Chemical reaction is a cycle that prompts the compound change of one bunch of synthetic substances into another. Traditionally, synthetic responses include changes that include just the places of electrons in the arrangement and annihilation of compound connections between molecules, without an adjustment in the cores (without a change in the elements present) and can often be described by a chemical equation. Atomic science is a subdiscipline of science that includes the synthetic responses of precarious and radioactive components, where both electronic and atomic changes can happen.
Types of Chemical Reactions
A large number of chemical reactions can be classified in several ways. As per one plan, they can be named oxidation-decrease responses (electron move) or non-oxidation-decrease responses. Another completely different but common classification scheme recognizes four major types of reactions:
(1) combination or synthetic reactions
(2) decomposition reactions
(3) substitution reactions or a single replacement
(4) metathesis or double displacement reactions
The Four Major Types of Reactions are:
Name
General Reaction Pattern
Blend or amalgamation
A + B ----> AB
Decomposition
AB ----> A + B
Replacement or Single Replacement
A + BC ----> B + AC
Metathesis or Double Displacement
AB + CD ----> AD + CB
Blend or Synthesis Reactions at least two reactants join into a solitary item.
S + O2 ---------> SO2
Sulphur oxygen sulphur dioxide
2 S + 3 O2 - > 2 SO3
Sulphur oxygen sulfur trioxide
2 Fe + O 2 - > 2 FeO
Iron oxygen iron (II) oxide
Deterioration responses A solitary reactant is decayed or separated into at least two items.
CaCO3 ----------> CaO + CO2
Calcium carbonate calcium oxide carbon dioxide
Single replacement or substitution responses A solitary free component replaces or is filling in for one of the components of a compound. The free component is more responsive than the one it replaces.
Cu + 2 AgNO3 -----------> 2 Ag + Cu (NO3) 2
silver nitrate copper silver copper (II) nitrate
H2 + 2 AgNO3 - > 2 Ag + 2 HNO3
silver nitric acid
2 Na + 2 H2O -----------> 2 NaOH + H2
sodium water sodium hydroxide hydrogen
Metathesis or twofold relocation responses This kind of response can be considered as a “trade of accomplices”. For ionic mixes, the positive particle in the primary compound joins with the negative particle in the subsequent compound, and the positive particle in the subsequent compound consolidates with the negative ion in the first compound.
HCl + NaOH -----------> NaCl + HOH
sodium hydrochloric water
acid hydroxide chloride
A destructive base reaction is such a twofold movement reaction that occurs between a destructive and a base. The H + particle in the corrosive response with the OH-particle in the base to shape water and an ionic salt:
HA + BOH → H2O + BA
The response between hydrobromic corrosive (HBr) and sodium hydroxide is an illustration of a corrosive base response:
HBr + NaOH → NaBr + H2O
Common types of chemical reactions
There are a few general sorts of synthetic responses that can happen contingent upon what occurs in the change from reagents to items. The most well-known kinds of substance responses are:
Combination
Decomposition
Single trip
Double displacement
Combustion
Redox
Combined chemical reactions
In combined reactions, two or more reagents form one product. The response of sodium and chlorine to shape sodium chloride.
and burning coal (carbon) to carbon dioxide,
are examples of combination reactions.
Chemical decomposition reactions
The deterioration responses are actually something contrary to the joined responses. In decomposition reactions, a compound disintegrates into two or more straightforward substances (components and additionally mixes).
The rot of water into hydrogen and oxygen gases
also, the disintegration of hydrogen peroxide to frame oxygen gas and water
are examples of decomposition reactions.
Single displacement chemical reactions
In single displacement reactions, one more active element displaces (expels) another less active element of a compound. For instance, in the event that you put a piece of zinc metal in an answer of copper (II) sulfate, the zinc uproots the copper, as demonstrated in this condition:
The documentation (aq) demonstrates that the compound is broken up in water - in a aq fluid arrangement. Since zinc replaces copper in this case, it should be more active. If you put a piece of copper in a zinc sulfate solution, nothing will happen.

