1. Wet air containing 4.0 mole% water vapor at 76°F and 14.8 psia is passed through a column of calcium chloride pellets. The pellets absorb 97% of the water and none of the other constituents of the air. The column packing was initially dry and had a mass of 3.40 kg. Following 5.0 hours of operation, the pellets are reweighed and found to have a mass of 3.52 kg. Calculate the molar ?ow rate (mol/h) of the feed gas and the mole fraction of water vapor in the product gas.
2. Ammonia is burned with oxygen to form nitric oxide (NO) and water.
a) Calculate the ratio (lbmole O2 react/lbmole NO formed).
b) If ammonia is fed to a continuous reactor at a rate of 100 kmol NH3/h, what oxygen feed rate (kmol/h) would correspond to 40.0% excess O2?
c) If 50.0 kg of ammonia and 100.0 kg of oxygen are fed to a batch reactor, determine the limiting reactant, the percentage by which the other reactant is in excess, and the extent of reaction (mol) and mass of NO produced (kg) if the reaction proceeds to completion.
what are the laboratory apparatuses used in inorganic chemistry ?
which metal is highly reactive?
introduction
Non-benzenoid aromatics and Heterocyclic compounds There are aromatic compounds that have structural units which are not same from benzenoid type and are termed as Non-benzeno
a. Calculate the global radiation density (kWh/m 2 ) received by five panels located in San Jose on July 1, 2012: Panel A: Tilt=37.3 o , Azimuth=180 o (South) Panel B: Ti
name the physical state of matter which can be easily compressed.
Why secondary and tertiary amine doesn''t give carbylamine reaction
It can be because these group tend to decrease the electron density when attached to a benzene or other ring structure preferentially at ortho and pera position.
factors that effect the solubility of a solute The solubility of a solute is effected by three factors like 1) Nature of solute 2) Nature of solvent 3) Temperature Nature
