Chemical reaction:

The reaction in which two or more substances react to form a new product with new properties is called a chemical reaction. For example, in respiration, we inhale oxygen, which reacts with glucose and produces carbon dioxide, water, and energy.

Types of the chemical reactions:

Based on the product formed, changes that occurred, and reactants involved, chemical reactions are classified as combustion, decomposition, displacement, double displacement reaction, exothermic, and endothermic reactions.

In this experiment, we are studying the combination reaction.

Combination reaction:

When two or more reactants react together chemically to form a single product, the reaction is called a combination reaction. The reactants can be two elements, an element and a compound, or two compounds.

Combination reactions are also known as synthesis reactions because, in these reactions, new substances are synthesized.

Combination reaction with two elements:

Most combination reactions are exothermic.

Combination reactions involve the formation of new bonds, and this process releases a large amount of energy in the form of heat.
