2. Main Features of Calcium Carbide：

This product is lumpy substance, its surface is a little deep gray, has slight nasty smell. It can produce acetylene gas when met water, it can burn when meets fire. The acetylene gas mix with air will form explosive gas (explosive range of acetylene gas in the air is 2.3% - 81%).

Q: Oxygen is not simple: Yes. Because there is only one element of pure matter

Q: What are the different elements of the same element?: The same type of body, refers to the same single chemical elements, but the nature is not the same element. The difference in the nature of the allotropes is mainly manifested in the physical properties, chemical properties also have a difference in activity. Such as phosphorus, two kinds of allotropes, red phosphorus and white phosphorus, their ignition points are 240 and 40 degrees Celsius, after the full combustion of the product are phosphorus pentoxide; white phosphorus (P4) is highly toxic, soluble in carbon disulfide, Red phosphorus (Pn) is non-toxic but insoluble in carbon disulfide. Allotropes can be transformed from each other under certain conditions, and this transformation is a chemical change.

Q: What is the common substance oxide in junior middle school chemistry: Oxides: calcium oxide, sodium oxide, carbon dioxide, phosphorus pentoxide, carbon monoxide, hydrogen peroxide, water, nitrogen dioxide, sulfur dioxide, sulfur trioxide, iron oxide, alumina, silica and the like.

Q: What is the difference between chemical monomer and elemental: The chemical monomer is a low molecular weight compound used to synthesize the polymer, which is a diluent in UV, which belongs to a reactive diluent and is capable of participating in film formation and has a significant effect on the properties after curing.

Q: What is a compound?: Compounds are sub-states called molecular compounds, such as water, sugar and so on. Compounds are ionically bonded as ionic compounds, such as salt, mirabilite and the like. The compound may be represented by a chemical formula consisting of the symbols of the elements contained in the compound. For example, binary compounds consisting of two elements, in writing their chemical formula, as the name of its English name, metal elements written in the former, and less metal followed. Such as salt (sodium chloride) chemical formula for the NaCl. When the number of atoms in the different elements of the compound is not equal, the ratio can be written under the symbol. If the chemical formula of sucrose is C12H33O11, it means that the sugar consists of twelve carbon atoms, twenty-two hydrogen atoms, and eleven oxygen atoms.

Q: Diamond graphite c60 are simple elements do?: Diamond, graphite, C60 are composed of carbon elements of the elemental, diamond, graphite is composed of carbon atoms, C60 is composed of molecules that C60 molecules, diamond and graphite due to the different arrangement of carbon atoms so there is a great physical properties Differences, the diamond is the natural existence of the most hardest material, graphite can be conductive to do the electrode, activated carbon and charcoal can adsorb toxic gases and pigments, carbon simple chemical properties similar to both flammability and reductive, combustion to produce carbon dioxide.

Q: Elementary is a few years of course: Elementary is the first three years of chemistry

Q: What are the black solid elements in junior high school chemistry?: Carbon (C), iron powder (Fe), ferrous oxide (FeO), charcoal (carbon black, activated carbon), copper oxide (CuO), manganese dioxide (MnO2), iron tetraoxide (Fe3O4)
