The microscopic difference between carbon monoxide and carbon dioxide

1. Carbon monoxide.

Comparison with the properties of carbon dioxide.

2. Several types of problems that take advantage of the different properties of carbon monoxide and carbon dioxide.

1.Conversion between carbon monoxide and carbon dioxide:

co→co2

1) The methods of converting CO to CO2 are: CO+CUOCU+CO2

2co+o22co2

2) The methods of converting CO2 to CO are: CO2+C2CO

Example: A colorless gas x reacts with red-hot charcoal to obtain another colorless gas y, y reacts with a black solid under heating conditions to obtain x and a red solid, then gases x and y are ().

is co, y is co2, y is co2, y is co

is O2, Y is CO2 is O2, Y is Co

Answer: B2Methods for identifying carbon monoxide from carbon dioxide.

1) Separate the gas into the clarified lime water.

, carbon dioxide is the one that can make the clarified lime water turbid, and carbon monoxide is one that cannot make the clarified lime water turbid;

2) The gas is passed into the purple litmus solution, and carbon dioxide is the one that can make the purple litmus solution red, and carbon monoxide is the one that cannot make the purple litmus solution red;

3) Pass the gas through the hot copper oxide separately.

Carbon monoxide is the one that can make the black powder red, and carbon dioxide is the one that cannot make the black powder red;

4) Ignite the gas separately, carbon monoxide can produce a popping sound, and carbon dioxide can not produce a popping sound;

5) Put the burning wooden strips on the mouth of the gas collection cylinder, the carbon dioxide that can extinguish the flame of the burning wooden strips, and the carbon monoxide that can ignite the gas and produce a blue flame;

6) Carbon monoxide is the one that makes the blood cherry red, and carbon dioxide that makes the blood dark red.

CO2 is composed of obvious carbon-oxygen double bonds, while the CO structure is more complex.

Carbon monoxide and carbon dioxide are microscopically different in molecular structure, chemically speaking, carbon monoxide is reducing, and carbon dioxide is an acidic oxide, which is also oxidizing.

Chemically, carbon dioxide is non-toxic, and carbon monoxide is toxic.

Carbon dioxide can react with soluble bases, but carbon monoxide cannot.

Carbon dioxide reacts with water to form carbonic acid, while carbon monoxide is neither soluble in water nor reacts with water.

Carbon dioxide can react with carbon to form carbon monoxide, which shows its oxidizing properties, while carbon monoxide can seize the oxygen of metal oxides, and convert metal oxides into elemental matter, which shows the reducing property of carbon monoxide.

Carbon dioxide neither burns, nor supports combustion, and carbon monoxide, does not support combustion, but can be burned.

Carbon dioxide and carbon monoxide are two different gases, and what they have in common is that they are both gases at room temperature, and both are composed of two elements, carbon and oxygen. Differences:

Physical properties: 2. Carbon oxide can be soluble in water, non-toxic and colorless. Combustion cannot be done and combustion is not supported.

Solid carbon dioxide, commonly known as dry ice, is commonly used in refrigerants. Carbon monoxide is insoluble in water and toxic. Colorless and odorless.

It is easy to combine with hemoglobin in the human body to cause hypoxia and form carbon monoxide poisoning.

Chemical properties: Carbon monoxide is chemically stable.

It can be burned and combined with oxygen to form carbon dioxide.

Carbon dioxide reacts with water to form carbonic acid, which is unstable and decomposes into water and carbon dioxide. Carbonic acid is a weak acid. In addition, carbon dioxide can also react with a variety of positive ions to form precipitates.

The commonly used method of carbon dioxide firming is to pass carbon dioxide into lime water, lime water becomes turbid, and after adding a sufficient amount of nitric acid, lime water becomes clear, proving that the gas is carbon dioxide.

The reason why the chemical properties of a liter of carbon fibroxide and carbon dioxide are different is that they have different molecular makeup.

