Calculate the binding energy in kilojoules per mole of nucleons of P for the formation of 30P and 31P. The required masses (in g/mol) are 1^1H = 1.00783, 0^1n = 1.00867, 15^30P = 29.97832, and 15^31P = 30.97376.
explain what would happen to the cell during the process of osmosis and why?
How would you synthesize Acetophenone starting from an Alkene? Identify and draw the structure of the starting compound
We are investigating the keto-enol tautomerization of acetylacetone (pentane-2,4-dione) in an aqueous solutions at 25 degrees Celsius. The standard reaction Gibbs energy for the enol ketone tautomerization is -3.64 kJ/mol.
