Answer is D.the volume of the unknown mass
Here is explain of your problem. First you have to write the equation: $Ca CO3\rightarrow CaO+CO2$ Then compute the mols of Ca CO3 Then compute the mols of CaO AND AT LAST THE MASS OF CaO
Because water molecules are polar and carbon dioxide molecules are nonpolar, A. water has a lower boiling point than carbon dioxide does. B. attractions between water molecules are weaker than attractions between carbon dioxide molecules. C. carbon dioxide cannot exist as a solid. D. water has a higher boiling point than carbon dioxide does.
Weegy: Carbon dioxide is a gas at room temperature, and water is a liquid at room temperature. [ Since 'boiling point' is the point at which a liquid becomes a gas, that would mean that the 'boiling point' of CO2 would have to be MUCH lower than water (or lower than room temperature for that matter).
