When water evaporates do the covalent bonds between O atoms and H atoms break or do the hydrogen bonds break and why?
When water evaporates, it is the hydrogen bonds between water molecules that break, not the covalent bonds within each water molecule. The hydrogen bonds are weaker intermolecular forces that hold water molecules together. Breaking these bonds allows the water molecules to escape as vapor.
If all the hydrogen bonds in a DNA molecule were to break what would happen?
If all the hydrogen bonds in a DNA molecule were to break, the two strands of the DNA molecule would separate. This process is known as denaturation. The DNA molecule would no longer be able to function properly for processes such as replication or transcription.
What are the three diferentes types of side bonds?
The three different types of side bonds found in hair are hydrogen bonds, salt bonds, and disulfide bonds. Hydrogen bonds are weak and can be temporarily broken by water or heat, while salt bonds are somewhat stronger and can be altered by changes in pH. Disulfide bonds are the strongest type of side bond and require a chemical process like perming or relaxing to break.
Which bond is stronger an ionic bond or a hydrogen bond?
Ionic bonds are far stronger than hydrogen bonds. Ice is held together by hydrogen bonds, and table salt, which is sodium chloride (NaCl), is held together by ionic bonds. You can hammer on ice and break the hydrogen bonds holding it together with relative ease. But you can hammer all day on salt, turn it to a white powder, and not break the sodium-chlorine bonds (those ionic bonds) in any molecules of salt by doing so.
How are temperature and hydrogen bonds related?
Hydrogen bonds are weaker bonds that form between hydrogen atoms and electronegative atoms like oxygen or nitrogen. Temperature affects the strength of hydrogen bonds because it influences the movement of molecules. At higher temperatures, molecules have more kinetic energy and move faster, which can break hydrogen bonds.
When hydrogen bonds break what happens to energy?
When hydrogen bonds break, energy is absorbed from the surroundings to break the bonds. This results in a cooling effect as energy is used to separate the molecules. Conversely, when hydrogen bonds form, energy is released into the surroundings, leading to a warming effect.

How is a DNA molecule held together and separated by?
A DNA molecule is held together by its hydrogen bonds. The bonds are in between the bases of the molecule, for example cytosine and guanine. Because hydrogen bonds are weak, they are able to break apart easily and split when the molecule needs to be separated to bond with another DNA molecule for reproduction.
What happens to chemical bonds in a molecule during a chemical reaction?
The existing chemical bonds break and new bonds are created to give products.
What does the cell get when it breaks the bonds of the glucose molecule?
when you break the bonds of the glucose molecule you get energy.
The process of breaking apart two bonds with water is called?
When certain molecular crystals are added to water, they are able to dissolve and break down into their original molecules, if they are affected by the interatomic hydrogen bonds that water induces. A simple answer: dissolving.
What types of bonds will break when frozen water is heated and becomes liquid?
Of course. The reason for water's solid structure when frozen is due only to hydrogen bonds, which form a type of crystal lattice structure. When heat is applied, these bonds break, and water becomes liquid once again. then you crap yourself.
Can hydrogen oxygen in the water molecule break by applying the resonance high frequency?
No, the hydrogen-oxygen bond in a water molecule cannot break by applying resonance high frequency. Resonance involves the oscillation of electrons within molecules or chemical bonds but does not have enough energy to break covalent bonds like the one between hydrogen and oxygen atoms in water.
The bond energy of hydrogen molecule?
The bond energy of a hydrogen molecule is 412 KJ/mol, or 4.27 eV. A Google search for Hydrogen molecule 432 produces a list of online books that report this value Even better, Hydrogen molecule 1312 links to the online edition of Inorganic Chemistry, by James E. House, page 71, where the concept of bond energy is clearly defined and it is shown how the number 412 is calculated.

How do intra-molecular hydrogen bonds affect the molecule in its gaseous phase?
In general, the way the hydrogen bonds affect something (like water) in its gaseous phase is that they still want to "hang on a bit" and "connect" the molecules. But they can't because the molecules have too much kinetic energy. Remember that the electrostatic attraction that is the basis for hydrogen bonds didn't just "disappear" when the molecule gained enough energy to escape its liquid associates and become a gas. It's still there and plays a minor role in the behavior of the molecule. There is something else that is important when something like water is a gas in air (because the water molecules have enough energy). A water molecule may form a bond and combine with another molecule briefly, and then break away. In fact, molecules of water may be (will be) forming hydrogen bonds with other moledules and then breaking away all the time. The higher the energy of the system in which the molecules are operating, the less frequently a pair of water molecules will "hook up" and the less time they'll stay together. But the "hook ups" will still happen to a degree. In liquid water, the hydrogen bonds make and break all the time, but the "low energy" in a container of liquid water allows the hydrogen bonds to "call the shots" because the molecules don't have the energy to break away as easily.
