Chemical Reaction A process where one or more substances (reactants) transform into new substances (products) with entirely different properties. Examples: Rusting of iron, digestion of food, respiration, burning of magnesium ribbon, formation of curd. Indicators of a Reaction: Change in state, Change in color, Evolution of a gas, Change in temperature, Formation of a precipitate (solid). 2. Chemical Equation A symbolic representation of a chemical reaction using formulas and symbols. Reactants: Written on the Left-Hand Side (LHS) with a '+' sign. Products: Written on the Right-Hand Side (RHS) with a '+' sign. Arrow ( ): Points from reactants to products, showing the direction. Example: (Magnesium oxide) 3. Balanced Chemical Equation According to the Law of Conservation of Mass, matter can neither be created nor destroyed. Therefore, total mass of reactants must equal total mass of products. Definition: An equation where the number of atoms of each element is equal on both sides. Method of Balancing: Hit and Trial method. Why Balance? To satisfy the Law of Conservation of Mass. 4. Types of Chemical Reactions Combination Two or more reactants form one product. (Slaked lime) Decomposition Single reactant breaks into multiple products. Displacement More reactive element displaces less reactive element. Double Displacement Exchange of ions between two compounds. Types of Decomposition Reactions Thermal Decomposition: Uses heat ( ). Electrolytic Decomposition: Uses electricity ( ). Photolytic Decomposition: Uses light ( ). Energy-Based Reactions Exothermic: Heat is released (Respiration, Burning of natural gas). Endothermic: Heat is absorbed (Photosynthesis, Decomposition reactions). 5. Redox Reactions (Oxidation-Reduction) Oxidation: Gain of oxygen OR Loss of hydrogen. Reduction: Loss of oxygen OR Gain of hydrogen. Redox: Both occur simultaneously. Example: is reduced to (Reduction) is oxidized to (Oxidation) Oxidizing Agent: Reducing Agent: 6. Effects of Oxidation in Daily Life Corrosion: Metals are eaten up gradually by air, moisture, or chemicals. Examples: Rusting of iron (Reddish brown), Green coating on copper, Black coating on silver. Prevention: Painting, Galvanization (zinc coating), Alloying. Rancidity: Oxidation of fats and oils in food, resulting in bad smell and taste. Prevention: Keeping food in airtight containers, Adding antioxidants, Flushing chips bags with Nitrogen gas.