Double displacement chemical reactions
In single removal responses, just a single synthetic animal type is dislodged.In double relocation reactions or metathesis reactions, two species (regular particles) are uprooted. As a general rule, reactions of this sort occur in a game plan, and either an insoluble solid is molded (precipitation reactions) or water (adjusted reactions).
Precipitation Reactions
In the event that you blend a solution of potassium chloride and a solution of silver nitrate, an insoluble white substance is shaped in the subsequent arrangement. The arrangement of an insoluble strong in an answer is called precipitation.
Here is the atomic condition for this twofold removal response:
The white insoluble strong framed is silver chloride.
Neutralization Reactions
The other sort of twofold dislodging response is the response between a corrosive and a base. This double displacement reaction, known as the neutralization reaction, forms water. Check out the mixed solutions of sulfuric acid (car battery acid) and sodium hydroxide (lye).
Here is the molecular equation for this reaction:
Chemical combustion reactions
Combustion reactions occur when a compound, usually one that contains carbon, combines with the oxygen gas in the air. This process is commonly referred to as burning. Warmth is the most valuable result of most ignition responses.
Here is the equation that represents the combustion of propane:
Propane belongs to a class of compounds called hydrocarbons, which are composed only of carbon and hydrogen. The result of this response is heated.
Burning responses are likewise a sort of redox response.
Redox Chemical Reactions
Redox responses, or reduction-oxidation reactions, are responses in which electrons are traded:
Isomerization
In an isomerization response, the underlying plan of a compound is changed yet its net nuclear synthesis stays as before.
Hydrolysis Reaction
A hydrolysis reaction involves water. The overall type of a hydrolysis response is:
X-(aq) + H2O (l) ↔ HX (aq) + OH-(aq)
Frequently Asked Questions (FAQ)
1. What are the 5 sorts of substance responses?
5 types of chemical reactions are:
Combustion.
Synthesis.
Decomposition.
Single trip.
Double displacement.
Acid-base.
2. What sorts of basic synthetic responses happen in firecrackers?
The straightforward compound responses that happen in firecrackers are ignition and oxidation.
Combustion and oxidation
Ignition responses for the most part require the expansion of warmth and incorporate oxygen as a reactant. Oxidation is the process of losing electrons from an element (or generally gaining oxygen from a chemical). It should be noted that oxidation is always accompanied by a reduction which is the gain of electrons by an element.
3. Which rundown incorporates three sorts of synthetic responses?
Three types of chemical reactions are:
(1) condensation, double replacement, and sublimation
(2) condensation, solidification, and synthesis
(3) decomposition, double replacement, and synthesis
4. What kind of chemical reaction absorbs thermal energy?
Endothermic Reactions
Endothermic responses, then again, retain heat and additionally light from their environmental factors. For example, decomposition reactions are generally endothermic. In endothermic responses, items have more enthalpy than reactants. Thus, an endothermic reaction is said to have a positive reaction enthalpy. This means that the energy required to break the bonds in the reactants is greater than the energy released when new bonds form in the products; in other words, the reaction requires energy to proceed.
At the point when water separates into hydrogen and oxygen when water is warmed-over 2000 degrees Celsius, a little part separates into hydrogen and oxygen. For this reaction to take place, considerable heat energy is required, so that the reaction is endothermic.
5. What is a sort of protein that speeds up substance responses?
Catalysts are proteins that catalyze or “quicken” synthetic responses.
Explanation:
“Accelerating”, also known as catalysis, is the process by which the speed of a chemical reaction increases. Proteins that are like the workers of the cell and catalyze chemical reactions are called enzymes. An illustration of a compound is glucosidase, which takes up maltose, a disaccharide, and separates it into two monosaccharides (glucose) a lot quicker than one maltose atom could break into two glucose particles autonomously.
The most important types of chemical reactions are:
Combination or Synthetic reaction
Decomposition reaction
Single replacement reactions
Double replacement reactions
Neutralisation
Hydrolysis
Exothermic Reactions
Endothermic Reaction
Definition of chemical reaction
“Change in the nature and composition of a substance as a result of combination or separation of atoms or molecules is known as chemical reaction.”
Or
“Changes occur in the nature of a substances with the composition or decomposition of the substances is called a chemical reaction.”
