Classifying Chemical Reactions Flashcards

Types of Chemical Reactions

• Synthesis Reaction: Combines two or more reactants to create a single product (e.g., A + B → AB).
• Decomposition Reaction: A single compound breaks down into two or more elements or new compounds (e.g., AB → A + B or ABC → AB + C).
• Single-Replacement Reaction: An atom from one element replaces an atom in a compound (e.g., A + BX → AX + B).
• Double-Replacement Reaction: Involves the exchange of ions between two compounds (e.g., AX + BY → AY + BX).
• Combustion Reaction: Hydrocarbons react with oxygen to produce energy, carbon dioxide, and water.

Chemical Notation

• Chemical Equation: Describes a chemical reaction using symbols and formulas to represent reactants and products.
• Precipitate: A solid that forms when a solution undergoes a chemical reaction, indicating a new substance has been created.
• Coefficient: Indicates the number of molecules or atoms involved in the reaction, placed in front of chemical formulas (e.g., 2H₂O indicates two water molecules).
• Word Equation: Represents reactants and products using words instead of symbols (e.g., hydrogen + oxygen → water).
• Formula Equation: Uses chemical symbols or formulas to depict the reactants and products in a chemical reaction (e.g., 2H₂ + O₂ → 2H₂O).
• Electrolysis: The process of breaking down a substance using an electric current, often used to separate elements from compounds.
