The production of cement results in significant GHG emissions. The emissions are caused by the decomposition of calcium carbonate (limestone) to calcium oxide (lime) and carbon dioxide. This process known as calcination, is carried out in kilns. Therefore, additional GHGs are emitted as a result of heating the kilns. A large cement manufacturer uses a mix of coal, natural gas, and biomass in its boiler. This mix produces the following amounts of GHGs per Million BTUs of energy: • 250 lbs CO2/MMBtu • 5 lbs CH4/MMBtu • 0.36 lbs N2O/MMBtu Process carbon emissions from the calcination process produce 925 lbs of carbon dioxide per metric ton of cement. In addition, the plant uses 1.7 Million BTUs of energy per metric ton of cement. If the plant produces 180,000 metric tons of cement annually, how many metric tons of CO2e does it emit?
A 0.2m3 rigid tank initially contains pure oxygen gas (02) at 20°C and 1000 kPa. The tank containing the oxygen is put on a scale to measure its mass. The initial mass is recorded as 110.4 kg. Nitrogen gas is injected isothermally into the tank until the scale reads 121.0 kg. The molar mass of oxygen is 32kg/kmol and the molar mass of nitrogen is 28 kg/kmol. Assuming that the gases behave ideally, answer the following questions: a) What is the mass of the empty tank? b) What is the composition of the final mixture on a mole basis? c) What is the final pressure of the tank? d) The critical temperature and pressure of oxygen are 154.6K and 49.8atm. Based on these properties, comment on the appropriateness of using the ideal gas law in part a)
A mixture of gaseous reactants is put in to a cylinder, where a chemical reaction turns them in to gaseous products. The cylinder has a piston that moves in or out as necessary to keep a constant pressure on the mixture of 1 atm. The cylinder is also submerged in a large insulated water bath. From previous experiments, this chemical reaction is known to absorb 243. kJ of energy. The temperature of the water bath is monitored, and it is determined from this data that 109.kJ of heat flows out of the system during the reaction. A.) is the reaction exothermic or endothermic? B.) Does the temperature of the water go up or down? C.) does the piston move in, out, or neither? D.) does the gas mixture do work, Or is work done on it? E.) how much work is done on (or by) the gas mixture?
For the equilibrium system: H2O(g) + CO(g) <--> H2(g) + CO2(g). Delta heat of rxn: -42 kJ/mol and Kc=0.62 at 1260 K.0.10 mol each of water, CO, and CO2 (all at 1260 K) are placed in a sealed 1.0-Liter thermally-insulated vessel, which is also at 1260 K. When the system comes to equilibrium, which is true?-The temp & mass of CO would increase.-The temp & mass of CO would decrease.-The temp would remain constant & the mass of CO would increase.-The temp would increase and the mass of CO would decrease.-The temp would decrease and the mass of CO would increase.
Hydrogen gas (H2) at 25°C, 1 atm enters an insulated reactor operating at steady state and reacts with 250% excess oxygen entering at 227°C, 1 atm. The products of combustion exit at 1 atm. Determine the temperature of the products, in K, if combustion is complete.
