Lawrence is testing how quickly water with baking soda freezes. he adds water with baking soda to one ice tray and plain water to another ice tray. he places each tray in the freezer and records the time when each one starts to freeze. what is the treatment in this experiment?

a) water
b) baking soda
c) freezer
d) ice tray

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

dynamic equilibrium is the answer.
