What do you know about chemical reactions and types?
Chemical reactions types and examples :
Chemical reactions types and examples are listed here briefly by the way you can clear your doubts.
Chemical reactions are defined as the process of breaking bonds of the reactants to produce new materials.
In this process, a change occurs in the properties of the reactants to produce new materials that differ in their physical and chemical properties and in the arrangement of their atoms.
Several types, where the types of these reactions differ according to the nature of the reactants and the processes that occur during the reaction, and in this article we will mention all the types of chemical reactions.
Types of chemical reactions in general:
Types of reactions according to the state of the reactants :
where all the components of this reaction are in one state, that is, they occur within one system, for example liquid and gaseous reactions in which the solvent, and examples of which are the interaction of nitrogen gas with hydrogen gas to form ammonia.
where the components of these reactions are in two phases and not in one phase, and the reaction takes place at the separating surface between the phases.
Types of reactions according to the direction of the reaction :
The direction of these reactions is in one direction only and is not reversible.
this reaction goes in two directions, one front and the other back.
Types of reactions by “reaction rate” speed :
1.Very rapid reactions:
These are ionic reactions that occur in an instant. Examples include the interaction of strong acids with strong bases.
one example is the dissociation of hydrogen iodide.
3.Very slow reactions:
it takes a long time to complete.
Types of reactions depending on heat absorption or heat release :
These are reactions that absorb heat during their reaction and require energy.
They are reactions that produce energy.
The main types of chemical reactions:
Types of reactions according to the nature of the reaction itself are five chemical reactions, which are the main known reactions:
Also called deaf reactions, a two-component union occurs to produce a compound or a compound to produce a new compound.
Examples include the interaction of copper with sulfur to produce hydrogen sulfide.
They are also called simple substitution reactions: they are also called simple exchange reactions, in which one element occurs in the place of another component in a reactive compound to produce a new compound.
Examples include the dissolution of table sugar in the presence of heat into steam and carbon.
in which a complex dissociation occurs into two components or elements.
4.Dual substitution reactions :
substitution of two or more elements occurs in the place of two other elements in the interacting compound.
5.Oxidation and reduction reactions:
Also called oxidation and reaction reactions.
Examples include: 2Mg + O2 ――― →2MgO .
