An organic base (B) has a pKa of 6.950 and a distribution constant (KD), between water and ether, of 3.0. The organic base is extracted from 225 mL of a 0.175 M aqueous solution of B, that has been adjusted to a pH of 8.00, with 75.5 mL of ether. Only one extraction is performed. Calculate the concentration of the organic base (B) in the water phase after the extraction.

In this reaction n2o4(g)→2no2(g) what changes in color would you expect as pressure is increased at a constant temperature

Motivation cannot be developed with practice; a person either possesses it or they do not.

Many free radicals combine to form molecules that do not contain any unpaired electrons. the driving force for the radical–radical combination reaction is the formation of a new electron‑pair bond. consider the chemical equation. n(g)+no(g)⟶nno(g) n(g)+no(g)⟶nno(g) write lewis formulas for the reactant and product species in the chemical equation. include nonbonding electrons. n(g)n(g) select draw rings more erase select draw rings more erase select draw rings more erase n no(g)
