Complete Summary & Study Guide
📚 Key Terminology Flashcards
🧪 BASIC TERMS
- Chemical Reaction: Process where new substances with new properties are formed
- Reactants: Starting materials that undergo chemical change
- Products: New substances formed as result of chemical reaction
- Chemical Equation: Representation of chemical reaction using symbols and formulas
- Balanced Equation: Equal number of atoms of each element on both sides
⚖️ REACTION TYPES
- Combination: A + B → AB (two or more reactants form one product)
- Decomposition: AB → A + B (one reactant breaks into multiple products)
- Displacement: A + BC → AC + B (more reactive element replaces less reactive)
- Double Displacement: AB + CD → AD + CB (exchange of ions)
🔥 ENERGY TERMS
- Exothermic: Reactions that release energy (combustion, respiration)
- Endothermic: Reactions that absorb energy (photosynthesis, decomposition)
- Oxidation: Addition of oxygen or removal of hydrogen
- Reduction: Addition of hydrogen or removal of oxygen
🛡️ PREVENTION TERMS
- Corrosion: Slow destruction of metals by environmental reaction
- Rancidity: Spoilage of fats and oils due to oxidation
- Galvanization: Coating iron with zinc to prevent rusting
- Antioxidants: Substances that prevent oxidation reactions

🔑 Important Patterns
✅ BALANCING CHECKLIST
- Start with most complex molecule
- Balance metals first, then non-metals
- Leave H and O for last
- Use whole number coefficients only
- Double-check atom count
⚠️ REACTION IDENTIFICATION
- Look for: Number of reactants and products
- Combination: Multiple → Single
- Decomposition: Single → Multiple
- Displacement: Element + Compound → New element + New compound
- Double Displacement: Two compounds exchange ions
