How can you use a Haworth projection to distinguish between an alpha and beta anomer, and between the L and D forms. Please explain with an example.
Alkynes can be hydrated in the presence of acid and HgSO4, by electrophilic addition of a molecule of water to the triple bond.
If 21.0 mL of silver nitrate solution reacts with excess potassium chloride solution to yield 0.882 g of precipitate, what is the molarity of silver ion in the original solution
The student then titrates the oxalic acid solution with her sodium hydroxide solution. When the titration reaches the equivalence point, the student finds she has used 0.1265 L of sodium hydroxide solution. Calculate the molarity of the student's ..
If we have a solution that contains 0.022 M Calcium and 0.014 Magnesium and we have to use potassium hydroxide to selectively precipitate one of the ions, while leaving the other ion in the solution.
consider the reactionc2h5oh l 3o2 g --gt 2 co2 g 3 h2o l ?h -1.37 x 103 kjwhen a 24.8-g sample of ethyl alcohol
to a sample of alkaline earth metal carbonate mco3 0.250 g was added 30.0 ml hcl 0.250 ml. carbon dioxide gas evolved
calculated using the energy level equation. A Li2+ ion emitted a photon with a wavelength of 11.4 nm to reach an energy level with n=1. What was the value of n for its initial energy level?
Speculate on the structure of the crossed benzoin-like compound formed while 4-dimethylaminobenzaldehyde is condensed with 4-chlorobenzaldehyde. Explain what structure will be formed
what is the solubility of CaF2 in a solution that has a equilibrium concentration of .01M EDTA? Ksp (CaF2)= 3.9 x 10^-11, Kf(CaEDTA)=5x10^10
Calculate the expectation values for a particle in the state n = 5 moving in a one-dimensional box of length 2.48×10^(?10)m If someone can just help me out with the set up of the problem thatd be helpful.
Draw an energy level diagram for a nonrelativistic particle confined inside a three-dimensional cube-shaped box, showing all states with energies below 15· (h2/8mL2). Be sure to show each linearly independent state separately, to indicate the dege..