Chemical changes
Some of the changes around us are purely physical. When water boils, for example, the liquid water turns into gaseous steam. In winter water freezes to form ice. These are physical changes in which chemical composition of water (H2O) does not change.
On the other hand, if we pass an electric current through water, a mixture of gases are produced. We cannot turn these gases back into liquids. The molecules that make up these gases are no longer molecules. They are mixture of hydrogen (H2) and oxygen (O2). If a small flash of fire is applied to the mixture, it explodes as the gases recombine to produce water. Both of these are chemical changes.
Types of chemical reactions
The most important types of chemical reactions:
1. Synthetic Reaction
In this type of reaction, two or more elements generally unite to form a single compound. Elements may combine with elements or they may combine with compounds. Compounds may also unites with other compounds.
2. Decomposition Reaction
In this type of reaction, a compound is broken down into simpler compounds or into it’s elements.
3. Single Replacement Reactions
In this type of reaction, a chemically more active elements reacts with a compound to replace a less active element in that compound. As a result of this reaction, a new element or a new compound is formed.
4. Double Replacement Reactions
Sometimes two compounds react chemically to form new compounds. This reaction occurs when elements in these compounds exchange places with each other.
5. Neutralisation
Neutralisation is an example of double replacement reactions in which two reactants are acid and base which form salt and water. During this reaction, hydrogen ion or proton from the acid is neutralised by the hydroxide ion from the base to form water molecule (H2O).
6. Hydrolysis
Hydrolysis is also an example of double decomposition reaction in which one of the reactant is water. When the hydrogen ion and hydroxide ion of water molecule combine with the ions of weak acids or weak bases to give basic or acidic solution, then hydrolyzation of salts take place and the process is known as hydrolysis.
7. Exothermic Reactions
An exothermic reaction is that in which heat is evolved. Or simply the reaction which release heat or other forms of energy.
When hydrochloric acid (HCl) and sodium hydroxide are mixed they react to form water and sodium chloride with release of heat energy.
9. Endothermic Reaction
An endothermic reaction is that which requires continuous source of energy, usually heat to keep it going. Decomposition of water into oxygen and hydrogen is an endothermic reaction. Formation of ‘red oxide’ of ‘lead’ after heating of ‘lead’ is also an endothermic reaction.
When two or more than two elements called reactants join together in a chemical way to make entirely new different thing called products. This process is called chemical reaction.
Types of chemical reaction
Chemical reactions may be endothermic or exothermic.
Exothermic Reactions are those reactions during which heat is evolved like burning of coal.
Endothermic Reactions are those reactions during which heat is absorbed or those reactions which need heat to kick start the reaction like cooking of food.

Cover your hands and wear safety goggles in a lab.
Conclusion
Two or more elements join to make a new compound this process is called chemical reaction these chemical reactions may be endothermic or exothermic on the basis of heat evolution or absorption.
A chemical reaction is a process of transformation of one set of substances (the reactants) into another (the products). Chemical reactions occur when bonds between broken or formed. The substances on which chemical reaction takes place are reactants and the substances that are formed at the end of a chemical reaction are called the products.
Types of Chemical Reactions
Chemical reactions are of four basic types. These types of chemical reactions have been explained with examples below:
** 1. Combination Reactions**
Combination reaction which is also known as a synthesis reaction, is a reaction in which two or more substances combine to form a single new substance.* Combination reactions can also be called synthesis reactions .The general form of a combination reaction is:
A+B→AB
For example two elements combining to form a compound e.g sodium metal reacts with chlorine gas to product solid sodium chloride
2. Decomposition reaction
A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances. The general form of a decomposition reaction is:
AB→A+B
For example calcium carbonate decomposes into calcium oxide and carbon dioxide.
CaCO3(s)→CaO(s)+CO2(g)
3. Displacement reaction
Displacement reaction is a reaction in which one element replaces a similar element in a compound. The general form of a displacement (also called single-displacement) reaction is:
A+BC→AC+B
In this general reaction, element A is a metal and replaces element B also a metal, in the compound. Similarly a nonmetal can also replace another nonmetal in a compound, and the general equation becomes:
Y+XZ→XY+Z
in this reaction Y is a nonmetal that replaces the nonmetal Z in the compound with X.
