What is the molecular formula of a compound with the empirical formula C2H3N if its molar mass is about 123.15 g/mole? For your answer simply put subscripts directly after the element's symbol. You do not need to put anything for a subscript of '1'. For example, if your answer is supposed to be 'C2H2N2' then you would input 'C2H2N2'. Your answer should be written Carbon first, Hydrogen second, and Nitrogen third.

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .
