Question: Reaction of gaseous fluorine with compound x yields a single product y, whose mass percent composition is 61.7% F and 38.3%Cl.
(a) What is a probable molecular formula for product Y, and what is a probable molecular formula for X?
(b) Draw an electron-dot structure for Y, and predict the geometry around the central atom.
(c) Caculate DeltaH for the synthesis of Y using the following information:
2ClF (g) +O2(g) -> Cl2O(g) + OF2 (g) dH=+205.4 kj/mol
2ClF3(l) + 2O2 (g) -> Cl2O(g) + 3OF2 (g) dH=+532.8 kj/mol
(d) How much heat in kj is released or absored in the reaction of 25.0g of X with a stoichiometric amount of F2, assuming 87.5% yield for the reaction?
