As conjugated dyes get longer, two effects compete. The Equation, ?= 8mcL^2/h(2ni+1) indicates that as ni increases, the absorption wavelength should decrease, but as L increases, the absorption wavelength should increase. Which one wins and why?
Determine the point group of each of the three possible geometries of the hypothetical Be3+ on, ten draw the molecular orbitals for each geometry,
Place palmitic acid at the middle position. Cis/trans isometry is graded -it may help to draw hydrogen atoms associated with the carbon atoms of the double bond.
EDTA solution to reach the end point in a titration. What mass (in milligrams) of CaCO3 (FW = 100.09 g/mol) will react with 1.85 mL of the EDTA solution?
A beaker with 130 mL of an acetic acid buffer with a pH of 5.00 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M.
A 0.4780-g sample of impure Ca(OH)2 is dissolved in enough water to make 57.00 mL of solution. 20.00 mL of the resulting solution is then titrated with 0.1140-M HCl.
What mass of sucrose should be combined with 479 of water to make a solution with an osmotic pressure of 8.00 at 315 ? (Assume the density of the solution to be equal to the density of the solvent.)
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?
Express the hamiltonian operator for the internal motion of Li atom and the proper expression for the approximate
Solutions of sodium carbonate and silver nitrate react to form solid silver carbonate and a solution of sodium nitrate. A solution containing 3.60g of sodium carbonate is mixed with one containing 5.14 of silver nitrate.
The photochemical reaction of 2,4-dimethylpentane with molecular chlorine affords a mixture of monochlorinated alkyl halides. Draw teh structures of these products and predict the molar ratio when the reaction is run at 25C
A buffer was prepared by adding 2.4 g of ammonium nitrate to 100.0 mL of 0.30 M ammonia (Kb = 1.8 × 10-5). To this solution was then added 10.0 mL of 0.30 M sodium hydroxide
The Ksp value for the dissociation of barium nitrate is 0.00464. The molar solubility of barium nitrate is consequently 0.105 M. If the concentration of the barium ion in a saturated solution of barium nitrate was raised to 0.178 M (this is not th..
