Chemical Reactions (Advanced)
Chemical reactions occur in situations where substances react with each other and produce another new substances. Balancing of chemical equations and understanding various types of reactions are basic chemistry skills. These concepts help explain how and why reactions take place and how to predict the outcomes of reactions.
⚖️ Balancing Equations
Balanced equations follow the law of conservation of mass – the number of atoms for each element stays the same before and after the reaction.

📌 How to Balance Equations
- 1️⃣ Write the unbalanced equation.
- 2️⃣ Count atoms on both sides.
- 3️⃣ Adjust coefficients until both sides are equal.
Unbalanced: H2 + O2 → H2O
Balanced: 2H2 + O2 → 2H2O
🔬 Types of Chemical Reactions
There are five main types of chemical reactions. Recognizing the pattern helps you understand what products are formed.
➕ Synthesis (Combination)
Two or more substances combine to form a more complex substance.
➖ Decomposition
A compound breaks down into simpler parts.
🔁 Single Replacement
One element replaces another in a compound.
🔄 Double Replacement
Two compounds swap elements and form new compounds.
🔥 Combustion
A substance reacts with oxygen, releasing heat and light.
