THE CARBON

THE CARBON

1. Carbon is a chemical element of atomic number 6. It is solid at room temperature.

   • Carbon is found often very pure in nature, in the elemental state, in the allotropic forms of diamond and graphite.
     • Carbon forms two main oxides: carbon monoxide (CO) and carbon dioxide (CO2)
       • Carbon monoxide is formed when carbon or hydrocarbons are burned with a limited supply of oxygen.
         • Carbon dioxide is a colorless and odorless gas.

2. It can be found in nature in crystalline form, as is the case of graphite, diamond and the family of fullerenes and carbon nanotubes.

3. Importance of carbon for life Life on Earth is based on the carbon element

   • Two branches of chemistry focus on the study of carbon-containing compounds - organic chemistry and biochemistry.
     • A carbon chain is able to bind to a large number of molecules and chemical elements

4. Analyze the importance of carbon in the compounds responsible for life.

   • The importance of DNA, from the point of view of the conservation of life, is that they are molecules whose chemical composition allows them to replicate and serve as catalysts in reactions with other molecules
     • The importance of carbon in living beings is based on the fact that it is the chemical element on which the existence of life is based.
       • It is the sixth most abundant element in the universe, participating in formations and astronomical reactions.
   • The human body is composed of 18% carbon, and it has been estimated that all organic life on Earth has as a fundamental basis the presence of carbon.
     • Carbon, in the form of carbon dioxide, is a naturally occurring gas present at the atmospheric level.
     • Carbon is key in photosynthesis, as well as in the natural cycle around living beings.
       • Carbon is also present in the great oceanic bodies of the planet, generally in the form of bicarbonate ions; result of the dissolution of carbon dioxide present in the atmosphere.
         • The carbon undergoes a reaction that makes it go from the gaseous state to the liquid state and then converts to bicarbonate ions.

5. Reflect on the importance of carbon for industry and life

   • The importance of carbon in us living beings is based on the fact that it is the chemical element on which the existence of life is based.
     • On Earth, carbon is abundant and its properties allow it to bond with other elements such as oxygen and hydrogen, forming molecular compounds of great importance.
   • The carbon cycle is in which plants and animals produce and consume organic compounds, the compounds of life.
     • This cycle starts and ends with carbon dioxide, water and energy.
   • Carbon is the element of life. Carbon plays a special role in our planet and occupies an important place in the science of chemistry.
