Chemistry is the study of matter and its properties. In this unit, we will begin our journey into the world of chemistry by exploring chemical reactions and equations. We will learn how to represent chemical reactions using equations, how to balance them, and the different types of reactions that occur in our daily lives.

### Understanding Chemical Reactions

A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. We will learn to identify the reactants (the substances that undergo change) and the products (the new substances that are formed). We will also explore the characteristics of chemical reactions, such as changes in state, color, temperature, and the evolution of a gas.

A chemical equation is a symbolic representation of a chemical reaction. We will learn how to write chemical equations using the symbols and formulas of the substances involved. We will also learn the importance of balancing chemical equations to satisfy the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.

### Types of Chemical Reactions

Chemical reactions can be classified into different types based on the nature of the changes that occur. We will explore the following types of reactions in detail:

* **Combination Reactions:** Two or more reactants combine to form a single product.
