Unveiling Chemical Reactions: Transformations in Matter

Learning objective

Learning Objective

At the end of the lesson, you will understand types of chemical reactions, identify reactants/products, and balance equations.

What do you already know about chemical reactions?

What is a Chemical Reaction?

A chemical reaction involves rearranging atoms to form new substances. It can release or absorb energy.

Types of Chemical Reactions

There are several types, including synthesis, decomposition, single replacement, and double replacement.

Identifying Reactants and Products

Reactants are substances that start a reaction, and products are formed as a result.

Balancing Chemical Equations

Balancing ensures the same number of each type of atom is on both sides of the equation.

Energy Changes in Reactions

Exothermic reactions release energy, while endothermic reactions absorb energy.

Learning Check: Quick Quiz

1. Define a chemical reaction. 2. List two types of reactions. 3. Balance: H2 + O2 → H2O.

Real-World Applications

Chemical reactions are vital in industries like pharmaceuticals, agriculture, and energy production.
