*Any chemical change in a matter which involves its transformation into one or more new substances is called a chemical reaction.

*A chemical equation is the symbolic representation  of chemical reaction using the symbols and the formula of the substances involved in the reaction.

Chemical Reaction vs Chemical Equation:

Chemical reactions and chemical equations are two important concepts in chemistry. However, these two are different from each other. Here are the differences between chemical reaction and chemical equation:

Chemical Reaction:

A chemical reaction refers to the process that involves the conversion of one or more substances into new substances. In other words, it is a process where chemical bonds are broken and new bonds are formed between atoms or molecules to create new compounds.

Chemical Equation:

A chemical equation is a symbolic representation of a chemical reaction. It is a shorthand way of representing the reactants and products involved in a chemical reaction. Chemical equations use chemical symbols and formulas to represent the reactants and products involved in the reaction.

Differences:

The main differences between chemical reaction and chemical equation are:

1. Definition: A chemical reaction is the actual process that occurs during a chemical change, while a chemical equation is a symbolic representation of that process.

2. Explanation: A chemical reaction explains what is happening at the molecular level while a chemical equation is a summary of the reaction.

3. Representation: A chemical reaction can be represented in words or by using diagrams while a chemical equation is always represented using chemical symbols and formulas.

4. Information: A chemical reaction provides more details about the reaction such as the energy changes, reaction rate, and mechanism of the reaction while a chemical equation only provides information about the reactants and products involved in the reaction.

5. Usage: A chemical reaction is used to describe the chemical change while a chemical equation is used to represent the chemical change in a concise and standardized way.

In summary, while the chemical reaction is the process involving the conversion of one substance into another, the chemical equation is the symbolic representation of that process.
