What Is Carbon Residue?

Carbon is just carbon. Carbon (English carbon, derived from carbo, also known as charcoal) was discovered very early. Common natural forms of carbon are diamond, charcoal, and graphite.

The mass fraction of carbon in the earth's crust is 0.027%, which is widely distributed in nature. Carbon in the form of compounds are coal, oil, natural gas, animal and plant matter, limestone,

Carbon dioxide overview

CO2 is a colorless and odorless gas, accounting for about 0.03% in the atmosphere and 0.014% in the ocean. It also exists in volcanic jets and some springs. The CO2 gas on the ground mainly comes from the combustion of coal, oil, natural gas and other carbon-containing compounds, the decomposition of calcium carbonate ore, animal respiration and fermentation processes. When sunlight passes through the atmosphere, CO2 absorbs infrared rays with a wavelength of 13 ~ 17nm, like covering a huge layer of plastic film on the earth, retaining warm infrared rays, not letting it escape, and making the earth a day and night temperature difference not too disparate. Greenhouse. The greenhouse effect of CO2 provides a comfortable living environment for life. It also provides basic materials for life, and it is the raw material for green plants to perform light and function. Green plants use light and effects each year to convert the 1.5 billion tons of carbon contained in atmospheric CO2 into cellulose, starch, and protein, and emit O2 gas for food for animals and humans.

Green plants have always maintained the balance of O2 and CO2 in the atmosphere, but in recent years, with the rapid development of industries around the world and the resulting marine pollution, CO2 has increased in the atmosphere, and it is estimated that it will increase by about one million points each year. Two to four. This is considered to be an important factor affecting the general rise in world temperature.

Structure of carbon dioxide

In CO2 molecules, carbon atoms are bonded to oxygen atoms using sp hybrid orbitals.

The two sp hybrid orbitals of the C atom each form two delta bonds with an O atom. The two p-orbitals on the C atom that do not participate in hybridization are at right angles to the sp-hybrid orbits, and they overlap side by side with the p-orbital of the oxygen atom, respectively, to generate two delocalized bonds of three central three electrons. Therefore, the distance between carbon and oxygen atoms is shortened, so that the carbon-oxygen bond in CO2 has a certain degree of triple bond characteristics. It is the sp hybrid orbital that determines the molecular shape, and CO2 is a linear molecule.

Carbon monoxide overview

CO is a colorless, odorless, tasteless and toxic gas. The gas density is 1.25g / L under standard conditions, which is smaller than air and difficult to dissolve in water.

Structure of carbon monoxide

The outermost layer of carbon has four electrons. The outermost layer of carbon has six electrons. In this way, two single electrons of carbon enter the p-orbital of oxygen and the two single electrons of oxygen are paired to form a bond. In this way, two bonds are formed. Then the lone electron pair of oxygen enters the empty P orbital of carbon to form a coordination bond, so that three bonds are formed between oxygen and carbon. Its electronic formula is: C ::: O:
