Question
Step 1: Solvent molecules are separated from each other to make room for the solute. Step 2: Solute molecules are separated so they fit into spaces in the solvent. Step 3: Separated solute and solvent molecules are brought together filling in the spaces. A 20.00 ml sample of a Ba(OH)2 solution is titrated with 0.245 M HCI. If 27.15 mL of HCI is required, what is the molarity of the Ba(OH)2 solution? A) 0.166 M B) 0.180 M (C) 0.333 M (D) 0.666 What is the mass percent of oxygen in Al2(SO4)3 18H2O? (molar mass is 666.43 g/mole) (A) 9.60 % (B) 28.8 % (C) 43.2 % (D) 72.0 %

Pb(CIO4)2 + 2 KCI → PbCl2 + 2 KCIO4 A chemist mixes dilute solutions of lead (II) perchlorate and potassium chloride to precipitate lead (II) chloride (Ksp = 1.7 x 10-5). Within a factor of 10, what is the approximate molar solubility of PBCI2 in a solution of 0.20 M CI1 ions? 1.6 x 102 M (A) (B) (C) (D) 1.7 x 105 M 5.0 x 103 M 4.0 x 10-4 M Ethanoic acid (CH3COOH) has a much lower vapor pressure than ethanol (CH3CH2OH). What is the most reasonable explanation? (A) The polarizability of two oxygen atoms increases the London forces of attraction in ethanoic acid compared with ethanol. (B) Hydrogen bonding in ethanoic acid is the strongest attractive force and is mainly responsible for the observed data. (C) Both ethanol and ethanoic acid have an - OH, so the difference is the dipole of the second oxygen that increases the attractive forces. (D) Ethanol has an – OH group and can hydrogen bond; therefore, the London forces must cause the effect.
