Meaning of Reaction

What is Reaction:

Reaction refers to the action that is generated as a result of a stimulus, or the response of a specific action.

Reaction is also understood to be that action of resistance that opposes something, such as "Ana reacted calmly even when Pedro made fun of her comment."

The reaction can happen continuously and originate a chain of reactions to some situation, for example, "Everyone reacted scared when they saw the explosion in the distance."

The word reaction derives from Latin and is composed of the prefix re- which means "backwards" and actio, this last word comes from the verb agere, synonym of "to do", and of the suffix -uncle, which indicates "action" and "effect."

The term reaction can be used in various contexts depending on the situation to be expressed, especially in the area of ​​science.

Reaction in art

In the field of art, the term reaction is used in order to know what the public's opinion is and if the proposed goal was achieved in the projection of a film, theatrical performance, concert, exhibition of paintings or photographs, among others. "When I heard her sing my reaction was to cry with emotion."

Chemical reaction

It is the chemical process in which two or more substances, called reactants, are transformed into another substance different from the initial one by the action of an energy factor. For example, the formation of iron oxide occurs when oxygen in the air reacts with iron.

Exothermic reaction

It is a chemical reaction that releases energy, such as combustion.

Endothermic reaction

It is the chemical reaction that absorbs energy in the form of heat, however, in these reactions the energy of the product is greater than the energy of the reactants. Photosynthesis is an example: plants absorb energy from the sun and transform it into oxygen.

Synthesis reaction

The synthesis or composition reaction is a chemical reaction in which two simple substances, or reactants, combine and create a new substance or more complex product. For example, combining basic oxide with water generates the hydroxide.

Decomposition reaction

Chemical reaction in which two or more simple substances can be obtained from a reagent. There are thermal, catalytic and electrolytic decomposition reactions. For example, sodium carbonate in high temperature decomposes into sodium oxide and carbon dioxide.

Neutralization reaction

Chemical reaction that occurs between an acid and a base that allows determining the concentration of substances in the solution.

Combustion reaction

It is based on the fast exothermic type reaction that originates from a mixture of combustible substances with oxygen. It is characterized by forming a hot flame that emits light during contact with the fuel. For example, sulfur dioxide can arise from these reactions.

Maillard reaction

It is a set of chemical reactions that occur between proteins and reducing sugars. For example, when a protein such as chicken is cooked in the oven, it caramelizes and turns brown on the outside, as part of the reaction of its molecules that also add flavor and aroma to food.

Reversible reaction

The chemical reaction that happens both ways. That is, after the products of the first reaction are formed, they re-form the original products with a forward and reverse reaction rate, thus reaching chemical equilibrium.
