Draw the structure of the product(s) of the reaction between (R)-3-methylhexan-2-one and phenylmagnesium bromide, followed by acidification. Use wedge and dash bonds to indicate stereochemistry. If more than one stereoisomer is formed, draw them all.
When a dilute solution of a weak base (Ka- 3.5*10^-9) is titrated with a 0.100 M solution of HCl at 25 C, the equilibrium constant for the titration reaction has this value:
The net charge of a polypeptide at a particular pH can be determined by considering the pK value for each ionizable group in the protein
What would happen if you accidentally used 6M HCl aqueous solution instead of saturated Na2CO3 aqueous solution when extracting caffeine from tea bags.
The heat capacity of the calorimeter was 15.7J/K. The final temperature in the calorimeter was 32.4 degree C. What is the specific heat capacity of the mineral?
2NH4NO3(s) delta--->2N2(g)+4H2O(g)+O2(g): a) How many liters of water vapor are produced when 25.8 g of NH4NO3 decomposes? b) How many grams of NH4NO3 are needed to produce 10.0 L of oxygen
which effect on atomic size is more significant, the nuclear charge (p+) or the energy level that the eleectrons are filling explain why.
