Examples of All Types of Chemical Reactions (10th Grade)

🧪 Quick Study Guide

• 🔥 Combination Reaction: Two or more reactants combine to form a single product. Example: $2H_2 + O_2 \rightarrow 2H_2O$
• ⚡ Decomposition Reaction: A single reactant breaks down into two or more products. Example: $CaCO_3 \rightarrow CaO + CO_2$
• 🤝 Single Displacement Reaction: One element replaces another element in a compound. Example: $Zn + CuSO_4 \rightarrow ZnSO_4 + Cu$
• 🔄 Double Displacement Reaction: Two compounds exchange ions or groups of ions to form two new compounds. Example: $AgNO_3 + NaCl \rightarrow AgCl + NaNO_3$
• ☀️ Neutralization Reaction: An acid and a base react to form a salt and water. Example: $HCl + NaOH \rightarrow NaCl + H_2O$
• 🚀 Combustion Reaction: A substance reacts rapidly with oxygen, producing heat and light. Example: $CH_4 + 2O_2 \rightarrow CO_2 + 2H_2O$
• 🌡️ Redox Reaction: A reaction involving both reduction and oxidation processes. Oxidation is loss of electrons, reduction is gain of electrons.
