At the beginning of this day, I would like to share with you wonderful chemical reactions to benefit all of us.

Types of chemical reactions

Chemistry plays an important role in our human life. It is involved in many industries, agriculture and medicine. We have mentioned that chemistry is involved in many industries and these industries: - Plastic industry.

 - Glass industry .

 - Cement industry .

- Manufacture of building materials.

 - Petrochemical production.

 - Oil production.

Chemical reactions are used to produce new substances when adding a chemical to another chemical and with certain conditions for each reaction, the two chemicals will react together and produce a new substance. Note: Not all chemicals can interact with each other.

 Chemistry is a very big world and with the advance of the discovery of new chemical substances and elements, scientists and chemists have discovered the types of chemical reactions we provide to you with explanation and examples

Union reactions or annexation

Read more on the theme of the site: 

  CO2(g) + MgO(s) ―――→ MgCO3(s)
C(S) + O2(g) ―――→ CO2(g)
BAO(s)+ H2O(l) ―――→ BA(OH)2(aq)
2Na(s) + Cl2(g) ―――→ 2NaCl(s)
2Mg(s) +O2(g) ―――→ 2MgO(s)
N2O5(g) + H2O(l) ―――→ 2HNO3(aq)

Must and you derived from previous equations that have been two chemicals to produce one new material reaction as in the following formula

 A + B ―――→ AB

And simple examples of interaction between iron and air to form iron rust is another example of iodine reaction with aluminum is produced

 2Al + 3I2 ―→ 2AlI3

The Federation's interactions are divided into the following sections

A - the union of an element

 with an element where an element is combined with another element to be a new compound, for example the interaction of magnesium with oxygen according to the following chemical equation

  Mg + O2 --- → MgO

Where the equation in the end becomes as follows 2Mg + O2 - → → 2MgO

(C) A composite union with another compound

  A new compound is produced from a combination of two compounds, for example the formation of acids by means of a water union with non-metallic elements

  SO3 + H2O --- → H2SO4

Water union with metal elements to form alkali, examples of this

  CaO + H2O --- → CaO (OH) 2

Decomposition or disintegration reactions

Where it is produced when two or more interaction by taking pure material one, as in the following formula

  A --- → B + C

And examples of what happens from the dissolution of the water when you pass the electric current in the middle of a particular which can be represented in the following equation

  2H2O --- → 2H2 + O2

Exchange Interactions

The meaning of exchange interactions can be clarified by considering the following

 Why are not the three interactions given by disintegration interactions considered? Why can not we consider the three interactions given above as direct union?

After contemplating this, dear student must be assured of a third type of interaction

 The chemical is different from disintegration and union, where an element is interacted with a compound for the production of other ants and compounds

Here is my dear student an example of clarification

 Mg (aq) + HCl (aq) - → MgCl2 (aq) + H2 (g) + energy

Oxidation and reaction reactions

We will give you the following example to illustrate this type of interaction

  Magnesium burns with a sharp, bright flame in oxygen to form white smoke of magnesium oxide according to the following equation

  2Mg + O2 --- → AMG

  The magnesium atom lost two electrons, turning it into a magnet

  While the oxygen atom was acquired in aa molecule

  These two electrons, and thus turned into an O-2, will also be explained in the following two equations

2Mg --- → Mg + 2

+ 2é O2 + 4é --- → 2O-2
