The differences between organic matter and inorganic matter are: chemical composition, life properties and reaction characteristics.
1. chemical composition: organic matter is mainly composed of carbon-containing compounds, in which the chemical bond formed by carbon and hydrogen, oxygen, nitrogen and other elements is its characteristic. Inorganic substances do not necessarily contain carbon. They are usually composed of inorganic elements or ions, such as metals, nonmetals, oxides and salts.
2. Nature of life: Organic matters play an important role in the life system, including protein, nucleic acids, carbohydrates, etc. They are the basic components of organisms and participate in all aspects of life activities. Inorganic substances play a relatively small role in the life system. Although some inorganic substances participate in the metabolic process of organisms, they are not as important as organic substances in the composition and maintenance of life.
3. Reaction characteristics: Organic compounds usually have complex molecular structures and various chemical reaction properties, such as esterification, reduction and oxidation. In contrast, the molecular structure of inorganic substances is relatively simple, and their chemical reaction properties are usually simple and direct, such as the dissolution of compounds, acid-base neutralization and so on.
characteristics of inorganic substances:
1. stability: inorganic substances usually have high stability and are not easily affected by environmental factors such as heat, light, oxidation, reduction and moisture.
2. Hardness: Some compounds in inorganic substances, such as metal oxides and silicates, have high hardness and strength, and have good compressive and tensile properties.
3. conductivity: some inorganic substances, such as metals and salts, have good conductivity in solid or solution and can conduct current.
4. Solubility: Inorganic substances are widely soluble, and can be dissolved in solvents such as water, acid and alkali to form solutions or ions.
5. reactivity: inorganic substances show rich reactivity in chemical reactions, including acid-base reactions, redox reactions, complex reactions, etc.
6. Diversity: There are many kinds of inorganic substances, including metallic elements, nonmetallic elements, oxides, salts, acids and alkalis, covering a wide range of substances.
