Which of the following intermolecular forces plays a pivotal role in the unique properties of water? a. dipole-dipole force. b. ion-dipole force. c. hydrogen bonding. d. dispersion force. c. hydrogen bonding

Correct answer choice is :

C) Hydrogen bonding

Explanation:

A hydrogen bond is a partly electrostatic tendency in a hydrogen which is bound to a more electronegative atom such as nitrogen, oxygen, or fluorine, and another nearby atom having a lone pair of electrons. Hydrogen bonds can happen within molecules or within various parts of a single molecule. Depending on the nature of the giver and acceptor atoms which compose the bond, their geometry, and atmosphere, the energy of a hydrogen bond can differ between 1 and 40 kcal/mol.

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow
