  2. B is not true.
    C is not true.
    Look up colligative properties.

  4. You apparently have no concept of how the freezing point of a pure material such as water is affected by the solute. Out of four choices you guessed wrong on three so th answer obviously must be A. Also it is obvious you didn't look up anything about colligative properties. A non-volatile solute dissolved in a pure solvent (not just H2O) will lower the freezing point of that solvent. For water that is 1.86 degrees for a 1.0 molal solution of a non-electrolyte. For materials such as salt, NaCl (an electrolyte), it is twice that. While we're on colligative properties, that same solution will boil at a higher temperature. All of this is summed up by the following:
    When a non-volatile solute is dissolved in a volatile solvent, three things happen.
    1. The freezing point is lowered.
    2. The boiling point is raised.
    3. The vapor pressure is lowered.
    The extent to which these three things happen depends SOLELY upon the number of dissolved particles.

  6. This website is so rude! "Hun"?
    "Look it up." That's what he/she are doing. They are trying find help. So immature.

  7. How is "hun" rude? it's a term of endearment like what a mother would say to a child. This website isn't rude it's what people post that's rude. But Lily Gardener was not being rude, Sophia877.
