Every moment in our daily life some changes happen. For example, the formation of curd from milk or curdling of milk, rusting of iron, all these substances undergo changes as a result of chemical reaction. In today’s article we chemical reaction in Hindi And learn in detail about expressing the equation.
What is a chemical reaction- What is chemical reaction in Hindi
Two or more atoms combine to form a molecule. When a substance combines with another substance. Then the molecules of those substances break into atoms and the reorganization of these atoms to form molecules of different substances. we do this process chemical reaction it is said.
the substance chemical reaction By participating in the formation of new substances, they are called reactants. And the new substance formed as a result of a chemical reaction is called a byproduct.
How do chemical reactions work- How does chemical reaction work in Hindi
any chemical reaction Molecules of the substances participating in it are first broken down into atoms. Then these atoms join together to form the molecules of the byproduct.
In these processes, the molecules of the reactant atoms The bonding forces between the atoms are broken and as a result of the reaction new bonds are formed between the atoms. As a result of which a new substance is created.
Characteristics of chemical reactions in hindi
The following are the characteristics of a chemical reaction:
1) Origin of gas-
Some chemical reactions are like this. In which gas is produced – reaction of zinc hydrochloric acid When heated, hydrogen gas is produced. Or when sodium carbonate is reacted with hydrochloric acid, carbon dioxide gas is produced.
2) Precipitation or formation of new substances-
A precipitate is a solid substance that separates from a solution as a result of a chemical reaction. like-Sodium chloride Silver chloride precipitate is obtained when silver nitrate is added to an aqueous solution of
3) Change in state-
The state of substances also changes as a result of some chemical reaction. For example, when a candle is lit, some part of the wax liquefies and falls down and that part gets converted into vapor.
What is chemical equation- What is chemical equation in Hindi
All chemical reactions are represented by chemical equations. Definition – “Short representation of a chemical reaction with the help of symbols and formulas of substances participating in that reaction”. chemical equation It is called
There are two types of chemical equations- Two types of chemical reaction in Hindi
1) Balanced chemical equation-
Balanced chemical equation One in which the number of atoms of the elements is the same on both sides of the equation. For example -H2 + Cl2 = 2HCl.
2) Unbalanced chemical equation-
An unbalanced chemical equation is one in which both the elements of the equation do not have the same number of atoms. For example -H2 + O2 = H2O.
Benefits of chemical equation in Hindi
1) any chemical reaction It is easy to represent in the form of an equation. This saves time and requires less space on the paper for writing.
2) With the help of chemical equation, the mass of the reactants required to form a certain amount of a new substance can be precisely calculated.
3) Same type of chemical symbols are used all over the world. because of which scientists There is no difficulty in getting the knowledge of chemical equation.
Different types of chemical reaction – Different types of chemical reaction in Hindi
Chemical reactions are divided into several parts on the basis of their nature. Below we present some of the main chemical reactions will learn about
1) planning or synthesis reaction – combination or synthesis chemical reaction in Hindi
A combination or synthesis reaction is one in which two or more substances combine to form a new substance. The properties of the new substance are completely different from the properties of the original substance. Eg – C + O2 = CO2
2) Decomposition chemical reaction
Decomposition or decomposition is a reaction and reaction in which the breakdown of a large molecule of a compound to form two or more compounds whose properties are completely different from the properties of the compound. This reaction is just opposite to the combination reaction. eg -CaCO3 = CaO + CO2
Some metals decompose when an electric current is passed through their oxides or chlorides, in this reaction the metal is liberated at the cathode and oxygen or chlorine gas is liberated at the anode. Eg – 2NaCl = 2Na + Cl2
4) Single displacement chemical reaction
The reaction in which an atom or group of atoms present in a compound is displaced by another atom is called single displacement reaction. e.g. -Fe + CuSO4 = FeSO4 + Cu
5) Double displacement chemical reaction
In abhay displacement reaction, two compounds exchange their ions to form two new compounds. e.g. -NaCl + AgNO3 = AgCl + NaNO3
6) precipitation reaction
There is some chemical reaction in which a new substance is separated from the solution in the form of a solid, such a reaction is called precipitation reaction. The solid that separates is called the precipitate. e.g. -NaCl + AgNO3 = AgCl + NaNO3
7) Neutralization reaction- Neutralization chemical reaction in Hindi
The reaction in which an acid reacts with an ash to form a salt and water leads to a neutralization reaction. For example -HCl + NaOH = NaCl + H2O
8) Photochemical reaction – photochemical reaction in Hindi
The way a chemical reaction occurs in the presence of light is called a photochemical reaction.
For example, photosynthesis by plants is an example of a chemical reaction.
6CO2 + 6H2O = C6H12O6 + 6O2
9) Oxidation reduction reaction – Oxidation reduction chemical reaction in Hindi
Oxidation reduction reaction is a special type of chemical reaction that always occurs simultaneously, it is also called redox reaction.
Oxidation- Oxidation is a chemical reaction in which oxygen is added to an element or compound and hydrogen is removed from a compound.
अवकरण(reduction)- Reduction reactions are just the opposite of oxidation, reduction is such a reaction. In which the combination of hydrogen with an element or compound and the removal of oxygen from a compound takes place.
