Q:How to identify carboxylic acid and anhydride

Carboxylic acid and chlorinated sulfuryl chloride or oxalyl chloride reaction can be converted to acid chloride;

Q:How to distinguish between inorganic chemicals and organic chemicals

Hydrocarbons and their derivatives are organic chemicals. There are carbon and hydrogen compounds, in addition to carbonic acid series, cyanide series of things, carbon oxides, the rest you can think of are organic compounds, these compounds as the main ingredient of the chemical is organic chemicals. Inorganic chemistry focuses on the study of the structure and properties of inorganic matter and its use, and is devoted to the study of organic matter (carbon) in all aspects of knowledge. Inorganic and life closer, organic and industrial and agricultural production more closely.

Q:Calcium fatty acid is an organic or inorganic chemical

All fatty acids are organic chemicals

Q:Carboxylic acid and alcohol can react, is it necessary to have certain conditions, if the conditions can not reach, is not it can not respond?

This is not you know the wine wine fruit flavor from ethyl acetate it is ethanol and acetic acid esterification out of the esterification of the esterification reaction needs to concentrate sulfuric acid catalysis that is because the laboratory to yield to the speed So it is necessary to reduce the activation energy to try their esterification but miscible case will react but very very slow wine more Chen Yue Hong to wait ten years or even hundreds of you will not be willing to do so

Q:What are the derivatives of hydrocarbons?

In addition to the C and H elements, there are also one or more of O, X (halogen), N, S and other elements, such as methanol (CH3OH) learned from junior high school chemistry, (CH3Cl), nitrobenzene (C6H5NO2), and the like, which are mentioned in the previous chapter, are derivatives of hydrocarbons, such as ethanol (C2H5OH), acetic acid (CH3COOH)

Q:From the molecular level, are not all the energy obtained from the redox reaction?

Because one to be recycled, and secondly to be converted into electricity

Q:Are the asphalt and peat kinds of vegetables have heavy metal?

Asphalt is composed of different molecular weight hydrocarbons and non-metallic derivatives of dark brown complex mixture, is a high viscosity organic liquid, was liquid, the surface was black, soluble in carbon disulfide. Asphalt is a waterproof moisture and corrosion of organic cementitious materials. Asphalt can be divided into coal tar pitch, petroleum asphalt and natural asphalt three: Among them, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural asphalt is stored in the ground, and some of the formation of ore or in the crustal surface accumulation. Asphalt is mainly used for coatings, plastics, rubber and other industries and pavement and so on.

Q:Storage of organic chemicals in the warehouse, ventilation requirements

The use of anti-static ventilation fan ventilation.

Q:Carbon compounds (except inorganic carbon compounds), hydrocarbons and derivatives of the general term is?

Organic matter

Q:Chemical life network: chemical (inorganic reaction, organic reaction) is equal to the life of life reaction?

Inorganic chemistry is the science of the composition, nature, structure and reaction of inorganic substances. It is the oldest branch of chemistry. All inorganic substances include all chemical elements and their compounds, except for most of the carbon compounds (except for carbon dioxide, Carbon monoxide, carbon disulfide, carbonates and other simple carbon compounds are still inorganic substances, the rest are organic matter.
