The empirical formula of both of the compounds is CH2 because the smallest whole number ratio of carbon to hydrogen is carbon. A) 3 B) 1 C) 12 D)4 please help !

In which phase(s) do the molecules take the shape of the container?

If a molecule with a molecular formula of c13h18 is treated with an excess of h2 in the presence of finally divided pt metal under conditions required for maximum hydrogenation of the molecule to give a molecule with a formula c13h24, how many rings are in the molecule?

Which is true of a liquid? it has a definite volume but not a definite mass.it has a definite mass but not a definite volume.it has a definite volume but not a definite shape.it has a definite shape but not a definite volume.
