PETROLEUM (पेट्रोलियम) Petrol At some places in nature, a thick, viscous and dark colored liquid is found under the rock, which mainly contains aliphatic hydrocarbons up to C 1 to C 40 , this fluid is called refined oil or petroleum. The word petroleum is derived from the Latin words petra and olium which is found under rocks within the earth, hence it is also called mineral oil. Within the earth, this fluid floats above the salt solution. A gas atmosphere exists along with the floating petroleum inside the Earth, which is called natural gas. Petroleum is also called liquid gold. In the present era, this fluid is more valuable than gold for any nation. The progress of any nation depends to a large extent on how much petroleum it has. Its use is very important in various tasks like agricultural industry, traffic communication etc. This oil is found in the highest amount in the United States. Russia Venezuela is also found in greater quantities in Mexico, Burma etc. ...
Laws of Chemical Combination
( रासायनिक संयोग के नियम )
When a continuous study of the chemical behavior of the substances, some conclusions were obtained on the basis of the received tests. The statements used to express these findings collectively represent the rules of chemical coincidence.
This rule can also be expressed in this way -
(c) This rule is one of the most fundamental rules of chemistry and on the basis of which the quantitative relations between the substances are interpreted. It is proven on the basis of a landand experiment.
The tube remains after the reaction and after the reaction the mass of the tube.
(1.) Rule of mass conservation: (Lomonosov -1748, Lavoisier-1774)
Law of conservation of mass (Lomonosov -1748, Lavoisier-1774)(a) According to this rule -
"When physical or chemical changes occur in the matter, then measuring the total amount of the body does not make any qualifying change."
"Due to any chemical reaction, the matter is neither produced nor destroyed, although its physical or chemical state changes in this process."
(b) On the basis of this rule, the following findings are obtained for any reaction. -
Total mass of factors just before reaction = total mass of products after reaction(c) This rule is one of the most fundamental rules of chemistry and on the basis of which the quantitative relations between the substances are interpreted. It is proven on the basis of a landand experiment.
Landont's experiment: -
Assumed aqueous solutions of AgNO3 and KI are taken separately in the sides of a H shape tube. Now this tube is mixed by mixing solutions. Where the following reactions occur.The tube remains after the reaction and after the reaction the mass of the tube.
