Question

Which is the main element present in coal and petroleum?

Answer 1

Hint: An element is a substance whose atoms all have an equivalent number of protons: different from claiming this is often that each one of a specific element's atoms have an equivalent number. Elements are chemically the only substances and hence can't be weakened using chemical reactions.

Complete answer:
Carbon is the basic element present in fossil fuels. The organic compounds in coal are composed of the weather carbon, hydrogen, oxygen, nitrogen, sulfur, and trace amounts of a spread of other elements.
Natural gas consists of carbon, hydrogen, nitrogen, sulfur, and oxygen. Petroleum consists of carbon, hydrogen, nitrogen, sulfur, oxygen, and minerals. Coal consists of carbon, hydrogen, nitrogen, sulfur, oxygen, and minerals.
These fossil fuels are then refined into usable substances like petrol, kerosene, etc, formed by the mixture of hydrocarbons and other substances, mainly sulphur. When first collected in its natural form, it's termed as petroleum . This substance is usually characterized by a brownish-black color.
Fossil fuels like Coal, Oil and Gas are a number of the foremost important natural resources that we use everyday. These fossil fuels are all Hydrocarbons, they're compounds formed from only two elements, Carbon and Hydrogen.

Note:
Both coal and oil are fossil fuels. meaning they're formed from organic matter–stuff that was alive on Earth many years ago–that was covered by heavy layers of rock. Over time, the increased pressures and warmth resulting from the overlying rock transformed the decomposed interest coal or oil.
