Answer: Carbon dioxide (CO2) is a chemical molecule that exists as an acidic, colourless gas with a density of around 53% that of dry air.
A carbon atom is covalently linked to two oxygen atoms in a carbon dioxide molecule. In the Earth’s atmosphere,
It is found as a trace gas. The present concentration is 0.04 percent (412 parts per million) by volume, up from 280 parts per million prior to the industrial revolution.
Natural sources include volcanoes, forest fires, hot springs, and geysers, and it is liberated from carbonate rocks by dissolving in water and acids. Because carbon dioxide is soluble in water, it can be found in groundwater, rivers and lakes, ice caps, glaciers, and the sea. It’s found in petroleum and natural gas reservoirs.
Carbon dioxide has a strong, acidic odour and tastes like soda water in the tongue. It has no odour in normal doses, however. Carbon dioxide is the most readily available carbon in the carbon cycle, and its concentration in the pre-industrial atmosphere has been regulated by photosynthetic organisms and geological events since late in the Precambrian. Photosynthesis is a process in which plants, algae, and cyanobacteria use sunlight to convert carbon dioxide and water into carbohydrates, with oxygen as a byproduct.
Electron dot structures, or Lewis dot formulas, specify the type of bond and the location of atoms in the molecule that are joined. Electron dot structure of carbon dioxide
The core atom of this molecule is carbon.
The valence electrons in an oxygen atom form two lone pairs. It must create a double bond because it is only linked to one carbon atom.
There are no lone pairs because the carbon atom has four valence electrons. As a result, each oxygen atom is doubly linked.
