Based on reactivity, which of the following elements can replace aluminum (al) in a compound during a single replacement reaction?

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.

Which of these is a physical property

Light waves can move through , but they travel fastest when they move through a(n) .
