A 81 L sample of dry air cools from 145C to -22C while the pressure is maintained at 2.85 atm. What is the final volume?
then dried the flask and added some pieces of titanium to it. the stoppered flask plus the titanium weighed 64.763g. then filled the flask w/water, leaving the titanium pieces in the flask, and found a mass of 67.561g for the flask plus titanium a..
Consider a substance where the intermolecular forces hold the molecules in fixed rigid positions. What is the process called when enough heat has been added to the substance so that the molecules begin to flow
the compounds shown are possible acylation products from 124-trimethylbenzene pseudocumene. explain the only way you
Given the concentration of organic carbon in a soil sample and the soils bulk density, be able to calculate the mass of organic carbon
At 0.967 atm, the height of mercury in a barometer is 0.735 m. If the mercury were replaced with water, what height of water (in meters) would be supported at this pressure.
1 tums tablet is 1.3g which has .5g of calcium carbonate, how many moles of calcium carbonate are in one tums tablet? From that value, calculate the number of moles of HCI that two TUMS tablers can neutralize
A student measures the conductivity of an Fe2(SO4)3 solution and determines it to be a strong electrolyte. The student incorrectly lists the species in solution as O-2, S-2, Fe+3. Give the correct list of species in the solution.
Calculates the molarity of a calcium carbonate standard solution that contains 0.2430 grams of calcium carbonate dissolved in a total of 250.0 mL
One way to measure ionization energies is ultraviolet photoelectron spectroscopy (UPS, or just PES), a technique based on the photoelectric effect. In PES, monochromatic light is directed onto a sample, causing electrons to be emitted.
When Adding H2so4 to form alkene from alcohol what is the solvent used? is it just heat. What about when forming alkene from alkyl halide and NaOMe is used to form Zaitsev is the solvent MeOH. and what should be used to form Hoffman with t-BuOKC
