What type of intermolecular force causes the dissolution of kf in water?

Ion-Dipole Force

Explanation: An ion-dipole force is an attractive force that results from the electrostatic attraction between an ion and a neutral molecule that has a dipole. Most commonly found in solutions.

Ion Dipol

Explanation:

KF is a composition of potassium fluoride. potassium fluoride (KF) is an ionic compound in which K has positive ions and F has negative ions.

Water has the formula H2O. H2O has ends that have opposite charge. In the molecule, the dipole arranges itself so that the positively charged side will be close to the negative side. Then a very strong dipole pull occurs between molecules if they have hydrogen atoms bound to Nitrogen, Oxygen, or Fluorine. The positive end of the dipole can get closer to the other side of the negative dipole of the molecule, so that the two are close together and there is a very strong pulling force called a hydrogen bond. Strength of hydrogen bonds reaches 5-10% than covalent bonds.

hi,

the answer is third world countries, take for instance china, they restricted each family with only one child,

hope this !

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
