Question

types of chemical reaction and name them​

Answer 1

Heya mate, here's your answer

Combination - A combination reaction (also known as a synthesis reaction) is a reaction where two or more elements or compounds (reactants) combine to form a single compound (product).

Such reactions may be represented by equations of the following form:

X + Y → XY.

Decomposition - A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B.

Single displacement - A single-displacement reaction, also known as a single-replacement reaction, is a reaction by which one element replaces an/other element in a compound.

It can be represented generically as:

A + B-C → A-C + B

This will most often occur if A is more reactive than B, thus giving a more stable product.

Double displacement - A double-replacement reaction exchanges the cations (or the anions) of two ionic compounds.

A precipitation reaction is a double-replacement reaction in which one product is a solid precipitate.

Combustion - Combustion reactions always involve molecular oxygen O2. Anytime anything burns , it is a combustion reaction.

Combustion reactions are almost always exothermic

Redox - Redox is a type of chemical reaction in which the oxidation states of atoms are changed.

Redox reactions are characterized by the transfer of electrons between chemical species, most often with one species undergoing oxidation while another species undergoes reduction.

Chemical reactions :

1. Combination reaction

Those reaction in which two or more substances combined to form a single substances are called combination reaction.

For eg. ;

2Mg + O2 ➡ 2MgO

2. Decomposition reaction

Those reaction in which a compound splits up into two or more simpler substances are known as decomposition reaction.

For eg. ;

CaCO3 ➡ CaO + CO2

3. Displacement reaction

Those reactions in which one element take place of another element in a compound, are known as displacement reaction.

For eg .;

CUSO4 + Zn ➡ ZnSO4 + CU

✳✳✳✳✳✳✳✳✳✳✳✳✳✳✳✳✳✳✳✳

4. Double displacement reaction;

Those reactions in which two compounds react by an exchange of Ions to form two new compounds are called double displacement reaction.

For eg. ;

AgnO3 + NaCl ➡ AgCl + NaNO3

5. Redox reaction

Oxidation;

⚫ The addition of oxygen to a substance is called oxidation, the removal of a hydrogen from a substance is called oxidation.

Reduction

The addition of hydrogen to a substance or removal of oxygen from a substance is called reduction.
