19. which property of the water molecule causes two water molecules to be attracted to each other? a. polar bonds between h and o atomsb. ionic bonding between water moleculesc. hydrogen bonds between h atomsd. dionic bonding between o atoms

Hydrogen bonds between H atoms

Explanation:  Hydrogen Bonding is the kind of force of attraction which can only be present in the molecules having electronegative atom and the hydrogen atom attached to it.

Thus water molecules have both Oxygen atom as the electronegative atom and hydrogen attached to electronegative atom O.

Thus one H atom of one water molecule forms a hydrogen bond with the oxygen atom of another molecule.

Moreover, these hydrogen bonds are weaker than the standard covalent bond.

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.
