In part C of this experiment, it is possible that some of the unknown solid did not dissolve in the solvent. If this happened, after all other parts of the experiment had been done correctly, what would be the effect on the freezing point with the unknown present? How would the calculated molar mass change for the unknown solid? Specifically state whether the molar mass of the unknown would be erroneously high or erroneously low.

Crust,mantle,core,earth

What are the choices?

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.
