Is SO2 elemental and is SO2 elemental or compound

SO2 is not elemental, and the definition of elemental matter must be known first.

A pure substance composed of only one element.

SO2 in which oxygen is -2 valence and sulfur is +4 valence.

Sulfur is in the intermediate valence state, -2).

Therefore, SO2 has reducing and oxidizing properties.

Elemental matter is a pure substance with only one element.

SO2 has two elements, S and O, which are not elemental but mixtures.

The valency of the elemental element is 0

In SO2, S is +4 valence, O is -2 valence!

SO2 is produced by the mixture of two chemical elements, S and O, which have different properties, so it is not elemental.

There should be no valency.

The elemental substance must be a pure substance composed of the same element, and the mixture cannot be elemental. SO2 is a compound made up of two chemical elements.

No, the so-called elemental matter is composed of only one element.

It is a compound because it has two elements, S and O.

Elemental matter is a pure substance composed of only one element.

It must be a pure substance composed of the same elements, and the mixture cannot be elemental. The presence of an element in a elemental substance is called the free state of the element.

In contrast to elemental substances, pure substances that are made up of a variety of elements are called compounds. Most substances in nature are chemical compounds.

SO2 is a chemical compound because it is made up of a variety of elements.

s is +4 o is -2

Definitely not! Because it is made up of two elements.

S8 is an elemental element of sulfur, an allotrope of sulfur, a molecular crystal, in which each S atom forms an S-S single bond with the other 2 S atoms. The molecular formula is elemental and is a cyclic or coronal structure molecule. In this cyclic molecule, each sulfur atom is connected by a sp3 hybrid orbital to form a covalent bond with two other sulfur atoms.

The schematic diagram of the annular structure of the S8 molecule is shown in the figure below: Burning Qina.

While the P orbital of oxygen is easily overlapped shoulder to shoulder to generate pie bonds, more stable than long chains. So oxygen generally exists in the form of O2, O3.

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

Elemental sulfur is usually a yellow crystal, also known as sulfur. There are many kinds of allotropes of sulfur element, including orthorhombic sulfur, monoclinic sulfur and elastic sulfur. The element sulfur is found in nature in the form of sulfides, sulfates, or elementals.

Sulfur is an important component of proteins in the human body and is of great significance to human life activities.

Sulfur is mainly used in the production of fertilizers, gunpowder, lubricants, pesticides and antifungals. Sulfur is insoluble in water, slightly soluble in ethanol, and soluble in carbon disulfide. The sulfur dioxide (s+O2=ignition=SO2) produced by the combustion of sulfur and sulfur-containing ores combines with water in the air to form sulfurous acid, and the sulfurous acid reacts with the oxygen in the air to form sulfuric acid, thus causing sulfuric acid rain.

To humans, natural elemental sulfur is non-toxic and harmless, while dilute sulfuric acid, sulfate, sulfurous acid and sulfite are toxic, and sulfides are usually highly toxic. Concentrated sulfuric acid will corrode the skin and not the human body**.

Sulfur is important in industry, for example as sulfuric acid in batteries or in solution. Sulfur was used to make gunpowder. It is used as a vulcanizing agent in the rubber industry.

Sulfur is also used to kill fungi and used as fertilizer. Sulfides are used for bleaching in the paper industry. Sulfates also have uses in pyrotechnics.

Sodium thiosulfate and ammonia thiosulfate are used as fixers and fertilizers in photography. Manufacture of sulfuric acid, sulfites, pesticides, plastics, enamels, synthetic dyes, rubber vulcanization, bleaching, medicines, paints, sulfur ointments, etc. The main use of sulfur minerals is in the production of sulphuric acid and sulphur.

