Zinc (10 grams) + Hydrogen Chloride (5 grams) = zinc chloride (12 grams) + hydrogen gas (3 grams released) How was mass conserved?

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 type of reaction is illustrated? 2c12o5 = 2cl2 + 502
