At a particular temperature the first-order gas-phase reaction N2O5 ? 2NO2 + (1/2)O2 has a half-life for the disappearance of dinitrogen pentoxide of 5130 s. Suppose 0.450 atm of N2O5 is introducted into an evacuated 2.00 L flask. What will be the total gas pressure inside the flask after 3.00 hours
Treatment of A with zinc amalgam and HCl affords an optically active, dextrorotatory hydrocarbon C. Identify compounds A, B, and C, including stereochemical configurations. Be sure to explicitly draw H and both wedge/dash bonds at any configuratio..
How would you prepare 2-chloro-2-methyloctane in a lab begining with 2-methyl-2-octene and hydrochloric acid? It is reacted over heat with Ch2Cl2.
what are possible reasons for the differences observed in conductivity for H3PO4 and H3BO3? Explain it please. B) Write out the dissociation steps for H3PO4 and H3BO3.
It takes 54.0 J to raise the temperature of an 8.00 g piece of unknown metal from 13.0rm ^circ C to 24.5^circ{C}. What is the specific heat for the metal?
the average soil organic carbon content = 0.01%. assume that soil organic carbon is the primary sorbent and that degredation and dispersion are negligible.
Explain solubility rules used to predict precipitation reactions. Predict if precipitation occurs in the mixing reactions of the following aqueous solutions
If 110 {rm mg} of fluorine-18 is shipped at 8:00 A.M., how many milligrams of the radioisotope are still active if the sample arrives at the radiology laboratory at 1:30 P.M.
When some ionic compounds dissolve, not all of their bonds dissociate. What kind of conductivity would you expect such a solution to have?
How many grams of precipitate are formed if 0.27 grams of barium nitrate is mixed with 0.2 L of 0.8 M potassium carbonate?
Label and identify ALL functional groups. Label the chiral carbons (*), label the priorities (1,2,3,4) of the four "things" connected to the chiral carbon, draw the arrow or rotation and identify as R or S.
