Inice, the crystalline lattice is dominated by a regular array of hydrogen bonds which space the water molecules farther apart than they are in liquid water. This accounts for water's decrease in density upon freezing. In other words, the presence of hydrogen bonds enables ice to float, becau...

How many hydrogen bonds can a water molecule form? Can amines hydrogen bond? Water is formed by which type of bond? What type of bond is formed in a covalent compound? What is an H-bond and what are the conditions for forming an H-bond?
The high number of hydrogen bonds that exist within liquid water cause the water molecules to be farther apart than the molecules may be in other liquids (the bonds take up space themselves). In liquid water, the bonds are constantly being formed, broken, and reformed, so that the water ca...
nylon:Hydrogen bonds are found between the repeating units of the polymer. hydrofluoricacid(HF): Hydrofluoric acid forms what is called a symmetric hydrogen bond, which is stronger than the regular hydrogen bond. This type of bond also forms in formic acid. ...
Why is hydrogen important as a future clean energy source? A fuel is a chemical that can be ‘burnt’ to provide useful energy. Burning normally means that chemical bonds between the elements in the fuel are broken and the elements chemically combine with oxygen (often from the air). ...
Liu GL, Yao KD. What causes the unfrozen water in polymers: hydrogen bonds between water and polymer chains? Polymer. 2001;42:3943-7.W. G. Liu, K. D. Yao, What causes the unfrozen water in polymers: Hydrogen bonds between water and polymer chains? Polymer 42, 3943-3947 (2001)....
There are different types of bonds based on electronegativity. One bond type is known as polar covalent. Which choice below has this bond type? A. hydrogen gas B. NaCl C. water D. all of the compounds E. none of the compoundsDescribe the follo...
. When ice is frozen, the water molecules extend themselves as far as they possibly can but are held firmly together by hydrogen bonds. Water expands when it is frozen, but is still composed of the same number of molecules, thus decreasing its density and allowing it to float in water....
hydrogen bonding is quite dynamic, meaning thathydrogen bonds are constantly changing. In water, that means that they are constantly breaking and forming between the different water molecules. The pictures above are just snapshots in time, because the process of forming and breaking bonds happens way...
