Suppose that you are closing a cabin in the north woods for the winter and you do not want the water in the toilet tank to freeze. You know that the temperature might get as low as 30. C, and you want to protect about 4.0 L water in the toilet tank from freezing. Calculate the volume of ethylene glycol (density = 1.113 g/mL; molar mass = 62.1 g/mol) you should add to the 4.0 L water.
Are each of the following things good or bad in a distillation? (a) The distillation stops at one point, and the temperature drops. (b) The material in the distilling flask boils violently and some sloshes up and into the condenser (c) You forget to run water through the condenser. (d) Distillate drops out of the condenser at the rate of about one drop per second.
A mixture of ethylene glycol (C2H6O2) and water is used as an antifreeze in cars. However, it is not just to keep the radiator from freezing but also to keep it from boiling over when hot. If a mixture is made with 500.0 mL of ethylene glycol (density = 1.11g/mL) and 500.0 mL of water (density = 1.00g/mL) what will the boiling point be of the mixture? Assume that water is the solvent with a boiling point constant of kb =0.512

A chemistry student weighs out 72. g of an unknown solid compound X and adds it to 550. mL of distilled water at 19.° C .After 10 minutes of stirring, only some of the X has dissolved. The student drains off the solution, then washes, dries and weighs the X that did not dissolve. It weighs 64. g .
A certain liquid X has a normal freezing point of 7.10°C and a freezing point depression constant =Kf3.27·°C·kgmol−1. A solution is prepared by dissolving some ammonium chloride (NH4Cl) in 700.g of X. This solution freezes at 6.4°C. Calculate the mass of NH4Cl that was dissolved.

15.0 grams of table sugar (C12H22O11) is added to 200.0 mL of water. Assuming that environmental conditions are the same and that pure water boils at 100 C, at what temperature will the sugar solution boil (Kb of water 0.512 C kg mol-1)?
A student dissolves 12.4g of ammonium nitrate (NH4NO3) in 200.g of water in a well-insulated open cup. She then observes the temperature of the water fall from 21.0°C to 16.9°C over the course of 7 minutes. NH4NO3(s) → NH+4(aq) + NO−3(aq) You can make any reasonable assumptions about the physical properties of the solution. Be sure answers you calculate using measured data are rounded to 2 significant digits. Note for advanced students: it's possible the student did not do the experiment carefully, and the values you calculate may not be the same as the known and published values for this reaction. 1. Is this reaction exothermic, endothermic, or neither? 2.If you said the reaction was exothermic or endothermic, calculate the amount of heat that was released or absorbed by the reaction in this case. = kJ 3.Calculate the reaction enthalpy ΔHrxn per mole of NH4NO3. = kJ/mol

A student mixes 20.0 g of a salt in 100.0 g of water at 20 °C and obtains a homogeneous solution. Which salt could this be and why? The solubility of KCI at 20 °C in 100.0 g of water is 10.0 g and the solubility of KNO3 at 20 °C in 100.0 g of water is 30.0 g. O KCI because it is saturated. O KCI because it is unsaturated. O KNO3 because it is saturated. O KNO3 because it is unsaturated.
