Question

what is the chemical reaction and their characters and their types​

Answer 1

A chemical reaction is a process generally characterized by a chemical change in which the starting materials (reactants) are different from the products. Chemical reactions tend to involve the motion of electrons, leading to the formation and breaking of chemical bonds. There are several different types of chemical reactions and more than one way of classifying them. Here are some common reaction types:

Oxidation-Reduction or Redox Reaction

In a redox reaction, the oxidation numbers of atoms are changed. Redox reactions may involve the transfer of electrons between chemical species.

The reaction that occurs when In which I2 is reduced to I- and S2O32- (thiosulfate anion) is oxidized to S4O62- provides an example of a redox reaction:

2 S2O32−(aq) + I2(aq) → S4O62−(aq) + 2 I−(aq)

Direct Combination or Synthesis Reaction

In a synthesis reaction, two or more chemical species combine to form a more complex product.

A + B → AB

The combination of iron and sulfur to form iron (II) sulfide is an example of a synthesis reaction:

8 Fe + S8 → 8 FeS

Chemical Decomposition or Analysis Reaction

In a decomposition reaction, a compound is broken into smaller chemical species.

AB → A + B

The electrolysis of water into oxygen and hydrogen gas is an example of a decomposition reaction:

2 H2O → 2 H2 + O2
