In the field of chemistry, commonly used international naming rules are used to better identify and describe the properties and characteristics of chemical substances. For example, chemical substances are usually named according to their constituent elements, structures, functions or properties.
But if you say n888 1br is the name of a specific commercial product or patented compound, then you need more specific information to provide a detailed explanation. Therefore, please provide more background information about n888 1br, such as its industry, use, manufacturer or any other relevant background, so as to answer your question more accurately.
Extended content:
Chemical substance is a kind of substance, which can be divided into known chemical substances and unknown chemical substances. Known chemical substances can be represented by elements in the periodic table or their combinations, and can be divided into two categories: simple substances and compounds.
What are the commonly used chemicals?
1, sodium chloride
Sodium chloride is an inorganic ionic compound with the chemical formula of NaCl, which is colorless cubic crystal or fine-grained powder and has a salty taste. The appearance is white crystal, and its source is mainly seawater, which is the main component of salt.
2. Calcium oxide
Calcium oxide is an inorganic compound with chemical formula of CaO, commonly known as quicklime. Physical properties: the surface is white powder, grayish white when it is impure, pale yellow or gray when it contains impurities, and it is hygroscopic.
3. Calcium hydroxide
Calcium hydroxide is an inorganic compound, commonly known as hydrated lime or hydrated lime, which is a white hexagonal powder crystal.
4. Methane
Methane is the simplest organic matter and the hydrocarbon with the smallest carbon content (the largest hydrogen content). Methane is widely distributed in nature and is the main component of natural gas, biogas and biogas (commonly known as gas).
5. Graphite
Graphite is an allotrope of carbon, which is a gray-black opaque solid with stable chemical properties, corrosion resistance and difficult to react with chemicals such as acid and alkali. Natural graphite comes from graphite deposits, and can also be made from petroleum coke and pitch coke through a series of processes.
