Types of chemical reactions quiz

🧪 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: $Zn + 2HCl \rightarrow ZnCl_2 + H_2$
• 🔄 Double Displacement Reaction: Ions are exchanged between two reactants, forming two new compounds. Example: $AgNO_3 + NaCl \rightarrow AgCl + NaNO_3$
• ⚡ Combustion Reaction: A rapid reaction between a substance with an oxidant, usually oxygen, to produce heat and light. Example: $CH_4 + 2O_2 \rightarrow CO_2 + 2H_2O$
• ➕ Acid-Base (Neutralization) Reaction: A reaction between an acid and a base, forming a salt and water. Example: $HCl + NaOH \rightarrow NaCl + H_2O$
• 🚀 Redox (Oxidation-Reduction) Reaction: Involves the transfer of electrons between chemical species, where one species is oxidized (loses electrons) and another is reduced (gains electrons).
