Industries use both open and closed systems. Which of the following is an exampleof a closed system?In the core of a nuclear reactor, water is heated by the nuclear reaction andchanges state to steam. The steam runs through pipes into a vat of fresh water,and the heat flows out of the steam into the fresh water. The steam condensesinto liquid water, and is pumped back into the core of the reactor.In a fractional distillation tower, crude oil is heated, and separated using theboiling points of the various components. The components are pumped todifferent sections of the plant to undergo further reactions.A boiler burns methane gas to heat water into steam, which is then pumped intoa reaction vessel where it reacts with organic feedstock to produce hexanol.Sulfur dioxide gas is reacted with oxygen gas to produce sulfur trioxide. This gasis then bubbled through water to produce sulfuric acid, which is pumped out ofthe reaction vessel. The relationship between heat transfer and change in temperature is given by Q =mcAt, where c is specific heat capacity. Under what conditions will c = Q?Om = 1 kgAT = 1 °COm = 1gAT = 10 °COm = 10 gAT = 10 °COm = 100 gAT = 10 °COm = 1gAT = 1 °C

Combustion of a 1.450 g sample of glucose yielded 23.01 KJ of heat. The calorimeter contained 1.900 kg of water; the bomb constant was 5378 J/degree C; the initial temperature of the bomb and the water was 22.45 degrees C. Predict the final temp of the system.
Methanol (CH3OH) is produced in the reaction of carbon dioxide and hydrogen via the reaction and process given below: CO2+3H2→CH3OH+H2O The fresh feed to the process contains hydrogen, carbon dioxide, and 0.400 mol% inerts (I). The reactor effluent passes through a condenser that removes essentially all of the methanol and water formed and none of the reactants or inerts. The unreacted reactants and inerts are recycled to the reactor. To avoid buildup of the inerts in the system, a purge stream is withdrawn from the recycle. 100 mol/h of feed to the reactor (not the fresh feed to the process) contains 29.5 mol% CO2, 68.0 mol% H2, and 2.50 mol% inerts. The single-pass conversion of hydrogen is 46.71%. What is the recycle-to-fresh feed ratio?
It is estimated that the net amount of carbon dioxide fixed by photosynthesis on the landmass of earth is 5.5*1016 g/yr of CO2. Assume that all this carbon is converted into glucose. Calculate the energy stored by photosynthesis on land per year, in KJ. Calculate the average rate of conversion of solar energy into plant energy in megawatts, MW. A large nuclear power plant produces about 103 MW. The energy of how many such nuclear power plants is equivalent to the solar energy conversion?
A chemical manufacturer produces ethylene oxide by burning ethylene gas with air in the presence of catalyst. If the conditions are carefully controlled, a substantial fraction of ethylene remains unconverted and some is completely oxidized to form carbon dioxide and water. Formation of carbon monoxide is negligible. After the gases leaving the absorber is as follows: 9.6%CO2, 3.0%O2 and 6.4% ethylene. Of the ethylene entering the reactor, what percentage is converted to ethylene oxide?
1 mol propane (C3H8) and stoichiometric amount of oxygen (O2) needed to combust propane was preheated to 400 K. After combustion, the products released are at 1500 K. The combustion products are H2O(l) and CO2(g). With 100% conversion was achieved, estimate the total heat released. Calculate the heat requirement for a reactor in combusting 1 mol of methane, CH4, with 25% excess air until the products reach a temperature of 1000 K. The reactants entered the reactor at 298.15 K and 100% conversion of methane is achieved. Assume air is approximately 21% O2 and 79% N2 and products are H2O(l) and CO2(g). Hint for both #1 and #2 – Combustion products at 298 K is CO2(g) and H2O(l). If the exiting temperature is above 373.15 K, H2O will leave as H2O(g). Therefore, you should account for the phase change of H2O(l) to H2O(g).

Subject: Physical Chemistry you are a food specialist in a company that specializes in refrigerated delicacies, and one of your brands requires being maintained at a temperature of 5°C. You determine average water activity (aw) at this temperature to be 0.2. One day, you are informed that the cooling systems on one of the delivery trucks carrying your company’s products malfunctioned while en route to its destination and it would not be fixed until the next delivery. The driver has informed you that the temperature in the delivery bay of the truck is averaging 55°C. You estimate a heat of sorption (Q) of 19 kJ/mol. Calculate the water activity of the brand at this elevated temperature and comment on it’s integrity. Should the delivery still push through? Or should the products be recalled and disposed
Chlorodifluoromethane (CHF2Cl) was widely used in the compression/cooling circuits of refrigeration or air-conditioning systems. Since the discovery that such compounds (HCFCs and CFC's) released into the atmosphere were a major cause of depletion of stratospheric ozone, newer refrigeration systems make use of certain hydrofluorocarbons (HFCs), which are degraded in the lower atmosphere, instead. Often, mixtures of such compounds are used. Suppose a sample of refrigerant gas consisting of a simple mixture of the gases pentafluoroethane (C2HF5) and difluorormethane (CH2F2) has a density of 3.06 g/L at 14 °C and 0.974 atm. Calculate the average molecular mass for this sample
