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 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: 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?: C (charcoal, graphite)

Q: What is the chemical formula of iodine element?: Iodine, which is located in the periodic period of the chemical element in the 5 cycle. Series VIIA is one of the halogen elements. 1811 French pharmacist Kutwa first found that iodine iodine. Elemental iodine was purple black crystal, easy sublimation, after sublimation easy to Ninghua. Toxic and corrosive. Iodine case of starch will become blue and purple. Mainly used for pharmaceuticals, dyes, iodine, test paper and iodine compounds. Iodine is one of the essential trace elements in the body. The total amount of iodine in healthy adults is 30 mg (20 to 50 mg), and the national standard for adding iodine to salt is 20-30 mg / kg.

Q: Does the mixture have a simple substance? What is it?: Of course there are myself! Such as red phosphorus and white phosphorus mixture, white tin and gray tin mixture, oxygen and ozone mixture, etc., anyway, there are a lot of it! Usually pay attention to accumulation. I hope that my answer is helpful to you and wish you good results!

Q: Is chlorine gas simple?: Yes

Q: What is the elemental? O is a simple element, or O2 is a simple element?: Elementary is the same element of pure ingredients, O2 is simple.

Q: What is the element?: A substance consisting of atoms of an element that is more stable in free form. Such as oxygen (O 2), chlorine (Cl 2), sulfur (S), iron (Fe), and the like. Elementary and element are two different concepts. The elements are collectively referred to as atoms having the same number of nuclear charges (protons). An element may have several elements, such as oxygen (O 2), ozone (O3) tetramerox (O4, a new type of oxygen molecules synthesized by a scientist in Italy). Although any of these substances are simple, because they are pure elements of the same element, but oxygen and ozone together is not pure, they are the same kind of elements of the mixture.

Q: What is HD?: HD should be a special element, solid H2 is the molecular crystal. At room temperature, HD for the gas, does not belong to the crystal.
