What is the chemical formula of sulfide oxidation, sulfur oxygen and sulfur dioxide?

Aluminium sulfide chemical formula Al2S3, molecular weight. The pure product is a white needle-like crystal, and the impurity usually seen is a yellowish-gray dense substance. With a density melting point of 1100, aluminum sulfide is completely hydrolyzed in hot water to produce aluminum hydroxide precipitate and hydrogen sulfide.

It can also be hydrolyzed in moist air, so it has a hydrogen sulfide odor. This product can not be prepared by salt solution method, mixed aluminum powder with sulfur into a large crucible, and ignited the mixture with ignited magnesium strips.

The only preparation method: 2Al+3S== ==Al2S3 (Al2S3 cannot exist in aqueous solution).

Upstairs answered hydrogen sulfide.

Oxygen sulfide? Generally not so.

Generally speaking, sulfur oxide.

Oxygen is usually put in front.

And because the valence of sulfur is different.

Divided into sulfur dioxide, sulfur trioxide.

The chemical formula is SO2, SO3

Now I dare to say that, 1, is you taking it out of context, for example, the word appears in the name of a certain compound, such as molybdenum oxysulfide dithiophosphate.

2. There was a problem with printing, I searched for entries on the Internet, and I did find an entry for oxygen sulfide, but after my own discovery, it was hydrogen sulfide, and the problem printed should be hydrogen sulfide.

3. Let me tell you, why is it not oxygen sulfide, because, when naming inorganic substances, it is usually thought that the highly reducing is pronounced after the strong oxidizing, such as hydrogen oxide and mercury sulfide.

According to the structure of sulfur atoms, when it encounters oxygen, it generally exhibits volatile electrons, that is, reducibility, and oxygen obtains electrons, that is, oxidation, so it should be said to be sulfur oxide, which is conventional!

I suggest that you type out this topic as a whole, and let us take you through the analysis, so we can only guess!

The oxides of sulfur are sulfur monoxide (SO), sulfur trioxide (S2O3), sulfur dioxide (SO2), sulfur trioxide (SO3), sulfur heptaoxide (S2O7) and sulfur tetroxide (SO4), with sulfur dioxide (sulfurous anhydride) and sulfur trioxide (sulfuric anhydride) being the most important.

Sulfur + oxygenSulfur dioxideThe chemical formula is: S+O2=SO2.

At room temperature, humid sulphur dioxide and hydrogen sulfide.

The reaction precipitates sulfur. At high temperature and in the presence of catalysts, it can be reduced by hydrogen to hydrogen sulfide and carbon monoxide.

Reduced to sulfur. Strong oxidizing agents can oxidize sulfur dioxide to sulfur trioxide.

Oxygen can oxidize sulfur dioxide to sulfur trioxide only in the presence of a catalytic pyrude. It has spontaneous combustion, non-combustibility. Liquid sulfur dioxide can dissolve amines, ethers, alcohols, phenols, organic acids, aromatic hydrocarbons.

and other hand-prepared organic compounds, most saturated hydrocarbons.

Insoluble. It has a certain water solubility, and reacts with water and water vapor to form toxic and corrosive vapors.

1. It is used as an organic solvent and refrigerant, and is used to refine various lubricating oils.

2. It is mainly used for the production of sulfur trioxide, sulfuric acid, sulfite, thiosulfate, and is also used as fumigant, preservative, disinfectant rubber agent, reducing agent, etc.

3. Sulfur dioxide is a reductive bleach agent allowed to be used in China. It has a strong inhibitory effect on the bleaching of food and oxidase in plant food. China stipulates that it can be used for wine and fruit wine, and the maximum amount of use and residue shall not be exceeded.

4. Pesticides, man-made fibers, dyes and other industrial sectors.

Sulfur + oxygen Sulfur dioxide, the chemical reaction equation is:

s + o2 ==so2

Sulfur dioxide is formed by combustion reaction in pure air with a coefficient of 1, and sulfur dioxide and oxygen are formed under the condition of catalyst and heating and pressurization.

s。

Sulfur is a non-metallic element, chemical symbol S, atomic number 16, sulfur is one of the oxygen group elements (group A), located in the third period of the periodic table.

Introduction

The English name of sulfur is sulfur, which is derived from the Latin "surphur", and the legend is that the Sanskrit "sulvere" from India is bright yellow. The English prefix "thio-" is derived from the Greek word for "theion" (i.e., sulfur).

