Chemical point of view of the similarities between carbon dioxide and oxygen

It's all gas. Both have 2 oxygen molecules.

Example: 2mg+CO2=2MGO+C (ignition condition) C CO2 2CO (high temperature).

Needless to say, O2.

Comparison of the properties of oxygen and carbon dioxide.

Identification method:

Place the extinguished match in a sealed cylinder. If the match is lit again, it burns violently, emitting white light and heat, and produces a gas that makes the lime water cloudy, that is, the oxygen in the cylinder.

The resulting gas enters the clarified lime water and then becomes turbid, proving that the gas is carbon dioxide.

Oxygen is more chemically reactive. With the exception of noble gases and less reactive metallic elements such as gold, platinum, and silver, most elements can react with oxygen. These reactions are called oxidation reactions, and the compounds produced from these reactions, which are made up of two elements, one of which is oxygen, are called oxides.

Comparison of the properties of oxygen and carbon dioxide.

1.Oxygen is a colorless and odorless gas, 2Carbon dioxide is a colorless, odorless, or colorless, odorless, and slightly sour gas at room temperature and pressure.

Second, the use is different.

1. Oxygen. Breath is supplied. For use in hypoxic, hypoxic or anaerobic environments.

2.High-purity carbon dioxide is mainly used in the electronics industry, medical research and clinical diagnosis, three, different chemical formulas.

1.The chemical formula of oxygen is: O.

1. Carbon dioxide is introduced into the clarified lime water respectively, and the lime water becomes turbid;

2. Add the positive burning magnesium strips respectively, and the black solid is carbon dioxide, and the white solid is oxygen;

3. Carbon dioxide is the carbon dioxide that extends into the burning wooden strip and extinguishes the wooden strip;

4. Extend into the wooden strip with sparks, and it is oxygen that rekindles the wooden strip.

Light a bamboo skewer or a piece of paper and put it into a bottle containing oxygen and carbon dioxide gas respectively, if the flame is immediately extinguished, the bottle contains carbon dioxide gas, and vice versa, the bottle with a more intense flame contains oxygen.

A small wooden strip with sparks is inserted into the gas collection cylinder, and oxygen is rekindled, and carbon dioxide is extinguished.

Ignition, the simplest and most practical, oxygen combustion, carbon dioxide fire extinguished.

The similarities between oxygen and carbon dioxide are:

All are oxidizing;

can be reversed with carbon;

All are colorless and odorless gases;

In general, the density is greater than that of air;

The differences between oxygen and carbon dioxide are:

Oxygen is not easily soluble in water, and carbon dioxide is easily soluble in water;

Carbon dioxide is a chemical compound that is the combustion product of carbon or carbon monoxide.

Oxygen is elemental;

It can also absorb carbon dioxide and release oxygen at night, a must-have flower in the bedroom!

Saxivier. Saxivia can absorb harmful gases in the air, not only can absorb carbon dioxide to release oxygen, but also can absorb formaldehyde and other harmful gases, it can also release negative ions to make the indoor environment very good, so Saxiwei is a potted plant that is more suitable for maintenance in the bedroom.

Aloe. Aloe vera is also a plant that can absorb carbon dioxide and release oxygen at night, it can also purify harmful substances such as sulfur dioxide and benzene, aloe vera also has a good bactericidal and anti-inflammatory effect, the taste is also very good, aloe vera can also test indoor air quality, if the indoor pollution is more severe, the leaves will appear black spots, but only need to put a few more pots of aloe vera to be purified.

Crab claw orchid. The crab claw orchid is also known as the "Christmas Cactus", and its bright and diverse flowers add a festive and lively atmosphere to the festival.

Crab claw orchid can absorb carbon dioxide at night, release oxygen, carbon monoxide, nitrogen oxides, and its ability to absorb ammonia is also excellent, and it can increase the concentration of negative ions in the room.

Longevity flowers. The flowers are petite and dotted, can absorb carbon dioxide at night, and have a strong anti-radiation fighting effect.

It prefers a warm, moist and well-lit environment, which is a great setting for both the bedroom and the living room.

In the molecular structure of CO2 and CO, a carbon monoxide molecule is one oxygen atom less than a carbon dioxide molecule, and due to the different composition of the molecules, the nature of their fidder is different.

1. Oxygen, colorless and odorless gas, the most common elemental form of oxygen. Not easily soluble in water, about 30 ml of oxygen is dissolved in 1 liter of water. Oxygen in the air accounts for about 21 percent.

Liquid oxygen is sky blue, and solid oxygen is blue crystals. At room temperature, it is not very smiling and lively, and it is not easy to act with many substances. However, it is very active at high temperatures and can be directly combined with a variety of elements, which is related to the electronegativity of the oxygen atom in the balance marketing second only to fluorine.

2. Carbon dioxide is a common greenhouse gas in the air, which is a gaseous compound, and carbon reacts with oxygen to produce carbon dioxide. A carbon dioxide molecule is made up of two oxygen atoms and one carbon atom through a covalent bond. Carbon dioxide is a colorless, odorless, non-flammable gas at room temperature, denser than air, slightly soluble in water, and reacts with water to form carbonic acid.

Carbon dioxide: Physical properties: It is a colorless and odorless gas at room temperature, slightly denser than air, soluble in water, and produces carbonic acid. Chemical properties: It can make the clarified lime water (Ca(OH)) turbid.

Oxygen: Physical properties: Density in grams and liters under standard conditions (0 and atmospheric pressure 101325 Pa).

Colorless, odorless, tasteless. It has very little solubility in water. At a pressure of 101 kPa, oxygen turns into a pale blue liquid at about -180 degrees Celsius and a snowflake-like pale blue solid at about -218 degrees Celsius.

Chemical properties: The chemical properties of oxygen are relatively reactive. In addition to rare gases and small reactive metal elements such as gold, platinum and silver, most of the elements can react with oxygen, and these reactions are called oxidation reactions, and the compounds produced by the reaction (composed of two elements, one of which is the oxygen element) are called oxides.

In general, aqueous solutions of non-metallic oxides are acidic, while alkali metals or alkaline earth metal oxides are alkaline. In addition, almost all organic compounds can violently ignite carbon dioxide and water in oxygen.
