Potassium chlorate is heated and decomposed as shown to produce potassium chloride and oxygen gas. The water in the collection flask is 25.0 ºC. The vapor pressure of water is 3.2 kPa at 25.0 ºC.

If the atmospheric pressure is 82.5 kPa, what is the partial pressure of the oxygen gas? kPa

the answer is c

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.
