Determine the number of phases, components, and the variance (degrees of freedom) for the following: (a) A solution made from water, MgCl2 and KBr. (b) A solid mixture containing powdered graphite and powdered diamond. (c) A gaseous mixture containing water and carbon dioxide that was produced from the combustion of a stoichiometric mixture of oxygen and propane gases. Assume the reaction went to completion and there are no residual amounts of propane nor oxygen present.
