Balancing Chemical Equations
Key Concepts
- Law of Conservation of Mass
- Balanced chemical equations
- Reactants and products
- Coefficients
- Atom counting
- Combustion equations
- Symbol equations
Lesson notes
If balancing equations feels like guesswork, this video gives you a method that turns it into a systematic process. You'll start with the Law of Conservation of Mass, understand why equations must balance, and then work through a series of examples from simple single-step reactions to combustion equations — building confidence and speed as you go.
What You Will Learn
00:54What the Law of Conservation of Mass states and why it requires equations to be balanced.
02:16What coefficients are and how they differ from subscripts when balancing equations.
04:26How to count atoms on each side of an equation to check whether it is balanced.
05:50How to balance a simple equation step by step using the atom-counting method.
10:59How to balance combustion equations where both carbon and hydrogen must be balanced.
12:35How to check a final equation by counting every atom type on both sides and confirming they match.
