1. hydrochloric acid solution with a specific gravity = 1.12. stated that the concentration of hydrochloric acida. molarityb. % By weight per volume
A mixture contains only NaCl and Fe(NO3)3. A 0.456-g sample of the mixture is dissolved in water, and an excess of NaOH is added, producing a precipitate of Fe(OH)3. The precipitate is filtered, dried, and weighed. Its mass is 0.107 g.
1) Calculate the quantity of pure make up oxygen to be supplied, (in kg/h), in steady state operation.
What is element X? Propose a name for H2X? To completely neutralize a sample of H2X, 35.6 mL of 0.175 M OH solution was required. What was the mass of the H2X sample used?
Design a Heat Exchanger for the Following Duty: Reduced crude oil leaving a distillation unit with a flow rate of 3166.04 kL/d at 268 oC and is to be cooled to 243 oC by exchange with 62.8 kg/s pre-flashed crude oil coming from pre-flash unit at 206 ..
The organic solution is evaporated to dryness and then the product is purified by chromatography in methanol over aluminum oxide or silica gel. Sketch a block flow diagram of the process.

Problem 1: For the circuit given in Figure 1 the power factor is 0.72 lagging and the power dissipated is 375 W.
12. Comparing emitted Auger electrons (AES, Auger electron spectroscopy) with X-rays (EDX / EDS, energy-dispersive X-ray spectroscopy), what is the difference in the analysed sample volume (i.e. volume of the sample from which the signal comes)?
Hydrogen is manufactured from methane by either steam reforming (reaction with steam) or partial oxidation (reaction with oxygen). Both processes are endothermic. What reactor temperature and pressure would you expect to be optimal for these proce..
Adipic acid is used in the manufacture of nylon 6,6. It is made by hydrogenation of phenol to a mixture of cyclohexane and cyclohexane (known as KA oil-ketone and alcohol), followed by oxidation with nitric acid.
During the research that led to production of the two atomic bombs used against Japan in World War II, different mechanisms for obtaining a supercritical mass of fissionable material were investigated.
