Does kerosene and petrol form a single layer on mixing?

Yes, they can be homogeneously mixed ('one layer' fluid) in each random ratio, but not with water.


How do you separate petrol and seawater?

Use a separating funnel since the petrol floats above the water.Just let the mixture stand. Petrol and water are not soluble, so they willeventually separate. Since the petrol is lighter than the water, it will forma layer on top, and may be drawn off.Petrol will form at the top of water as it is not as heavy.Apart from this I do not know what industrial methods one can use.Petrol will float on top of the water as it is less dense. Therefore, drawing water only from the bottom will reduce the water content in the mixture. It may take distilling to separate the two completely.Petrol will float on top of the water as it is less dense.

Is petrol man made or natural?

Petrol is extracted from crude oil. The question whether it is man-made or natural is therefore a grey area. The chemicals which make up petrol are natural, however it must be processed by man in order to obtain it in the form we use it.


What are the products formed when fuel such as petrol burns completely?

Mainly Water (H2O), Carbon Dioxide (CO2) and Sulfur Dioxide (SO2), but mainly the first two. And if the petrol is broken down incompletely (without oxygen) Carbon Monoxide (CO) is produced instead of CO2.A:Carbon dioxide and water (mainly) but in case of incomplete combustion carbon monoxide and carbon (soot) too. The pollutants produced by petrol combustion are mainly nitrogen oxides and unburnt petrol.


How long does it take to form Petrol?

Petrol comes from crude oil. When dead organisms are subjected to extremely high pressures for millions of years, the organic compounds in the organisms will transform into hydrocarbons that are present in crude oil. This crude oil is then distilled using fractional distillation to separate different components, such as petrol.
