Consider 1.00 mole of each of the following substances: 1) NaCl (sodium chloride) 2) CaCl2 (calcium chloride) 3) CH3OH (methanol) 4) Naphthalene (C10H8) Answer the following questions: A) Which one of the above substances would likely not change the freezing point of water at all? Explain. B) Which one of the above substances would likely lower the freezing point of water the most? Explain.
For each of the following pairs of substances, select the one expected to have the lower melting point: 1. H,O, H,S II. HCI, NaCl III. CH4, C3H Select one: a. H,O, HCI, C3Hg b. H,O, HCI, CHA O CH S, HCI, CHA d. H S, NaCl, CH, e. H,O, NaCl, C3H8
For each pair of substances, anticipate which one has a higher boiling point. HF has a .... than HCl . CCl4(l) has a .... than CH3Cl(g) . CH3OCH3 has a .... than CH3CH2CH3 . CH3OCH3 has a .... than CH3NHCH3 . H2S has a .... than H2Se
Use the References to access important values if needed for this question. List the following substances in order of increasing normal boiling points Tb, and explain your reasoning: He, HCI, HF, Nal Boiling point substance1-lowest Reason 4-highest Is an ionic compound: forces are stronger than forces between neutral molecules. Has hydrogen bonds: stronger than other dipole-dipole interactions Is polar: dipole-dipole forces are stronger than dispersion forces Is nonpolar: dispersion forces are weaker than dipole-dipole forces. HCI HF Nal Submit Answer...

24. Circle one word inside each set of parentheses in the following statement: (Solutions, colloids, suspensions) contain the smallest particle size and (solutions, colloids, suspensions) contain the largest particle size. Which statement about colligative properties is incorrect? A. Solutes will lower the freezing point and raise the boiling point of a solvent. B. Colligative properties depend only on the number of dissolved particles and not on their size or chemical properties. C. Colligative properties involve only charged particles in solution....
