[Chemistry Class Notes] on What is the Structural Formula of Kerosene? Pdf for Exam

The chemical composition depends on the source. The chemical composition also usually consists of about 10 different hydrocarbons each containing 10 to 16 carbon atoms per molecule. Kerosene is the petroleum distillate and also includes the fractions with boiling points between the 150-degree Celsius and 300-degree celsius. The formula of Kerosene is C12H26−C15H32.

What is a Chemical Formula?

A Chemical Formula is any of the several kinds of expressions of the composition or the structure of Chemical compounds. The forms that are commonly encountered are either empirical, molecular, structural as well as projection formulas. 

An empirical formula always consists of symbols representing the elements in a compound like the Na for Sodium and the Cl for Chlorine and subscripts indicating the relative number of the atoms of each constituent element. A subscript is never used until the number is more than one. 

Therefore benzene is represented by the empirical formula CH, which also indicates that the typical sample of the compound contains one atom of carbon to one atom of hydrogen. Carbon is represented as C and hydrogen is represented as H. 

Water is therefore represented by the empirical formula H2O, denoting the substance containing two atoms of hydrogen for every oxygen. 

What is a General Formula?

A general formula type is the type of empirical formula that represents the composition of any member of the entire class of the compounds.  Each and every member of the class of the paraffin hydrocarbons is an example composed of hydrogen as well as carbon. The number of hydrogen atoms always being two or more than twice the number of carbon atoms. That n stands for any number and the general formula of this class is hence CnH2n + 2 .

Kerosene as Solvent

As a petroleum based hydrocarbon compound, the Kerosene is found to be miscible with many industrial liquids, hence its use as an Solvent for various activities arises. As the Solvent, Kerosene can also be used to remove other petroleum products from a surface, such as chain grease and also as a lubricant, with less risk of combustion than the other similar hydrocarbons like the gasoline. It can also be able to perform as a cooling agent in the process of manufacturing and treatment of metals.

As a Solvent the compound Kerosene can be used in the ways mentioned below – 

• One of the famous ways one might have heard that the use of Kerosene is to store the hyper reactive metal like the sodium and the potassium.

• It is also used as the adhesive remover for the hard to remove mucilage or adhesive especially the one left by the sticker on a glass surface.

• It is also used to remove the previous lubricant and clean the bicycle and motorcycle chains before the process of re – lubrication.
