When a chemical is dissolved in a liquid, the freezing temperature of that liquid is slightly lowered as a result. One example of this is that salt water freezes at a lower temperature than pure water. The following table shows the freezing temperatures of several liquids. Liquid Temperature Water 0.0°C Acetic acid (vinegar) 17.0°C Ethanol (alcohol) -114.7 Of the choices listed, a liquid with a freezing point of -1°C would most likely be made of A. something dissolved in water.
B. pure ethanol.
C. something dissolved in acetic acid.
D. something dissolved in ethanol.

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.
