A sample of propane (C3H8) is placed in a closed vessel together with an amount of O2 that is 3 times the amount needed to completely oxidize the propane to CO2 and H2O at constant temperature. Calculate the mole fraction of each component in the resulting mixture after oxidation assuming that the H2O is present as a gas, and the partial pressure of each gas assuming that the total pressure inside the vessel following the reaction is 5 atm. Assume all gases are ideal.
it takes 261 kj/mol to eject electrons from a certain metal surface. what is the longest wavelenght of light(nm) that can be use to eject electrons from the surface of this metal via the photoelectric effect?
the product for the following reaction between THF and excess HI, and provided a detailed step-bystep mechanism for its formation, using the curved arrow formalism
What is the value of the rate constant for the reaction? How much time will take the consentration to drop to one tenth of its initial value?
Is the reaction spontaneous?
Why was acetone added to the reaction mixture only after we briefly mixed the catalyst and the behzaldehyde? 3. Why doesn't the dibenzalacetone product react (via the aldol condensation pathway) with the excess benzaldehyde in the reaction mixture..
The partial pressures of gas A and gas B, respectively, are 0.263 atm and 0.676 atm. If 0.160 mol a third gas is added with no change in volume or temperature, what will the total pressure become?
the slopes corresponding to standard Beer's Law plots were as follows: ?IA = 0.072 ?IB = 0.306 ?IIA = 0.760 ?IIB = 0.036 Using this data, calculate the ratio between the relative concentrations of MR- and HMR in this solution.
