The addition of an oxidizing agent such as chlorine water to a clear solution of an unknown compound results in the appearance of a brown color. When this solution is shaken with the organic solvent, methylene dichloride, the organic solvent layer turns purple. The unknown compound probably contains
(A) K+
(B) Br¯
(C) NO3¯
(D) I¯
(E) Co2+
The chemical reactor shown below has a cover (called a head) that is held in place by a series of bolts. The head is made of stainless steel (SG = 8.0), is 3 in. thick, has a diameter of 24 in., and covers and seals an opening 20in. in diameter.
The total volume of hydrogen gas needed to fill the Hindenburg was 2.0 108 L at 1.0 atm and 25C. How much heat was evolved when the Hindenburg exploded, assuming all of the hydrogen reacted?

Write reactions for which the enthalpy change will be a. Hf for solid aluminum oxide
Calculate the tower height, Z, and tower diameter, D, needed so that the Z/D ratio is about 4 and at this optimum condition, what are the values of f, Tez, and air flow rate, G?
The heat of formation of (NH4)2SO3 (aq) at 25°C is -890.0kJ/mol, and that of NH4HSO3 (aq) is -760 kJ/mol. The heat capacities of all liquid solutions may be taken to be 4.0 J/(g*°C) and that of the flue gas may be that of nitrogen. Evaporation of ..
Chlorine has two isotopes 35Cl and 37 Cl, for the anion Cl- , of the isotope 37 Cl, specify the number of protons np ,number of electrons ne and numbers of neutrons nn
(a) The safest conditions are achieved by the lowest temperature and pressure in the flash vessel. (b) Vapor flow to downstream equipment can cause a hazardous situation.
A vapor rate of 2500 kg/h is required and the vaporizer will operate at 6 bara. Size the vessel to restrict the carryover of liquid droplets. The liquid hold-up time need not be considered, as the liquid level will be a function of the thermal des..
