Answer 2

Answer:

A combination reaction is one in which two or more reactants combine to generate a single product.

Explanation:

A reaction in which two or more reactants or compounds react to form a single product is known as a combination reaction.

Let A and B be two reactants. Then a combination reaction can be generally represented as:

A + B → AB

where AB is the product.

Example 1: The formation of calcium hydroxide from calcium oxide and water.

$CaO + H_{2}O$ → $Ca(OH)_{2}$

Example 2: The formation of iron oxide.

$4Fe + 3O_{2}$ → $2Fe_{2} O_{3}$
