5 examples of combination reaction

• The type of reaction in which two reactants combine together and yields one product is called a combination reaction.
• It is also called a synthesis reaction.
• The following are 5 equation in which chemical combination reaction occurs:

1. Formation of slaked lime from quick lime

$CaO+H_2O\rightarrow Ca(OH)_2$

2. Burning of coal

$C+O_2\rightarrow CO_2$

3. Formation of water

$2H_2+O_2\rightarrow 2H_2O$

4. Formation of hydrogen peroxide

$H_2O+O_2\rightarrow H_2O_2$

Answer 2

Answer:

Concept:

A direct combination reaction (sometimes referred to as a synthesis reaction[1]) occurs when two or more atoms or compounds (reactants) combine to generate a single chemical (product). Equations of the form X+Y XY (A+B AB) are used to depict such reactions. When two or more elements are joined to form a single product, it is called a combination reaction. To put it another way, a chemical reaction is called a combination reaction when two or more atoms or compounds react to form a single component.

Answer:

Under the right conditions, it's characterised as a chemical reaction between two or more chemicals encompass the entire substance. The production of new bonds is involved in combination reactions, and this process releases a lot of energy in the form of heat. A combination reaction occurs when two or more reactants come together to produce a single result.