Example of displacement reaction: Magnesium metal reacts with copper nitrate solution to give magnesium nitrate and copper metal.
Mg(s) + Cu(NO3)2 (aq) → Mg(NO3)2 + Cu(s)
Similarly metals react with acids toproduce hydrogen gas. This is also an example of displacement reaction. For example zinc reacts with hydrocholric acid to produce aqueous zinc chloide and hydrochloric acid.
Zn(s) + 2HCl (aq) → ZnCl2(s) + H2(g)
4. Double Displacement Reactions
A double-replacement reaction is a reaction in which exchange take place between the positive and negative ions of two ionic compounds to form two new compounds. The general form of a double-displacement reaction is:
AB+CD→AD+CB
In this reaction, A and C are positively-charged cations, while B and D are negatively-charged anions. Double-replacement reactions generally occur between substances in aqueous solution. In order for a reaction to occur, one of the products is usually a solid precipitate, a gas, or a molecular compound such as water.
A precipitate is formed in a double displacement reaction when the cations from one of the reactants combine with the anions from the other reactant to form an insoluble ionic compound for example when aqueous solutions of potassium iodide and lead (II) nitrate are mixed, the yellow precipitates of lead iodide are formed by following reaction.
2KI(aq)+Pb(NO3)2(aq)→2KNO3(aq)+PbI2(s)

Acid rain occurs when nitrogen oxides or sulfur oxides react with floating water droplets to form acids. The chemical reaction equation for the formation of acid rain from sulfur oxides: SO2 + HOH > H2SO3. The equation for the reaction of acid rain from nitrogen oxides: 2NO2 + HOH > HNO2 + HNO3.
Which is the most common chemical reaction in everyday life?
Plants use a chemical reaction called photosynthesis to convert carbon dioxide and water into food (glucose) and oxygen. It is one of the most common daily chemical reactions, and also one of the most important because it allows plants to produce food for themselves and animals and convert carbon dioxide into oxygen.
Which is an example of an oxidation reaction?
This is an example of an oxidation reaction. Other common examples are copper pitting and silver tarnishing. Here is the chemical equation for iron oxide: Fe + O 2 + H 2O → Fe 2O 3.
What are 5 ways to identify chemical reaction?
A chemical reaction occurs when a substance rearranges itself to form a new substance. You can tell if this has happened by looking at one of the five signs of a chemical change. These changes include color change, temperature change, precipitation, gassing and light emission.
What are the classifications of chemical reactions?
Six types of chemical reactions: synthesis, decomposition, single substitution, double substitution, acid-base, and combustion. Chemical reactions can be summarized by chemical group. These groups are denoted by the letters A, B, C and D. Synthesis and decomposition reactions occur when chemical groups combine or separate.
What type of chemical reactions are these?
5 main types of chemical reactions Synthesis reaction Decomposition reaction Single displacement reaction Displacement reaction Double combustion reaction General form of combustion reaction: Hydrocarbon + Oxygen → Carbon Dioxide + Water.
Types of chemical reactions ppt
Types of Chemical Reactions The PowerPoint presentation covers six types of chemical reactions: synthesis, decomposition, simple exchange (substitution), double exchange (substitution), combustion, and acid-base reactions. The presentation contains simple and understandable diagrams of each reaction,.
What are the general types of chemical reaction?
There are several general types of chemical reactions that can occur depending on what happens as one moves from reactants to products. The most common types of chemical reactions are: Combination. Decomposition. An ordinary journey. Double twist.
You may see physical effects, such as light or heat, that indicate a chemical reaction is taking place. Chemical reactions follow a specific formula, so you can think of each reaction as one of six types of synthesis, combustion, decomposition, simple exchange, double displacement, or acid-base exchange.
What are the types of reaction?
The four main types of reactions are direct combination, analytical reaction, single substitution and double substitution. If you ask about the five most common types of reactions, there are four, then acid-base or redox (depending on who you ask). Remember that a particular chemical reaction can be classified into several categories.
