(111) A hypothetical element xylo(symbol Xy) forms four different compounds with another hypothetical elemnent phone(symbol Ph). Using the old nomenclature, write the empirical formula for each compound. (a) xylo monophonide (b) dixylo triphonide (c) dixylo tetraphonide (d) xylo diphonide   (112) Using the formulas from question 111, dtermine the oxidation values for Xy and Ph and rename the compounds according to the Stock System. (Hint: First, use the empirical formula for dixylo triphonide to determine the oxidation number of Ph. The oxidation number for Ph is the same for the other compounds.) (a) (b) (c) (d)
