering at the micro and nanoscale.
One gram-mole of methyl chloride vapor is contained in a vessel at 100°C and 10atm. (a) Use the ideal gas equation of state to estimate the system volume.
