Chromium (cr) can combine with chlorine (cl2) to form chromium chloride (crcl3). which equation is a correction representation of this reaction?
2cr + 3cl2 --> crcl3.
cr + cl2 --> crcl3.
2cr + cl2 --> crcl3.
2cr + 3cl2 --> 2crcl3.

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.