A carbon monoxide molecule is one oxygen atom less than a carbon dioxide molecule. The structure of matter determines the properties of matter. Since the valency of the carbon element in carbon dioxide is 4 valence, carbon dioxide can no longer seize oxygen and has no reducibility.

The valency of the carbon element in the carbon monoxide molecule is 2 and can be further oxidized to 4 valence.

Carbon monoxide is not only burned in oxygen to produce carbon dioxide, but also in the air to produce a blue flame. Carbon monoxide also captures oxygen from some metal oxides and is reducible.

Question Analysis:

1) Carbon monoxide is composed of carbon monoxide molecules, while carbon dioxide is composed of carbon dioxide molecules, the molecules of the two are different, and the molecule is the smallest particle that maintains the chemical imitation properties of the substance, and the chemical properties are different when the molecules are different.

2) Substances composed of different kinds of molecules (or atoms) are mixtures, and substances composed of the same kind of molecules (or atoms) are pure substances.

3) Because there is a gap between molecules, and the separation between gas molecules is large, the pump can press air into the football.

The microscopic reason why carbon monoxide and carbon dioxide have different chemical properties is that they differ in molecular makeup.

Carbon monoxide and carbon dioxide are two common substances in life and study life, so why are carbon monoxide and carbon dioxide chemically different?

In fact, carbon monoxide and carbon dioxide are different in terms of chemical reactions and their own characteristics, and the fundamental reason is that the molecular structures that make up carbon monoxide and carbon dioxide are inherently different.

The molecule of carbon monoxide has one less oxygen atom than the molecule of carbon dioxide, which is the fundamental reason for their different properties. Carbon dioxide and carbon monoxide are completely different in terms of how they are formed and how they are reduced.

The chemical properties possessed by carbon monoxide are:

reducibility, flammability and toxicity; Carbon dioxide cannot support combustion, nor can it be burned, and carbon dioxide is not toxic, so the difference between carbon dioxide and carbon monoxide can be seen from this; The properties of matter determine the purpose of the substance, and according to the molecular composition of carbon monoxide and carbon dioxide, it can be known that the structure of the substance determines the properties of the substance.

The molecule is the smallest particle that maintains the chemical properties of the schizole substance, and carbon monoxide is composed of carbon monoxide molecules, and its chemical properties are maintained by carbon monoxide molecules; Carbon dioxide is made up of carbon dioxide molecules, and its chemical properties are maintained by carbon dioxide molecules; A carbon monoxide molecule is made up of one carbon atom and one oxygen atom, and a carbon dioxide molecule is made up of one carbon atom and two oxygen atoms.

The microscopic reasons why carbon monoxide and carbon dioxide are chemically different are as follows:

1) Carbon monoxide is composed of carbon monoxide molecules, and carbon dioxide is composed of carbon dioxide molecules, and the two are different from one oxygen atom in one molecule, and the molecule is the smallest particle that maintains the chemical properties of the substance.

2) The properties of diamond and graphite are different, because the carbon atoms in diamond are arranged in regular octahedron and the relative combination is very strong, resulting in greater hardness, while the carbon atoms in graphite are arranged in layers, and the force between the layers is very small, resulting in softness and smoothness. So the difference between the two is the difference in the way the atoms are arranged.

The chemical properties possessed by carbon monoxide are as follows:

reducibility, flammability and toxicity; Carbon dioxide cannot support combustion, nor can it be burned, and carbon dioxide is not toxic, so the difference between carbon dioxide and carbon monoxide can be seen from this; The properties of the substance determine the purpose of the substance, and according to the molecular composition of carbon monoxide and carbon dioxide, it can be known that the structure of the substance determines the properties of the substance.

While the molecule is the smallest particle that maintains the chemical properties of the substance, carbon monoxide is composed of carbon monoxide molecules, and its chemical properties are maintained by carbon monoxide molecules; Carbon dioxide is made up of carbon dioxide molecules, and its chemical properties are maintained by carbon dioxide molecules; A carbon monoxide molecule is made up of one carbon atom and one oxygen atom, and a carbon dioxide molecule is made up of one carbon atom and two oxygen atoms. <>
