Welcome to our deep dive into the "Classic Definition of Chemical Reaction!"

In this video, we take a detailed journey through one of the most fundamental concepts in chemistry: chemical reactions. Whether you're a student, teacher, or science enthusiast, understanding the classical definition is crucial for building a strong foundation in the subject.

What is a Chemical Reaction?
At its core, a chemical reaction is a process where one or more substances (reactants) are transformed into different substances (products). These changes involve the making and breaking of chemical bonds, resulting in new materials with distinct properties from the originals.

The classical definition — formulated through centuries of observation and experimentation — emphasizes that a chemical reaction is characterized by a permanent chemical change. This change cannot be undone simply by physical means like filtering, evaporating, or freezing.

Key Elements of the Classical Definition:

Substances Involved: At least one new substance must be formed.

Bond Changes: Chemical bonds between atoms are broken and new bonds are formed.

Energy Exchange: Reactions often involve the absorption or release of energy (in the form of heat, light, or sound).

Observable Evidence: Indicators such as color change, temperature change, gas production, or precipitate formation signal that a chemical reaction has occurred.
Examples of Classic Chemical Reactions:

Burning of wood (combustion)

Rusting of iron (oxidation)

Vinegar reacting with baking soda (acid-base reaction)

Formation of curd from milk (biochemical reaction)
Each of these examples showcases how the original materials are chemically altered into something new and distinct.

Historical Background:
The understanding of chemical reactions dates back thousands of years. Early alchemists, without realizing it, were observing chemical
