Respuesta :
STP generates carbon dioxide gas, and the chemical formula of the unknown hydrocarbon is CH2.
When one carbon atom and two oxygen atoms are combined by a chemical molecule, carbon dioxide is created; this chemical element may be found in the atmosphere.
Carbon dioxide is present as a gas at normal temperatures, and it may be freed by human and animal exhalation and utilized by plants to generate food through photosynthesis.
It is a greenhouse gas present in extremely low quantities that are released by hydrocarbon fuels such as the combustion of fossil fuels. Carbon dioxide and water vapor are formed when carbon reacts with oxygen.
Carbon is a major component of biomolecules such as proteins, nucleic acids, and carbohydrates, as well as the carbon cycle.
