Anonymous users2024-02-06We all know that human beings need to breathe in existence, that is, to absorb oxygen and exhale carbon dioxide, and at the same time, plants can absorb this carbon dioxide and convert it into oxygenSo many people began to wonder about a question, the earth is rich in resources, will oxygen run out one day, in fact, no, because oxygen can be converted from many other forms, let's analyze it specifically.
First of all, when we were in junior high school chemistry, we already knew that oxygen can be obtained by electrolysis of water, to put it bluntly, it is the substance O2, and the easiest way to get oxygen is the simplest, but the yield is very low, so the industry will not use the method of electrolysis of water, after all, the cost is also very expensive, many chemical equations can get oxygen, and the country also has an oxygen tank, so even if the oxygen becomes less, it can be made artificially, and it is made in large quantities, and then there is the problem of ecosystem conversion. This is a balanced system that guarantees the interbiological needs of the ecology.
Let's think about it, the world is definitely not only human beings need to breathe oxygen, such as wolves, dogs, sheep and other animals need to breathe oxygen, so if oxygen is really used up, it means that many organisms will be extinct, and organisms are related to each other, Einstein once said that even the extinction of small bees will have a huge impact on human life, let alone such a thing.
So nature will definitely not let the oxygen be used up, there are plants in the world, they are responsible for producing oxygen, absorbing carbon dioxide, and there are many types of plants, especially in the deep forest, the air in the morning is really delicious and clear, this is a balance system, and now we are gradually expanding greening, even if there are many trees on the roads of the city, you can ensure a good supply of oxygen, so I think that oxygen will not run out of one day, and the earth's resources are very rich.

Anonymous users2024-02-05I don't think we run out of oxygen, because oxygen is a renewable resource, and almost all plants can produce oxygen, so I don't think we need to worry about oxygen.

Anonymous users2024-02-04At present, the earth's oxygen will not run out, because the earth is an ecosystem, and it will continue to produce oxygen, and the amount of oxygen is very sufficient, so don't worry.

Oxygen is constantly being produced. On the one hand, the photosynthesis of plants produces oxygen, and the survival ability of plants is stronger than that of humans, and it will not die out completely. On the other hand, the largest molecule on Earth is the water molecule.
Theoretically, if the energy is enough to break the hydrogen bonds, the water molecules will break down into hydrogen and oxygen. Therefore, under the irradiation of sunlight, high-energy particles are emitted on the surface of the sea, and oxygen is constantly produced.
Oxygen is chemically more 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 jujube oxidation reactions.
The compounds produced by the reaction (composed of two elements, one of which is oxygen) 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 be violently burned in oxygen to form carbon dioxide and water. In chemistry, the chemical reaction between a substance and oxygen was defined as an oxidation reaction, and a redox reaction refers to a reaction in which electrons are transferred or shifted. Oxygen has the ability to burn and oxidize.
Oxygen
It is a kind of elemental element formed by oxygen, with the chemical formula O2, which is relatively active in chemical properties and can react with oxygen with most elements. It is not very active at room temperature, and it is not easy to interact 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 oxygen atoms second only to fluorine.
Oxygen is a colorless and odorless gas and is the most common elemental form of oxygen. Melting point, boiling point -183 . Not easily soluble in water, about 30ml of oxygen is dissolved in 1L of water. In the air, oxygen accounts for about 21%. Liquid oxygen is sky blue. Oxygenation is a blue crystal.
Oxygen is the most widely distributed in nature, and it is the most abundant element in the mass of the earth's crust. Oxygen is needed for the oxidation of hydrocarbons, the treatment of wastewater, rocket propellants, and the respiration of animals and humans in aviation, aerospace and diving. Animal respiration, combustion, and all oxidation processes, including the decay of organic compounds, consume oxygen.
But the oxygen in the air is constantly replenished by the photosynthesis of plants. In the cutting and welding of metal. It is the mixing of pure oxygen with combustible gas (such as acetylene) to produce a flame at extremely high temperatures, which melts the metal.
Metallurgical processes are inseparable from oxygen. Oxygen is also needed to intensify the production process of nitric acid and sulphuric acid.

Because the vertical stability of the earth's gravity is generally recognized in our daily life, the earth's natural force, that is, the earth's gravity, is commonly known as the "earth's fixed gravity" (also to distinguish particle microgravity). The theory of studying the meaning, function, laws and characteristics of "the earth's natural force, that is, the earth's fixed gravity", is the "earth's fixed gravity", referred to as "the earth's gravity", which is the earth's natural force generated by the earth's material mass as a whole, that is, the earth's gravity, which occurs in and to the center of the sphere, also known as the spherical gravity. The natural force of the earth, that is, the energy of the earth's body (earth) and the earth's outer space (sky) reached by the earth's gravitational force, condenses in the direction of the earth's core, and this cohesion is carried out in a vertical downward way to stabilize the energy of the things it reaches. >>>More
Earth is the third planet in the solar system from the inside to the outside, and it is also the terrestrial planet with the highest diameter, mass, and density in the solar system. It is also often referred to as the world. The Earth is 4,446 billion years old, and a natural satellite, the Moon, orbits the Earth in a 30-day cycle, while the Earth rotates in a cycle of nearly 24 hours and orbits the Sun in a one-year cycle.
The ocean covers 71 of the Earth's surface, and if all the water in the ocean were evenly spread on the Earth's surface, a 2,700-meter-thick hydrosphere would form on the Earth's surface. So some people say that the name of the earth is wrong, and it should be called "water ball". From the origin of life on earth to the formation of human society, from a primitive society with low productivity to a modern society with advanced science and technology, man and water have formed an indissoluble bond. >>>More
Man is a product of nature, but human development takes place in the destruction of nature. The Earth was born about 4.5 billion years ago, and life on Earth occurred about 3.5 billion years ago. The emergence of human beings is only 3 million years old. >>>More
