Alkenes are hydrocarbons that contain a double bond between two carbon atoms. The general formula for an alkenes is CnH2n. Alkenes are important in the production of fuels, plastics, rubber, detergents, and pharmaceuticals. Example: Ethene (C2H4) is an alkene that has two carbon atoms and four hydrogen atoms. It is the simplest alkene and is …
IUPAC (International Union of Pure and Applied Chemistry) is the international body responsible for promoting the development of chemical nomenclature, terminology, standardized methods for measuring properties of chemicals, and safety standards for chemical products. IUPAC is responsible for publishing several chemical nomenclature and terminology standards, including the “Blue Book” which details the rules of naming …
Sulphuric acid is a strong oxidizing agent. It is a powerful dehydrating agent and can oxidize many metals and non-metals. It can also oxidize organic compounds, and can be used to create a variety of products.
When sulphuric acid is added to a salt solution, it will react with the salt to form sulphate and hydrogen ions. The reaction is as follows: H2SO4 + NaCl —> NaHSO4 + HCl This reaction is highly exothermic, meaning that it releases a large amount of heat energy. As a result, the solution may become …

Sulphuric acid is a very corrosive acid and it can cause severe burns and damage when it comes into contact with skin. It is also very hygroscopic, meaning that it easily absorbs moisture from its surroundings. As a result, it should never be left out in open air as it will quickly absorb moisture and …

Dehydrating sulphuric acid with heat is a common industrial process. It is done by heating it to temperatures above 300°C (572°F). This causes the sulphuric acid to rapidly lose its water content, drying it out and leaving behind a dense, anhydrous (water-free) form of the acid. The dehydrated acid is commonly used in the production …

The industrial preparation of sulphuric acid involves the oxidation of sulphur dioxide with oxygen in the presence of a catalyst. This process is known as the contact process. The reaction takes place in a series of steps. Sulphur dioxide is produced by burning sulphur or by the catalytic oxidation of sulphur compounds. The sulphur dioxide …
Sulphuric acid is a strong mineral acid with the molecular formula H2SO4. It is a highly corrosive acid and is an important industrial chemical, used in the production of fertilizers, explosives, and other chemical products. It is also used in car batteries and to clean metal surfaces.
Catalyst is a substance that can facilitate the reaction rate of a chemical reaction without being consumed or participating in the reaction itself. Chemical equilibrium is a state of balance between the reactants and the products of a chemical reaction. This balance is maintained by the forward and backward reactions occurring at the same rate.
