Chemical bonds: solder, flux and solvent cements are what make pipe joints stand the test of time.Deerr, Allison
Atoms and molecules are small indeed. Until recently, catching even a glimpse an atom was impossible. It still is impossible to see a chemical bond. Despite that, we know quite a few chemical reactions and can predict how many more will turn out. But we could know ever so much more abou...
few endothermic reactions happen by themselves. The process usually takes an input of energy to start the reaction and to maintain it. Even reactions that are exothermic overall may need an input of energy at the start to break some of the bonds. ...
What are some examples of covalent molecule? What type of bond holds atoms together because of their charge? How are covalent bonds formed? How is a hydrogen bond different from a covalent bond? What is the relationship between electronegativity and the polarity of a chemical bond? How do a ...
A double bond is a type of chemicalbondin which twoelectronpairs are shared between twoatoms. This type of bond involves four bonding electrons between atoms, rather than the usual two bonding electrons involved in a single bond. Because of the large number of electrons, double bonds tend to...

Soap is not a natural substance, but it can be made by heating fats with alkali to break some chemical bonds that link fatty acids to glycerin. Soaps are just the alkali salts of the resulting fatty acids. Since alkalis are formed when wood burns and are found in the ashes of wood ...

Pending bonds exist at interfaces between solids too. One reason is that both solids can't match their atom spacing, so some atoms have no neighbour at the other material. There, charges can be stored since lone electrons are easier to add or remove. This happens naturally in MOS transistor...
