A drop of the NaOH titrant adheres to the side of the buret between the initial and final readings for the titration. As a result of the "clean glass" error, will the molar concentration of the NaOH solution be reported as too high or too low. Explain.
The normal freezing point of ammonia is -78 degrees celsius. Predict the signs of Delta H, Delta S, and Delta G for ammonia when it freezes at -80 degrees celsius and 1 atm: NH3 (l) ---> NH3 (s)
calculate the equilibrium concentration of HI when 0.500 M HI, 0.0200 M H2, and 0.0200 M I2 are placed in a sealed flask and allowed to reach equilibrium. Kc for this reaction is 50 at 445 ºC.
Draw (2R,3R)-2-bromo-3-phenylpentane in the conformation from which it is most likely to undergo E2 elimination to give 3-phenyl-2-pentene.
