The measured dipole for a binary molecule is 0.53 D with a bond length of 219 pm. What is the separated charge, in coloumbs?(ID=3.34x10^-30).
If a pure R isomer has a specific rotation of -134.0°, and a sample contains 60.0% of the R isomer and 40.0% of its enantiomer, what is the observed specific rotation of the mixture
calculate the number of moles of He gas is present in a 1500ml balloon at a pressure of 640 torr and temperature of 25 degrees Celsius?
high spin whereas octahedral complexes can be either high or low spin, depending on the metal and/or ligand. What is the most likely explanation of this experimental result?
1) Prions are smaller than viruses, which are affected by radiation. 2) Prions do not contain genetic information, which is affected by ionizing radiation.
An important industrial for synthesizing the ammonia used in agricultural fertilizers involves the combination of N2 and H2 N2 (g) + 3H2 (g) 2NH3 (g) (Kc =4.29 *10^8 at 52 degrees C)
The average mass of a carbon atom is 12.011. Assuming you were able to pick up only one carbon atom, the chances that you would choose a carbon atom with a mass of 12.011 is:
As space exploration increases, means of communication between humans and other planets are being developed
a quanity of gas exerts a pressure of 98.6 kpa at a tempature of 22 degrees celcius. If the volume remains unchanged, what pressure will it exert at -8 degrees celcius
What fraction of the spherical atomic volume is occupied by the nucleus? What fraction of this atom's mass is contributed by its nucleus?
Calculate the molar kinetic energy (in joules per mole) of a sample of Ne(g) at (a) 25.00 degree C and (b) 26.00 degree C
In trans-1,2-dibenzoylethylene, even though the conjugated C=O group frequency coincides directly with the expected C=C stretching fequency, we would not have expected to observe the late stretching mode in the infrared spectum. Why
Do the same to show the formation of both elimination products from 2-bromo-2methylbutane (page 208 lists the two products as 2-methyl-1-butene and 2-methyl-2-butene.)
