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.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
