The vast majority of hydrocarbons found on Earth occur in crude oil, petroleum, coal, and natural gas. Petroleum (literally "rock oil") and coal are generally thought to be products of decomposition of organic matter. Coal, in contrast to petroleum, is richer in carbon and poorer in hydrogen. Natural gas is the product of methanogenesis. WebNitrogen dioxide (NO 2) is a reddish-brown gas that is soluble in water, and a strong oxidant. Ambient sources of NO 2 results from high temperature combustion of fuels in …
