Two-hundred fifty pounds per hour of iron pyrites containing 90% FeS2 and 10% gangue are burned with 20% excess air based on conversion to SO3. The cinder discharged from the burner contains no sulfur. No conversion to SO3 occurs in the burner. The burner gas is passed through a converter which effects a 98% conversion of SO2 to SO3. The converter gas is passed to an absorber where all the SO3 is absorbed by 80% H2SO4 solution, which becomes 100% H2SO4 solution in the process. Establish a basis of one hundred pounds of iron pyrites Calculate: (a) the burner gas analysis, (b) the converter gas analysis, (c) pounds of 100% H2SO4 produced per 24-h day, if waste gas analyzes 0.19% SO2, 4.14% O2 and 95.67% N2

Whenever organic matter is decomposed under oxygen-free(anaerobic) conditions, methane is one of the products. Thus,enormous deposits of natural gas, which is almost entirely methane, serve as a major source of fuel for home and industry.(a) Known sources of natural gas can produce 5600 EJ of energy(1 EJ 10^18J). Current total global energy usage is 4.0X10^2 EJper year. Find the mass (in kg) of known sources of natural gas(Hrxnfor the combustion of CH₄=802 kJ/mol).(b) For how many years could these sources supply the world’stotal energy needs?(c) What volume (in ft³) of natural gas, measured at STP, isrequired to heat 1.00 qt of water from 25.0C to 100.0C (d of H₂O= 1.00 g/mL; d of CH₄ at STP =0.72 g/L)?(d) The fission of 1 mol of uranium (about 4X10^4 ft³) in a nu-clear reactor produces 2X10^13 J. What volume (in ft3) of naturalgas would produce the same amount of energy?
Coal-fired power plants emit CO2, which is one of the gases that is of concern with regard to global warming. A technique that power plants can adopt to keep most of the CO2 from entering the air is called CO2 capture and storage (CCS). If the incremental cost of the sequestration process is $0.019 per kilowatt-hour, what is the present worth of the extra cost over a 3-year period to a manufacturing plant that uses 100,000 kWh of power per month? The interest rate is 12% per year compounded quarterly.
A student is given a sample of a pink manganese (II) chloride hydrate. She weighs the sample in a dry, covered crucible and obtains a mass of 26.742g for the crucible, cover, and sample. Earlier she had found that the crucible and cover weighed 23.599g. She then heats the crucible to drive off the water of hydration, keeping the crucible at red heat for about 10 minutes with the cover slightly ajar. She then lets the crucible cool and finds it has a lower mass; the crucible, cover and contents then weigh 25.598g. In the process the sample was converted to off-white anhydrous MnCl2. a. What was the mass of the hydrate sample? _ghydrate b. What is the mass of the anhydrous MnCl2? _gMnCl2 c. How much water was driven off? _gH2O d. What is the percent by mass of water in the hydrate? water=massofwaterinsamplemassofhydrateinsample100 _massH2O e. How many grams of water would there be in 100.0g hydrate? How many moles? _gH2O; _molesH2O f. How many grams of MnCl2 are there in 100.0g hydrate? How many moles? What percentage of the hydrate is MnCl2? Convert the mass of MnCl2 to moles.
