what is the acidity of phenol?
Problem- A 0.682 g sample of aluminum metal was reacted with dilute sulfuric acid and the hydrogen evolved was collected over mercury at a barometric pressure of 737 torr and a temperature of 22 degrees C. What volume of hydrogen gas was collected
the gaseous mixture was removed and dissolved in more water. Sufficient silver (I) ion was added to precipitate the chloride ion completely as silver chloride. If 3.59 g AgCl was obtained, what is the value of Kc at 619ºC?
Calculate the energy (in eV/atom) for vacancy formation in some metal, M, given that the equilibrium number of vacancies at 404oC is 7.40E+23 m-3. The density and atomic weight for this metal are 15.9 g/cm3 and 65.20 g/mol, respectively.
Aniline is basic good electron pair donor. Acetanilide, nevertheless is neutral/not basic. Use structural formulae and resonance to explain this difference in basicities.
Find P given that 25 mL of toluene and 25 mL of an aqueous solution containing 0.000330 moles of an organic compound were shaken together and 31 % was extracted into the organic phase.
Problem- Consider an E2 reaction where a proton and a leaving group (LG) on adjacent carbon atoms are eliminated. The most favorable orientation for the proton and LG relative to each other is gauche, eclipsed, staggered, or anti. Why
Question- Nitrogen and oxygen do not react appreciably at room temperature, as illustrated by our atmosphere. But at high temperatures, the reaction below can proceed to a measurable extent.
