State the formation of carbon dioxide as a product of complete combustion of carbon-containing products

Fossil fuels contain carbon (C) and hydrogen (H). During complete combustion carbon and hydrogen combine with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). During incomplete combustion part of the carbon is not completely oxidized producing soot or carbon monoxide (CO).

Explanation: i think this is the answer

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
