Astudent has samples of two pure compounds, xclo3 and zclo3, which contain unknown alkali metals x and z. the student measures the mass of each sample and then strongly heats the samples to drive off all the oxygen, leaving solid residues of xcl and zcl. the student measures the mass of the solid residue from each sample. which of the following questions can be answered from the results of the experiment?
a. which has the greater molar mass, x or z?
b. which has the higher boiling point, x or z?
c. which has the higher melting point, xcl or zcl?
d. which has the greater density, xcl or zcl?
