Water can dissociate into OH- and H3O+, either through autodissociation or with the help of a stronger acid or base.
2H2O --> OH- + H3O+
When you run an electric current through water (electrolysis), you can break water apart further into elemental hydrogen and oxygen:
2H2O(l) --> 2H2 + O2
If we break a water molecule apart, we might get a hydronium ion (H+) and a hydroxide ion (OH-). Water dissociates all the time in its liquid form, and it does this:
H2O <=> H+ + OH-
Notice that the reaction is reversable, and some water molecules are "splitting" and "recombining" all the time in any container of water. This always happens, but the water is still water.
We also know that water can be broken down into its two constituent components. If we hydrolyze water by running an electric current through it, we'll collect hydrogen gas at one electrode, and oxygen gas at the other electrode. The equation looks like this:
2H2O + electrical energy => 2H2 + O2
Note the "2" in front of the water molecule (H2O) and in front of the hydrogen molecule (H2). We have to do that to balance the equation. Hydrogen and oxygen normally form what is called a diatomic molecule when they are in their elemental forms. Atoms of these elements will pair up with a like atom so they end up wandering around the atmosphere as a couple.
The liquid turns to a gas.
The liquid turns to a solid.
The liquid gains hydrogen atoms.
The liquid does not otherwise change.
it most likely releases the energy from it =D
When hydrogen bonds are broken in a particular compound, it would release the corresponding heat to the system.
you die
Heat. Intermolecular Hydrogen bonds (between two water molecules) are broken as water is heated to boil.The intramolecular hydrogen bonds (between H and O) stay intact
The term hydrogen bonding refers to a weak interaction between two molecules that contain an H atom bonded to a very electronegative atom, such O, N, and F. Hydrogen bonding does not occur within molecules, but rather between to molecules.Of course, the atoms of hydrogen can also form regular covalent or ionic bonds with other atoms to form molecules, and so these are in some sense hydrogen bonds, but that's not usually what people mean when they say the term "hydrogen bond."See the Web Links for more information about hydrogen bonding.
Hydrogen molecule doesn't have any hydrogen bonds. It only has one bond between the hydrogen atoms and that too is a covalent bond. A Hydrogen bond is a weak interaction between a hydrogen atom and a highly electronegative atom such as oxygen, Fluorine etc.It is not actual bonding.
The two strands of DNA that make up the double helix are connected by hydrogen bonds between the base pairs. For DNA to replicate, it must continuously zip and unzip the two strands. If those strands were held together by anything stronger than a hydrogen bond (say covalent bonds), it would require too much energy to unzip them and DNA would not be able to replicate. Were they to be held together by anything weaker dipole-dipole or dispersion forces), they probably would not stay together at all.
a hydrogen bond is a type of weak chemical bond. It is formed between the slightly positively charged hydrogen atom of one molecule and a slightly negative charged atom of another. A strong would be a covalent bond (it forms when atoms share electrons in order to become more stable)
a hydrogen bond is a weak interaction involving a hydrogen atom and fluorine, oxygen, or nitrogen atom...... there for it must form, not break because it is a weak interaction!
No, water does not have a weak hydrogen bond. In fact, the hydrogen bonds between water molecules are relatively strong compared to other types of intermolecular forces. These bonds are responsible for many of water's unique properties, such as high surface tension and specific heat capacity.
Hydrogen bonds are betweem molecules and are weak forces.
stong bonds are ionic bonds and covalent bonds and weak bonds are van der waals bonds and hydrogen bonds.
Weak bonds help to determine and stabilize the shapes of molecules. I onic bonds, hydrogen bonds, and van der Waals interactions are considered weak bonds.
Nothing. Hydrogen bonds are very strong. When ice is melted, only weak intermolecular forces of attraction that exist between H2O molecules will be broken.
Hydrogen bonds occur between polar molecules such as water.
Hydrogen Bonds
The hydrogen bonds between water molecules are weak bonds. They do not involve the sharing or transfer of electrons.
Hydrogen bonds are weak, but they are able to hold the backbones together. If covalent bonds held the templates together instead, the bonds would be even weaker and would likely break.
No, hydrogen bonds are weak in comparison to both ionic and covalent bonds.
Yes, H-bonds are weak bonds. The hydrogen bond is approximately 30 times weaker than a normal covalent bond.
