Write the reaction showing autoprotolysis taking place in liquid ammonia. Using this reaction, provide the definition of acids and bases in liquid ammonia.
Explain what is the difference between the syn and anti additions in terms of the nature of the product and its optical activity
based on the ionization energies of the alkali metals which alkalimetal would you expect to undergo the least
For a process at 451 K and constant pressure, S surr is -326 J K-1. Calculate the quantity of heat (in kJ) absorbed by the system.
Solid iron(III) oxide reacts with solid aluminum to produce solid iron and solid aluminum oxide. If 50.0 grams of iron(III) oxide were mixed with 50.0 grams of aluminum, what maximum mass of iron metal could be produced?
laser light scattering on a dilute solution of lysozyme is carried out. The light intensity autocorrelation function decays exponentially with lifetime τC= 16.1 *10^-3 sec. An argon ion laser is used at wavelength of 488 nm and the scattering angl..
