Essay upon Chemicals

Chemical substances

Alloy - A great alloy is a substance of melting two or even more elements together, by least one a metal. An Example: Examples of alloys include brass, bronze, 14k gold, and sterling silver.

covalent bond - A covalent bond can be described as chemical website link between two atoms in which electrons are shared together. � An illustration: There is covalent between the oxygen and each hydrogen in (H 2 O). Each of the bonds includes two electrons - 1 from a hydrogen atom and one from the air atom. Both atoms discuss the bad particals. �

Combination of si and air - The combination of si and o2 is much like carbon and hydrogen, si and o2 form many compounds. They are really commonly known as silicates An Example -- Beach fine sand is a good case in point for a combination of silicates.

Polymer - A large molecule made up of chains or perhaps rings of linked monomer units. Polymers usually have high melting and boiling points. The - Samples of Polymer can be PVC (poly vinyl chloride), polystyrene, and cellulose.

The liquid crystal – A the liquid having particular crystalline attribute, especially differntoptical properties in several directions once exposed to an electrical field. The liquid crystal is the actual image generator that you look at in the display.

Exothermic reaction –The term used to spell out a reaction or perhaps process that releases energy in the proper execution of heat. At times the term is applied to procedures that launch other forms of energy, such as electric power, sound, or perhaps light. An Example –The case would be combustable of wood.

Oxidation - Oxidation may be the loss of electrons during a reaction by a molecule,  atom or ion. An Example -- The case is straightener combines with oxygen to form iron oxide or corrosion. The straightener is said to acquire oxidized in rust.

Heating system natural gas - Natural gas is actually a fuel made from methane, combined with up to 20% of various other gasses such as ethane and other hydrocarbons. An example - Natural gas is a popular choice for heating system and...
