Question

CAN I PLEASE GET SOME HELP?

You accidentally spilled an unknown liquid on a lab bench. It spreads out across the lab bench and quickly evaporates. What can you infer about the structure of the molecules? Explain your reasoning.

Answer 1

See note under explanation

Step-by-step explanation:

That the particles have mostly non-polar structures or, have a very low degree of electronegativity (i.e. very low or no attractive interactions) so that particle - particle interaction favors the gas phase when not in an equilibrium based environment. That is, a closed container of liquid were liquid phase is in equilibrium with gas phase. However, when not in a closed container; i.e., spilled, particles evaporate rapidly moving into the gas phase from liquid phase.

Hope this helps. :-)
