When NH3 is prepared from 28g N2 and excess H2, the theoretical yield of NH3 is 34g. When this reaction is carried out in an experiment, only 30g is produced. What is the percentage yield?

Water ionizes by the equation h2o(l)⇌h+(aq)+oh−(aq) the extent of the reaction is small in pure water and dilute aqueous solutions. this reaction creates the following relationship between [h+] and [oh−]: kw=[h+][oh−] keep in mind that, like all equilibrium constants, the value of kw changes with temperature.

What is an example of a physical property?