Sulfur has been known since ancient times. About 4,000 years ago, the Egyptians used sulfur dioxide from the combustion of sulfur to bleach cloth, and the ancient Greeks and Romans were also skilled at using sulfur dioxide to fumigate and bleach. In the 9th century B.C., the famous Roman poet Homer described in his writings that sulfur burns to disinfect and bleach.

Sulfur is represented by s, and sulfur dioxide, one of the air pollutants, is formed by combustion at room temperature, which can be converted into sulfur trioxide under the action of dust.

The hydrogen sulfide chemical formula is H2S. Sulfur in sulfides is usually 2 valence, hydrogen 1 valence, and the algebraic sum of the valency of the compound is zero, so two hydrogen atoms and one sulfur atom, usually the positive element is written in front, that is, h2s, and 2 is the subscript, which is written in the lower right corner of the hydrogen atom to indicate the number of hydrogen atoms. The chemical formulas of both hydrogen sulfide and hydrosulfuric acid can be expressed in terms of H2S.

Differences(1) Different states: hydrogen sulfide is gaseous at room temperature, while hydrosulfuric acid is liquid at room temperature.

2) Different composition: hydrogen sulfide is a pure substance, composed of only one molecule (hydrogen sulfide molecule); Hydrosulfuric acid is a solution, a mixture of different molecules and ions (hydrogen sulfide molecules, water molecules, H+, S2-, HS-, very small amounts of OH-).

3) Different properties: hydrogen sulfide only shows reducing properties when reacting with other substances, and hydrogen sulfuric acid can exhibit acidity, oxidation and reduction.

The hydrogen sulfide chemical formula is H2S. Hydrogen sulfide is an inorganic compound, the molecular formula is H2S, the molecular weight is, it is a flammable acid gas under standard conditions, colorless, it smells of rotten eggs at low concentrations, and it smells of sulfur when the concentration is very low, and it is highly toxic. The aqueous solution is hydrosulfuric acid, which is weaker acidic, weaker than carbonic acid, but stronger than boric acid.

Soluble in water, soluble in alcohols, petroleum solvents and **.

Hydrogen sulfide gas can be dissolved in water, ethanol or glycerin, and its chemical properties are unstable. Bo Chunyuan is slightly soluble in water to form a weak acid, called "hydrosulfuric acid". The aqueous solution contains hydrosulfate Hs- (in a molloliter solution at 18 degrees Celsius, pka= and sulfur ion S2-.

At first, the clear hydrosulfuric acid will become cloudy after a period of time, because the hydrosulfuric acid will react slowly with the oxygen dissolved in the water to produce elemental sulfur that is insoluble in water.

molecule, which is consistent with the conclusion of the Valence Shell Electron Pair Mutual Exclusion Theory (VSEPR).

In sulfur trioxide, the valency of the sulfur element.

is +6, and the molecule is non-polar. The S in the SO3 molecule has reached +6 valence, all the electrons are involved in bonding, there are no lone pairs, there is no need to leave room for lone pairs, so it is a very symmetrical planar triangle.

Sulfur tetroxide: SO4; Sulfur trioxide: SO3; Sulfur dioxide

so2；Sulfur monoxide: SO. With the development of science and the rapid development of industry, "three wastes.""Emissions increase correspondingly, and there are more and more types of pollution, seriously polluting the atmosphere, water, soil, etc., and the main pollutants that harm forest trees are sulfides such as sulfur monoxide and sulfur dioxide.

Sulfur tetroxide (SO4), an oxide of sulfur, has a +6 valence of sulfur. The two oxygen atoms in the pure pin are -2 valence; The other two oxygen atoms form a single bond with the sulfur atom respectively, and a covalent bond is formed between the two oxygen atoms.

Sulfur tetroxide is an oxidizing agent of metamethylhydrazine C2H8N2 (rocket fuel). It is produced by sulfur trioxide and ozone through photolysis.

Sulfur monoxide Sulfur monoxide is an inorganic compound, a colorless gas, with a special, odor similar to hydrogen sulfide, unstable, and prone to polymerization. The chemical formula is so. It can only be present in the gas phase in low concentrations.

When concentrated or enters the condensed phase, it double-polymerizes into S O (sometimes called sulfur dioxide, sulfur peroxide).
