Alkenes react in many addition reactions, which occur by opening up the double-bond.

Alkenes also react with halogens ( X < sub > 2 </ sub >) to form haloalkanes with two neighboring halogen atoms in a halogen addition reaction.

Alkenes are oxidized with a large number of oxidizing agents.

Alkenes and alkynes with more than one double or triple bond respectively are named with the appropriate numeric prefix preceding the-ene or-yne.

Alkenes with a hydroxyl group on both sides of the double bond are called enediols.

Alkenes can be oxidized with ozone to form alcohols, aldehydes or ketones, or carboxylic acids.

Alkenes are relatively stable compounds, but are more reactive than alkanes due to the presence of a carbon-carbon pi-bond.

Alkenes serve as a feedstock for the petrochemical industry because they can participate in a wide variety of reactions.

Alkenes can be ligands in metal complexes.

Alkenes undergo many important reactions that proceed via a photon-induced π to π * transition.

Alkenes are hydrocarbons that have one or more double bonds between carbon atoms.

and natural waters, in addition, often contain impurities such as calcium salts which can react with soils to make them more difficult to remove.

After blotting out most of the saline around the sections, a drop of Af was layered over each of the sections, allowed to react for 30 minutes, and then washed with PBS for 15 - 30 minutes.

Those who responded with an arm-elevation in the naive state did not change their reaction when told that there were some normal people who did not react in this fashion.

Some of those who did not initially react with an arm-elevation also associated their behavior in the situation with control factors -- an inability to relinquish control voluntarily.

All the alkali metals react with water, with the heavier alkali metals reacting more vigorously than the lighter ones.

The individual components react with each other after being mixed and show full adhesion only on curing.

Moisture curing adhesives cure when they react with moisture present on the substrate surface or in the air.

Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides, which react with the water molecules in the atmosphere to produce acids.

Acids in the rain react with the calcium compounds in the stones to create gypsum, which then flakes off.

The hydroxyl radical is particularly unstable and will react rapidly and non-specifically with most biological molecules.

In general, water-soluble antioxidants react with oxidants in the cell cytosol and the blood plasma, while lipid-soluble antioxidants protect cell membranes from lipid peroxidation.

Berkelium does not react rapidly with oxygen at room temperature, possibly due to the formation of a protective oxide layer surface.

From a sociological and demographic perspective, the Big Brother franchise allows the opportunity for analysis of how people react when forced into close confinement with people who lie outside their comfort zone, since they may hold different opinions or ideals from other contestants, or simply belong to a different group of people than a contestant normally interacts with.

A key claim made by Lord Lambert in his report had been that the channel was slower to react to breaking news compared with its main rival Sky News.

Banquo's ghost returns in a later scene, causing Macbeth to react with alarm during a public feast.

They are chemically resistant and require high temperature to react even with oxygen.

Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process regenerating the catalyst.

The open-chain form of a monosaccharide often coexists with a closed ring form where the aldehyde / ketone carbonyl group carbon ( C = O ) and hydroxyl group (- OH ) react forming a hemiacetal with a new C-O-C bridge.

The aldehyde or ketone group of a straight-chain monosaccharide will react reversibly with a hydroxyl group on a different carbon atom to form a hemiacetal or hemiketal, forming a heterocyclic ring with an oxygen bridge between two carbon atoms.

In 1805, English instructor and natural philosopher John Dalton used the concept of atoms to explain why elements always react in ratios of small whole numbers ( the law of multiple proportions ) and why certain gases dissolved better in water than others.

“ Clean ” or unpolluted rain has an acidic pH, but usually no lower than 5. 7, because carbon dioxide and water in the air react together to form carbonic acid, a weak acid.

Incomplete combustion will only occur when there is not enough oxygen to allow the fuel to react completely to produce carbon dioxide and water.

It can react with water to produce flammable hydrogen gas.

Thus the halides DbX < sub > 5 </ sub > should react with water to form DbOX < sub > 3 </ sub >.

Since acyl chlorides and acid anhydrides also react with water, anhydrous conditions are preferred.

The analogous acylations of amines to give amides are less sensitive because amines are stronger nucleophiles and react more rapidly than does water.

* Enthalpy of neutralization, defined as the enthalpy change observed in a constituent of a thermodynamic system, when one mole of water is produced when an acid and a base react.

Cells using water-based electrolytes are usually limited to cell potentials less than about 2. 5 volts, because the very powerful oxidizing and reducing agents which would be required to produce a higher cell potential tend to react with the water.

Once reaching the cathode, the ions are reunited with the electrons and the two react with a third chemical, usually oxygen, to create water or carbon dioxide.

On the cathode catalyst, oxygen molecules react with the electrons ( which have traveled through the external circuit ) and protons to form water — in this example, the only waste product, either liquid or vapor.

Indium does not react with water, but it is oxidized by stronger oxidizing agents, such as halogens or oxalic acid, to give indium ( III ) compounds.

When submerged in water, hydrogen bubbles will almost unnoticeably begin to form on the surface of the metal, though if powdered it will react much more rapidly.

Magnesium's ability to react with water can be harnessed to produce energy and run a magnesium-based engine.

Furthermore, water and formaldehyde can react via Butlerov's reaction to produce various sugars like ribose.

However, it is slow to react with water and air, because it forms a passive and protective oxide coating that protects it from further reaction.

When finely divided, it can react with cold water ; in air, uranium metal becomes coated with a dark layer of uranium oxide.

* As an oxide of hydrogen, water is formed when hydrogen or hydrogen-containing compounds burn or react with oxygen or oxygen-containing compounds.

Use of water in fire fighting should also take into account the hazards of a steam explosion, which may occur when water is used on very hot fires in confined spaces, and of a hydrogen explosion, when substances which react with water, such as certain metals or hot carbon such as coal, charcoal, coke graphite, decompose the water, producing water gas.
