Commercial cold packs and hot packs are available for treating athletic injuries. Both types contain a pouch of water and a dry chemical. When the pack is struck, the pouch of water breaks, dissolving the chemical, and the solution becomes either hot or cold. Many hot packs use magnesium sulfate, and many cold packs use ammonium nitrate. Write reactions to show how these strong electrolytes break apart when they dissolve in water.
Gas Absorption and Transfer Operations: Column Diameter Calculation, A gas absorption column to handle 3630 kg/hr of a gas is being designed. Based on pressure drop, entrainment and foaming considerations
Solid NH4NO3 (ammonium nitrate) decomposes on heating to 400°C, forming N2O gas and water vapor, H2O. (a)Write a balanced chemical equation
Develop a process schematic. Assume that this process is continuous. Show each product stream illustrating the impurity level with respect to the feed entering the particular separator.
why a substance is being heated at a fast rate the temperature of decomposition will be the higher than the obtain at a
Methyl ethyl ketone (MEK) is manufactured by the dehydrogenation of 2-butanol using a shell and tube type reactor. Flue gases are used for heating and pass though the tubes. The flue gases will contain traces of sulfur dioxide.
Into a barrel containing 33.2 bbl (US) of water containing 0.0012 mol/L of a blue dye you pour V2 yd3 of water containing 8.91 M of the dye. The final concentration of the dye in the barrel is 7.91 mol/m3 after it's well-mixed. What is V2 is yd^3?
It is desired to use 28.32 m 3 /min of air (metered at a pressure of 101.3 kPa and 294.1 K) in a process. This amount of air which is at rest enters the fan suction at a pressure of 741.7 mm Hg and a temperature of 366.3 K and is discharged at a pres..
A gas mixture containing 55 mol% propane and 45 mol% propylene is to be separated into products containing 10 and 90 mol% propane by adsorption in a continuous, countercurrent adsorption system operating at 25°C and 1 atm. The adsorbent is silica ..
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.
Assume you have gas in a cylinder equipped with a piston. There are weights on the piston creating pressure down on the gas.
Natural gas composed of 60. mol% methane, 30. mol% ethane, and 10. mol% propane at 25 °C and 500. psia is fed at a rate of 50. m3/hr into a boiler. In the boiler it is blended with enough air to provide 20% excess oxygen and combusted.
