In the chlorination of ethylene to produce dichloromethane (DCE), the conversion of ethylene is reported as 99.0%. If 94 mol of DCE are produced per 100 moll of ethylene reacted, calculate the selectivity and the overall yield based on ethylene. The unreacted ethylene is not recovered.
The masses of the solutes in each of the solutions are the same. When the solutions are added together, a blood-red precipitate forms. After the reaction has gone to completion, you dry the solid and find that it has a mass of 331.8 g.
Acetone of at least 95 mol% purity is wanted, and the aqueous effluent must not contain more than 1 mol% acetone. The feed will be a saturated liquid. Estimate the number of ideal stages required.
If this alternator is to generate 60-Hz voltages, find the new synchronous speed, and calculate the new terminal voltage for the same field current.
A plant is producing 10,000 metric tons per year (10 kt/y or 10 kMTA) of a product. The overall yield is 70 wt% (0.7 kg of product per kg raw material). The raw material costs $500/metric ton, and the product sells for $900/metric ton. A process m..
Determine whether a linear correlation of y with x accounts for all but the error variation in y from the following replicate values of y at different levels of x.
A loaded semi-truck consumes about 10 US gallons of diesel per hour (assuming an average speed of 60 mph) and is driven about 16 hours per day, every day of the year. The density of diesel id 0.85 kg/liter. If 1 barrel of crude oil produces 10..
For a Thermo-Finnigan LTQ-FT running Xcalibur 2.0.1 how can you automate 10 MS3 experiments where only the activation time is changed?
It is known that carbon from a living organism has a decay rate of 15decays=min g and that 14C has a half-life of 5730 years = 3:01 109 min. Find the age of the skeleton.
For a coil current I (dc), derive an expression for the force on the plunger.
Draw the graph carefully. Please use one graph per country and show both the autarkyand the free trade equilibrium on each graph.
Should the second analysis be discarded based on a 0.95 probability level?
For the following cases: How much energy is lost every day when the steam temperature is maintained at 200oC, and the surrounding average air temperature is 20.0oC, and the surroundings average air temperature is 20.0oC? Neglect losses though the end..
