The chemical formula for an emerald is Be3Al2(SiO3)6. An emerald can be described as

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.

On a distance vs time graph the line of an object at rest is a
