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 is carbohydrate? What is organic? What is it?
Organic compounds contain hydrogen, oxygen, carbon three elements, and the proportion of hydrogen and oxygen in accordance with the composition of the water called carbohydrates. Organic matter is a compound containing carbon, but does not include carbon elements and their allotypes and carbon dioxide and carbonates. The inorganic matter is a carbon-free compound
Q:What is the relationship between hydrocarbon and hydrocarbon derivatives?
Hydrocarbons, which are composed of two elements, carbon and hydrogen, are called hydrocarbons and hydrocarbons. It reacts with chlorine, bromine vapor, oxygen, etc. to produce hydrocarbons.
Q:Ionic compounds, covalent compounds, electrolytes, non-electrolytes, which are both compounds and inorganic compounds
An ionic compound consisting of a cation and an anion. Active metals (such as sodium, potassium, calcium, magnesium, etc.) and active non-metallic (such as fluorine, chlorine, oxygen, sulfur, etc.) when the combination of active metal loss of electrons to form positively charged cations (such as Na +, K +, Ca2 + (Such as F-, Cl-, O2-, S2-, etc.), cations and anions are formed by electrostatic interactions to form ionic compounds. For example, sodium chloride is an ionic compound consisting of positively charged sodium ions (Na +) and negatively charged chloride ions (Cl-). Many bases (such as NaOH, KOH, Ba (OH) 2, etc.) and salts (such as CaCl2, KNO3, CuSO4, etc.) are ionic compounds. The total number of positive charges in the cationic compound is equal to the total number of negative charges carried by the anion, and the whole compound is electrically neutral. Most ionic compounds can not be conductive in solid (or crystalline), while their aqueous or molten state can be conductive. The ionic compounds generally have a higher melting point and higher boiling point, higher hardness, crisp and difficult to compress, and the highly volatile ionic compounds are linked by ionic bonds, without independent structures, such as sodium chloride.
Q:What is "organic" and "inorganic" in chemistry?
Inorganic compounds are inorganic compounds, usually refers to non-carbon compounds. , Alkali, salt and so on.
Q:What does organic mean?
Food point of view of organic: from planting to harvest, and then to storage, transport so that consumers in the hands, without chemical fertilizers, chemical processing, genetic technology and other food raw materials. In general, organic represents high quality and natural. But the Chinese market is not very close, so the choice of time to pay attention.
Q:Is grease a polymer compound? Is it a derivative of saturated hydrocarbons?
Although the relative molecular mass of oil is large, but does not belong to the polymer compound, the polymer compound should refer to a chain with a base number n of the material. Nor is it a derivative of saturated hydrocarbons. The oil is a non-saturated tallow fatty acid glyceride, and the fat is a saturated glycerol ester of saturated higher fatty acids. The more the double bond, the lower the boiling point
Q:What is the most primitive person on earth?
The process of organic life is roughly divided into three steps: first the original earth simple inorganic compounds to form the original organic matter (hydrocarbons and its simplest derivatives), the second is based on the first step, gradually developed into a complex Organic compounds (sugars, nucleotides, amino acids) and their polymer polysaccharides, nucleic acids and proteins, as well as other organic substances, and the third is that with the evolution of natural conditions on Earth, the above substances are complex interactions, resulting in a metabolic Characteristics, can grow, reproduce, inheritance, variation of the original organic organisms.
Q:The problem of system naming of hydrocarbon derivatives
No, aldehyde is functional group, must be aldehyde for the mother. In addition, when the aldehyde group is a substituent, it is named as a formyl group.
Q:Carbon compounds (except inorganic carbon compounds), hydrocarbons and derivatives of the general term is?
Organic matter
