- Q: What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?
- Oxygenated derivatives are: methyl ether, methyl ethyl ether, formaldehyde, ethylene oxide;
- Q: Ionic compounds, covalent compounds, electrolytes, non-electrolytes, which are both compounds and inorganic compounds
- They are different concepts -
- Q: Why the silicon hydride less, a lot of hydrocarbons. (Why did not you find silicon-based creatures) and why are so many oxides of silicon, little carbon oxides?
- Silicon oxide than carbon, because the outermost layer of silicon has three levels ah, (SiO, SiO2, Si2O6) silicon less organic matter, the front also said that the organic instability of silicon
- 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: Identification of Derivatives of Chemical Hydrocarbons in High School
- Phenol and ferric chloride reaction, aldehyde and copper hydroxide will produce brick red precipitation, and the formation of silver diamine hydroxide silver phase precipitation, and there are aldehydes in formic acid, an aldehyde corresponding to two silver Generation, and formaldehyde can be seen as there are two aldehyde groups, can be generated corresponding to the four silver quality.
- Q: Is not organic matter must not hydrogen ah?
- Not without hydrogen, there must be C, but the material containing C is incomplete organic matter. Like H2CO3 and carbonate
- Q: What is "organic" and "inorganic" in chemistry?
- The definition of organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.
- Q: How to do it? Solve Inorganic Chemistry
- Inorganic chemistry is one of the earliest disciplines in the development of chemical science. It undertakes a major task of studying the composition, structure, properties and reactions of all elements and elements (except hydrocarbons and derivatives). The current development of inorganic chemistry has two distinct trends, that is, in the breadth of the broadening and depth of the advance. It is the three pillars of modern civilization
- Q: Peracetic acid is not
- A series of compounds produced by the substitution of hydrogen atoms in other molecular or atomic groups as hydrocarbon derivatives, peroxyacetic acid is CH3COOOH, and should be considered
- 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
