What are the sources of carbon dioxide gas ?
Carbon dioxide gas is a chemical compound which its molecule consists of one carbon atom ( C ) linked with two oxygen ( O ) atoms , it represents 0.03 % of the volume of the atmosphere , It is very necessary for the photosynthesis process of green plants to make their own food , and to build their bodies .
Sources of carbon dioxide gas
The volcanic eruptions release magma , ash , dust and gases from deep below the Earth’s surface , one of the gases released is carbon dioxide , and the most common volcanic gases are water vapor , carbon dioxide , and sulfur dioxide .
Carbon dioxide gas increased due to the human activities such as the burning of oil , coal and natural gas , burning of fossil fuels , clearing of forests , and some industrial processes such as cement manufacturing .
Carbon dioxide gas is produced from the combustion of fuel in the factories and means of transportation , and the largest human source of carbon dioxide emissions is from the combustion of fossil fuels .
Carbon dioxide gas is produced from the combustion of organic materials such as the wood , coal , oil , gasoline , and tobacco ( the material of cigarettes ) .
From the factors that increase the percentage of carbon dioxide gas in air is the respiration process of the human , the animals and the plants , Carbon dioxide gas is produced from decreasing the green areas and removing the forests .
There are industrial processes that produce carbon dioxide gas as the production and consumption of mineral products such as cement , the production of metals such as iron and steel , as well as the production of chemicals and petrochemical products .
Cement production produces the most amount of carbon dioxide amongst all industrial processes , During creating the main ingredient in cement , calcium oxide , limestone is chemically transformed by heating it to very high temperatures ,This process produces large quantities of carbon dioxide as a byproduct of the chemical reaction .
Carbon dioxide gas is produced from steel production , if you want to create steel , iron is melted and refined to lower its carbon content , and oxygen is combine with carbon in iron to form carbon dioxide gas .
Limewater is used to detect the presence of carbon dioxide gas , it turns into milky ( turbid ) when carbon dioxide passes through it due to the formation of a chemical substance called calcium carbonate which is insoluble in the water .
The fossil fuels are used to create the chemicals and petrochemical products which leads to carbon dioxide emissions , and the industrial production of ammonia and hydrogen most often use the natural gas or other fossil fuels as a starting base , creating carbon dioxide in the process .
The petrochemical products like the plastics , the solvents , and the lubricants are created using the petroleum , and these products evaporate , dissolve , or wear out over time releasing even more carbon dioxide during the product’s life .
