Balance using the half reaction method in an acidic solution: Cr(NCS)6<4->(aq) + Ce<4+> (aq) = Cr<3+>(aq) + Ce<3+> (aq) + NO3<->(aq) + CO2 (g) + SO4<2->(aq)
A small smelter converts galena (lead sulfide) into pure lead by heating the ore with an excess of oxygen. Sulfur dioxide is produced as an air pollutant, as a result of the reaction. To remove sulfur dioxide, the flue gas is passed through a slurry of lime (calcium oxide) to produce calcium sulfate. The smelter processes 120
See attached for full problem. The concentration of isobutene in the overhead product is 4.8 mole %, and the concentration of propane in the bottoms is 0.7 mole %. Calculate the moles of the various components in the overhead and bottoms per 100 moles of feed.
I am preparing for my chemistry exam and would appreciate a multiple choise quiz on the last chapter (i.e., ideal gas law, superconductivity, extensive properties, critical pressure, aerobic, etc.). Can you provide me with such a quiz with the answers provided. Thanks. Chemistry Quiz 2: Multiple Choice Questions 1) Eleme
A furnace burns a fuel oil, the composition of which can be represented as (CH2) n. It is planned to burn this fuel with 10 % excess air. Assuming complete combustion, calculate the composition of the flue gas on a dry basis. Please see attachment for the rest of the problem, including relevant diagrams.
The molecular weight of NaOH is 40. the molecular weight of a widely used buffer, HEPES, is 255. HEPES has a pK of 7.5 and is available in the acid form. how many grams og HEPES and NaOH are needed to produce one liter of a 0.5 molar solution of pH 7.5? of pH 7.0? of pH 8.5?
The sublimation pressures of solid chlorine are 352 Pa at -112 C and 35 Pa at -126.5 C. The vapor pressures of liquid Chlorine are 1590 Pa at -100 C and 7830 Pa at -80C. Calculate a)heat of vaporization b)heat of sublimation c)heat of fusio d)triple point I have already figured out the first three. The heat of sublimation
I have attached the graphs. I don't think the first one is useful, but i needed to plot the data and find the heat of vaporization. Hence, the reason for the second graph. I know that the slope is equal to the heat of vaporization/RT but I don't think I am getting the right answer.
