Suppose you have a 0.0170 L sample of H24 24 2424224
SOof unknown concentration. If this amount of HSOis used to exactly titrate 0.0450 L of NaOH that has a concentration of 0.235 M, what is the molarity of the HSO? HINT: HSO (aq) + 2NaOH (aq) → 2HO (l) + NaSO(aq

: K for water = 0.512 C*kg solvent/mol solute
—You must show all work in detail to receive credit.—
(PART 2) Place the above solutions in order of boiling point from lowest to highest.
From models of SF4, BrF3, and XeF4, deduce whether different atom
arrangements, called geometrical isomers, are possible, and, if so, sketch them below. Indicate the preferred geometry for each case and suggest a reason for your choice. Indicate which structures have dipole moments, and show their direction.
Calculate the formal charges of all atoms in NH3, NO2-, and NO3-.
