One of the classical methods for the determination of the manganese content in steel is to convert all the manganese to the deeply colored permanganate ion and then to measure the absorption of light. The steel is dissolved in nitric acid, producing the manganese(II) ion and nitrogen dioxide gas. This solution is then reacted with an acidic solution containing periodate ion; the products are the permanganate and iodate ions. Write balanced chemical equations for both these steps.
design a heat exchanger for the following dutyreduced crude oil leaving a distillation unit with a flow rate of 3166.04
Design a sieve plate column to perform this separation, for a feed rate of 10,000 kg/hour. Treat the feed as a binary mixture of ethanol and water. Take the feed temperature as 20 °C. The column will operate at 1 atmosphere.
Calculate the chemical potential of methanol in solution with acetic acid at xMeOH = 0.8, 80 °C, 0.4 bar. The reference state is the pure liquid at 80 °C, 0.4 bar.
Take the natural gas to be an ideal-gas mixture with temperature-dependent heat capacities for each component given in Perry's Handbook. Is the ideal-gas assumption reasonable?

estimate the heat transfer rate across the slab and the temperature recorded by a thermocouple embedded 3cm from phaseA (assume conductivity of metal sheet is 55w/mdegree.
Describe the facilities and equipment plan and technology plan? Also prepare an organizational chart that depicts the company's structure.
Does this distribution fit a normal distribution curve?
A liquid containing 60 mol% toluene and 40 mol% benzene is continuously distilled in a single-equilibrium-stage unit at atmospheric pressure. What percent of benzene in the feed leaves in the vapor if 90% of the toluene entering in the feed leaves..
The scaling factor k must be such that the total probability is one. Therefore, we have k = 1/36. The table shows one instance where x + y >5, which is x = 3, y = 3. The probability is p = 9/36 = 1/4.
In the storage of flammable liquids, if the composition of the vapor-air mixture above the liquid surface falls within the flammability limits, a floating roof tank would need to used or the tank blanketed with inert gas. Check if the vapor compos..
