Stearic Acid 1668

Q: Can the carboxylic acid react with sodium?: can

Q: The main role of sugar?: Carbohydrates as an important body of nutrients, mainly divided into four categories: monosaccharides, disaccharides, oligosaccharides and polysaccharides.

Q: What are the inorganic compounds: The inorganic compound is a compound other than an organic compound. Organic compounds are organic matter containing C (carbon), in addition to CO2, carbonated, carbonate-containing.

Q: What is the difference between organic matter and inorganic matter?: Inorganic matter is an inorganic compound. Generally refers to the elements other than carbon elements, such as water, salt, sulfuric acid, lime and so on. However, some simple carbon compounds such as carbon monoxide, carbon dioxide, carbonates, carbonates and carbides, because of their composition and properties and inorganic similar, so also as an inorganic to study. The vast majority of inorganic matter can be classified as oxides, acids, alkalis and salts.

Q: What happens to the neutralization reaction?: The neutralization reaction takes place with the hydrogen and hydroxide groups of the acid and base. The carboxylic acid group contains hydrogen ions to react with the hydroxide.

Q: Is fatty acid and carboxylic acid the same thing?: In contrast, aromatic acids refer to carboxylic acids with benzene rings

Q: Are hydrocarbons all organic?: A series of organic compounds, also known as "hydrocarbons." Many types, according to the structure and nature,

Q: What is a derivative?: Derivative refers to a compound formed by the substitution of atoms or radicals in a parent compound molecule by other atoms or radicals, known as derivatives of the parent compound. Derivatives named, the general parent compound as the main body, with other groups as a substituent. Such as: halogenated hydrocarbons, alcohols, aldehydes, carboxylic acids can be seen as derivatives of hydrocarbons, because they are hydrogen atoms of hydrocarbons are replaced by halogen, hydroxyl, oxygen and other products

Q: Is the heterocyclic compound not a derivative of cyclic hydrocarbons? why?: Aromatic hydrocarbons referred to as "aromatic", usually refers to the molecules containing benzene ring structure of hydrocarbons. Is a kind of closed-chain class.
