What does breaking hydrogen bonds do?

Breaking hydrogen bonds allows the water molecules to escape from the liquid by vaporization, either by boiling or by evaporation.

What is called the cohesive property of water?

This property due to the formation of hydrogen bonds between water molecules is the cause of the water molecules sticking.

What is the importance of hydrogen bonds?

allows water molecules to stick together creating cohesion

What allows water molecules to dissociate ionic bonds and or to form hydrogen bonds?

Water molecules can dissolve ionic compounds and form hydrogen bonds because of their high polarity and lone-pair electrons on the oxygen atom.

The hydrogen bonds among water molecules endow water with which property?

Also the hydrogen bonds between water molecules have an influence on water surface tension (high) and capillary forces.

What type of bonds hold separate water molecules together?

Hydrogen bonds. Water molecules H2O have covalent bonds holding the hydrogen atoms to the oxygen. Between water molecules there are hydrogen bonds.

Do water molecules form hydrogen bonds with methane molecules?

No, methane has no polar hydrogen atoms to create hydrogen bonds.

What property does water show when the molecules are attracted to each other?

Hydrogen Bonds (not actual bonds but strong inter-molecular forces)

What molecules can form hydrogen bonds?

Hydrogen bonds are formed within molecules. In chemistry, they are the strongest of the 3 types of bonds (London Dispersion, Dipole-Dipole, and Hydrogen Bonding). Molecules that have hydrogen bonds have to have bonds between hydrogen and nitrogen or hydrogen and oxygen or hydrogen and fluorine (N-H, O-H, or F-H).

What water molecules stick to other water molecules. This property is called?

Cohesion is a property of water molecules, in which they stick together due to the fact that they form hydrogen bonds with one another.

What distinguishes hydrogen bonds from covalent bonds?

Hydrogen bonds are betweem molecules and are weak forces.

Why can insects walk on surface tension?

The answer is pretty simple, and has to so with properties of water, mostly, not insects. Water molecules are polar molecules containing Oxygen and Hydrogen. This allows them to form hydrogen bonds when in close proximity to each-other (hydrogen bonds are a strong type of Inter-molecular force.) The molecules on the surface, however, have less water molecules near them, and so form stronger hydrogen bonds with nearby water molecules. Some insects, like the iconic water strider, have large feet to displace their weight over a large area, and thus avoid breaking the surface hydrogen bonds, which allows them to "walk on water."

Are there hydrogen bonds between cholesterol and phospholipid molecules?

Yes there are hydrogen bonds between cholesterol and phospholipid molecules. These bonds are better known as hydrogen-bonded water bridges.

Can water form hydrogen bonds form with itself?

Intermolecular bonds of water molecules are hydrogen bonds.

What type of bond holds two water molecules together?

Hydrogen Bonds hold water molecules together.

What is a unique property of water Describe the property and explain the chemical or physical reason that causes water to have the property?

Hydrogen bonding causes water molecules to connect . The energy required to break multiple hydrogen bonds causes water to have a high heat of vaporization; that is, a large amount of energy is needed to convert liquid water, where the molecules are attracted through their hydrogen bonds, to water vapor, where they are not.

What takes away water molecules as molecules are combined?

The intermolecular bonds between water molecules are hydrogen bonds.

Where are the weak Hydrogen bonds located?

Hydrogen bonds occur between polar molecules such as water.

What bond bonds water molecules with other water molecules?

hydrogen bond bonds water molecules with other water molecules.

Are water molecules cohesive?

Water molecules are very cohesive due to the relative positive charge of their hydrogen atoms compared to their oxygen atoms, this allows them to form strong hydrogen bonds in a tetrahedral configuration.
