Why is the answer A? Question 3A student has samples of two pure compounds, XC1O3 and ZC103, which contain unknown alkali metals X and Z. The student measures the mass of each sample and then strongly heats the samples todrive 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 ofthe experiment?Which has the greater molar mass, X or Z?(BWhich has the higher boiling point, X or Z?Which has the higher melting point, XCl or ZCl?(DWhich has the greater density, XCl or ZCl?
