Petroleum is a naturally occurring complex mixture made up predominantly of carbon and hydrogen compounds, but also frequently containing significant amounts of nitrogen, sulfur, and oxygen together with smaller amounts of nickel, vanadium, and other elements.
Is petroleum a homogeneous or heterogeneous mixture?
Answer: A homogeneous mixture consists of only one phase. … (ii) Petrol, kerosene oil, diesel oil are homogeneous mixtures of various liquid hydrocarbons in only one phase i.e. liquid.
What is petroleum a mixture of?
Petroleum is a mixture of a very large number of different hydrocarbons; the most commonly found molecules are alkanes (paraffins), cycloalkanes (naphthenes), aromatic hydrocarbons, or more complicated chemicals like asphaltenes. … Alkanes with more than 16 carbon atoms can be refined into fuel oil and lubricating oil.
Why petroleum is a heterogeneous mixture?
By definition, a pure substance or a homogeneous mixture consists of a single phase. A heterogeneous mixture consists of two or more phases. … Oil and water do not mix, instead forming two distinct layers called phases. The oil phase is less dense than the water phase, and so the oil floats on top of the water.
Is petroleum jelly a homogeneous mixture?
It is a homogeneous mixture of refined semi-solid hydrocarbons.

How is petroleum made up?
Petroleum is a fossil fuel, meaning that it has been created by the decomposition of organic matter over millions of years. Petroleum is formed when large quantities of dead organisms–primarily zooplankton and algae–underneath sedimentary rock are subjected to intense heat and pressure.
Is sugar and water a heterogeneous mixture?
The sugar-water is a homogenous mixture while the sand-water is a heterogeneous mixture. Both are mixtures, but only the sugar-water can also be called a solution.
Is Vinegar a homogeneous mixture?
Vinegar is a mixture of water and acetic acid, which dissolves in the water. Olive oil and vinegar are homogeneous mixtures. A homogeneous mixture is a mixture in which the composition is uniform throughout. Olive oil and vinegar are homogeneous mixtures.
