Slide 1 - Slide

This item has no instructions

Learning Objective
At the end of the lesson, you will be able to balance chemical equations effectively.

Slide 2 - Slide

Introduce the learning objective and explain its importance in understanding chemical reactions.
What do you already know about balancing chemical equations?

Slide 3 - Mind map

This item has no instructions

Chemical Equations
Chemical equations represent the reactants and products of a chemical reaction using chemical formulas and symbols.

Slide 4 - Slide

Define chemical equations and provide examples to illustrate their usage.
Reactants and Products
Reactants are the substances that undergo a chemical change, while products are the substances formed as a result of the chemical reaction.

Slide 5 - Slide

Explain the concept of reactants and products and their role in chemical equations.
The Law of Conservation of Mass
The law states that mass is neither created nor destroyed in a chemical reaction. Therefore, the number of atoms of each element must be equal on both sides of the equation.

Slide 6 - Slide

Discuss the importance of the Law of Conservation of Mass in balancing chemical equations.
Steps to Balance Equations
1. Identify the unbalanced equation.
2. Count the number of atoms for each element on both sides.
3. Use coefficients to balance the equation.
4. Check if the equation is balanced.

Slide 7 - Slide

Explain the step-by-step process of balancing chemical equations and emphasize the importance of checking for balance.
Example Equation
Unbalanced Equation: H2 + O2 → H2O
Balanced Equation: 2H2 + O2 → 2H2O

Slide 8 - Slide

Provide an example equation and demonstrate how to balance it.
Practice Equations
1. Na + Cl2 → NaCl