Sulfuric acid is a major consumer of sulfur, with more than 70% of sulfur in China used in sulfuric acid production. Chemical fertilizer is the largest consumer of sulfuric acid, accounting for more than 70% of the total amount of sulfuric acid, especially phosphate fertilizer consumes the most sulfuric acid, and the increase is also the largest. In addition to being used in chemical fertilizers, sulfuric acid is also used to make more than 90 kinds of chemical products such as phenol and potassium sulfate; bicycle and leather industry of light industry system; viscose, fiber, vinylon and other products of textile systems; steel pickling and fluorine salt production departments for metallurgical systems; The processing of petroleum systems, petroleum catalysts, additives and the pharmaceutical industry are inseparable from sulfuric acid.

1. SO2 represents a sulfur dioxide molecule. 2. SO2 indicates that sulfur dioxide is composed of sulfur and oxygen, 3, SO2 denotes.

A sulfur dioxide molecule is made up of two oxygen atoms and one sulfur atom. 4. SO2 represents sulfur dioxide. 5. SO2 can also represent the mass ratio of sulfur and oxygen in sulfur dioxide molecule to 1:1

1. Refers to sulfur dioxide.

2. Refers to a sulfur dioxide molecule.

3. It means that sulfur dioxide is composed of oxygen and sulfur elements, and the ratio is 1:24, indicating that a sulfur dioxide molecule is composed of one sulfur atom and 2 oxygen atoms 5, referring to the molecular formula of sulfur dioxide.

Sulfur dioxide, sulfite group, and then I don't know anymore =—=

But let's talk about it.

For example, 1 sulfur dioxide molecule has 1 S atom and 2 O atoms, and sulfur dioxide is composed of oxygen and sulfur.

sulfur dioxide).

An SO2 molecule is composed of 1 sulfur atom and 2 oxygen atoms.

Molecules are made up of sulfur atoms and oxygen atoms.

It is composed of two elements, sulfur and oxygen.

The question itself is a bit problematic.

There are four properties: oxidizing, reducing, bleaching, acidic oxide properties.

What exactly is the topic? What does meaning mean?

2. Chemical properties of sulfur dioxide (anhydride of sulfurous acid, both oxidizing and reducing, bleaching) 1 Reaction of SO2 with water.

so2+h2oh2so3

This is a reversible reaction).

H2SO3 is an unstable dibasic weak acid (weakly acidic) with the general properties of acidic oxides.

Reaction with basic oxide: SO2 + Na2O = Na2SO3 and reaction with alkali: SO2 + 2NaOH = Na2SO3 + H2OSO2 + NaOH = NaHSO3

SO2 overdose).

3 Catalytic oxidation of SO2.

so3＋h2o==h2so4

SO3 is a colorless solid with a lower melting point (and boiling point (). SO3 reacts with H2O to form H2SO4, which simultaneously releases a large amount of heat. ）

In industrial production, the above two reactions are often used to produce sulfuric acid.

4 Bleaching properties of SO2.

SO2 bleaches certain colored substances.

The presence of SO2 is tested by fading the magenta solution (compounds that are formed by synthesis and returning to their original red color after heating).

5 SO2 has both oxidizing and reducing properties (mainly reducing properties) (1) Strong reduction:

SO2 can discolor chlorine water, bromine water and KMno4 solution, which reflects the strong reducing property of SO2 rather than bleaching.

2) Weak oxidation:

The ratio of the amount of oxidation products to the reduction product species is 2:1) The physical properties of SO3.

SO3 is a colorless and volatile crystal with a melting point and a boiling point.

Sulfur dioxide is bleaching. Sulfur dioxide is commonly used in industry to bleach pulp, wool, silk, straw hats, etc. The bleaching effect of sulphur dioxide is due to the fact that it (sulphurous acid) can form unstable colorless substances with certain colored substances.

This colorless substance easily decomposes and the colored substance returns to its original color, so the straw hat braid bleached with sulfur dioxide turns yellow over time. The bleaching effect of sulfur dioxide and some sulfur-containing compounds is also illegally used by some unscrupulous manufacturers to process food to whiten food. Eating this kind of food has serious damage to the liver, kidneys, etc., and has carcinogenic effects.

In addition, sulphur dioxide inhibits the growth of mold and bacteria, and can be used as a preservative in food and dried fruits. However, it must be used in strict accordance with the relevant national scope and standards.
