Hydrogen and Carbon - as the name suggests! They are made up of just hydrogen and carbon atoms. Hydrocarbons in fossil fuels come from the organic matter of organisms which lived 300 million years ago under conditions of extreme pressure and temperature.
Hydrocarbons contains atoms of Hydrogen, Oxygen and Carbon, other atoms may also be present.
Hydrogen and carbon.

These atoms are carbon and hydrogen.

Hydrocarbons end up in the atmosphere when they are burnt
Hydrocarbons. If you're adding Oxygen, it's Sugars.
These compounds are called "hydrocarbons".
Molecules are formed from chemical elements.
They are made of elements
Bread crumbs are hydrocarbons since they come from bread made with wheat.
I can tell you one thing for certain: hydrocarbons aren't elements. They're made of hydrogen and carbon, both of which are elements themselves.
The elements that hydrocarbons contain are: -Hydrogen -Carbons
Hydrocarbons are compounds, not elements, composed of hydrogen and carbon atoms. Elements are pure substances made up of only one type of atom, while compounds contain different types of atoms chemically bonded together.
No, oil is not an element. Oil is a complex mixture of hydrocarbons, which are organic compounds made primarily of hydrogen and carbon atoms. Elements are pure substances made up of one type of atom.
A candle chemically speaking is a mixture, containing substances which are made up of chemical compounds, which in turn are composed of elements. . A candle is made up of a wick- generally cotton (cellulose)- and candle wax which is a mixture of hydrocarbons.
Hydrogen and carbon.

Steel, aluminium, hydrocarbons.
Carbohydrates, Hydrocarbons, or Lipids in Biology.
No, products made from petroleum are generally referred to as petrochemicals, not hydrocarbons. Hydrocarbons are organic compounds made up of hydrogen and carbon atoms, which are typically found in petroleum and natural gas.
Elements are made up of atoms, not molecules. Atoms are the smallest unit of an element that retains its properties. When atoms of different elements combine chemically, they form molecules.
