26 xeof4 has one of the more interesting structures among noble gas compounds. on the basis of its symmetry, a. obtain a representation based on all the motions of the atoms in xeof4. b. reduce this representation to its component irreducible representations. c. classify these representations, indicating which are for translational, rotational, and vibrational motion. d. determine the irreducible representation matching the xenon–oxygen stretching vibration. is this vibration ir active?

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
