All the chemical properties of oxygen, the chemical properties of oxygen

It can react with other substances to form oxides (oxidizing), which is combustible, and can react with organic substances to form water and carbon dioxide. And these chemical equations don't know if they count:

Combustion of hydrogen sulfide: 2H2S + 3O2 (excess) = ignition = 2H2O + 2SO2; 2H2S + O2 (a small amount) = ignition = 2H2O + 2S

Calcined pyrite: 4FeS2 + 11O2 = high temperature = 2Fe2O3 + 8SO2 Catalytic oxidation of sulfur dioxide: 2SO2 + O2 = V2O5 and heating = 2SO3

Formation of sulfuric acid rain in the air: 2SO2 + O2 + 2H2O = 2H2SO4 Combustion of ammonia in pure oxygen: 4NH3 + 3O2 (pure) = ignition = 2N2 + 6H2O Catalytic oxidation of ammonia:

4NH3 + 5O2 = platinum catalysis and heating = 4NO+6H2O Reaction of nitric oxide with oxygen: 2NO+O2=2NO2

It shouldn't be flammable, it's flammable.

OxygenChemical propertiesIt can oxidize with metals, non-metals, compounds and other special substances.

It is oxidizing.

It is manifested as slow oxidation, burning, explosion, etc. Substances that are combustible in the air burn more violently in oxygen, and some substances that do not burn in the air can also burn in oxygen.

In addition, almost all organic compounds can be violently burned in oxygen to produce carbon dioxide.

with water. Chemically, it has a chemical reaction between a substance and oxygen.

Defined as oxidation reaction, redox reaction.

Refers to a reaction in which electrons are transferred or shifted. Oxygen is flammable, oxidizing.

In the process of steelmaking, high-purity oxygen is blown, and the oxygen reacts with carbon and phosphorus, sulfur, silicon, etc., which not only reduces the carbon content of the steel, but also helps to remove impurities such as phosphorus, sulfur and silicon.

Moreover, the heat generated during the oxidation process is sufficient to sustain the steelmaking process.

As a result, oxygen blowing not only shortens the smelting time, but also improves the quality of the steel. Blast furnace ironmaking.

, increasing the oxygen concentration in the blast can reduce the coke ratio and increase the yield. In non-ferrous metal smelting, the use of oxygen enrichment can also shorten the smelting time and increase the output.

Oxygen is a strong oxidizing agent, which can oxidize many substances, such as metals, non-metals, organic substances, etc., to produce oxidation products.

Oxygen can react with hydrogen to form water, which is a very important chemical reaction and an important metabolic process in life activities.

Oxygen can form oxides with some elements, such as sulfur, carbon, nitrogen and other elements to form sulfur dioxide, trapped carbon dioxide, nitrogen oxides, etc.

At high temperatures, oxygen reacts with nitrogen to form nitrogen oxide.

Oxygen is able to react with hydrogen at high temperatures and pressures to produce water and energy, which is the basis of nuclear fusion reactions.

In conclusion, oxygen is chemically very reactive, and it plays an important role in many chemical reactions and life activities.

Chemical properties of oxygen:

Oxygen is a chemically active gas, it can oxidize with metals, non-metals, compounds and other special substances, the intensity of the reaction varies according to different conditions, it can be manifested as slow oxidation, burning, explosion, etc., and a large amount of heat is released in the reaction.

1) Oxygen reacts with non-metals.

Charcoal burns violently in oxygen, emits white light, generates colorless, odorless gas that can make the clarified lime water turbid, sulfur burns violently in oxygen, produces a bright blue-purple flame, produces colorless, phosphorus White phosphorus can be slowly oxidized with oxygen in the air, and when it reaches the ignition point (40), it causes spontaneous combustion

Hydrogen is burned in oxygen, producing a light blue flame, and a dry cold beaker is covered in the flame 2) Oxygen reacts with metal.

Magnesium burns violently in the air or in oxygen, emitting a dazzling white light to produce a white powdery substance, and the red-hot iron wire burns in oxygen and sparks to produce a black solid substance.

3) Oxygen reacts with compounds.

Carbon monoxide is burned in oxygen to produce a blue flame that produces a gas that muddies the clarified lime water.

Methane (biogas) is burned in oxygen to produce gas and water that muddy lime water.

Candles burn violently in oxygen to produce carbon dioxide and water.

There is oxygen in the air, and at the same time, oxygen is also a substance that we must have, so do you know the chemical properties of oxygen?

Chemical properties of oxygen:Chemical properties of oxygen: Oxygen is a chemically reactive gas, which provides oxygen in the oxidation reaction, has oxidizing properties, and is a common oxidizing agent. The physical properties of oxygen rolling gas are that, under normal circumstances, oxygen is a colorless and odorless gas, and its density is slightly denser than that of air, and it is not easily soluble in jujube water.

Under certain conditions, it can be liquefied into a light blue liquid or solidified into a light blue solid. The fact that fish and shrimp in the river bench and seawater can survive indicates that there is oxygen dissolved in the water in nature.

Methods of oxygen collectionThere are two ways to collect oxygen:1Drainage gas collection method:

The gas collected by this method is relatively pure; When air bubbles emerge from the edge of the mouth of the gas collection cylinder, it indicates that it has been collected. 2.Upward exhaust air collection method:

During operation, attention should be paid to extending the catheter mouth close to the bottom of the gas collection cylinder, so as to facilitate the exhaustion of the air in the gas collection cylinder. At the same time, the mouth of the gas collection cylinder should be covered with a glass sheet to stabilize the airflow. The gas collected by this method is relatively dry, but the purity is poor, and it needs to be filled.

Oxygen is chemically more reactive. With the exception of rare gases and less reactive metallic elements such as gold, platinum and silver, most elements can react with oxygen.

Oxidation of oxygen.

Oxygen reacts with elemental matter.

Reaction of oxygen with metals (sodium, potassium, calcium, etc.).

Reaction of oxygen with active metals (iron, magnesium, zinc, aluminum, copper, etc.).

Reaction of oxygen with non-metals (sulfur, hydrocarbon, phosphorus, etc.).

Oxygen reacts with compounds.

Reaction of oxygen with oxides (carbon monoxide, nitric oxide, nitrogen dioxide, etc.) Reaction of oxygen with sulfides (hydrogen sulfide, Fes2, etc.).

Oxygen and the combustion of organic matter (almost all organic matter).

Oxidation of oxygen with organic matter (e.g., alcohols oxidized by oxygen to aldehydes) and oxygen reacts with other compounds.

Ammonia followed by oxygen (ignition, catalytic oxidation).

In junior high school, only two points were taught: supporting combustion and supplying breathing.
