Chemistry: Types of Chemical Reactions

Types of Chemical Reactions

Combustion Reaction

• A combustion reaction is a type of chemical reaction that involves the reaction of a substance with oxygen, resulting in the release of heat and light.
• General equation: Fuel + Oxygen → Products + Heat + Light
• Examples: Burning of gasoline in a car engine, burning of wood in a fire

Decomposition Reaction

• A decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more simpler substances.
• General equation: AB → A + B
• Examples: Decomposition of hydrogen peroxide (H2O2) into water and oxygen, decomposition of calcium carbonate (CaCO3) into calcium oxide and carbon dioxide

Neutralization Reaction

• A neutralization reaction is a type of chemical reaction in which an acid and a base react to form a salt and water.
• General equation: Acid + Base → Salt + Water
• Examples: Reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) to form sodium chloride (NaCl) and water, reaction between sulfuric acid (H2SO4) and calcium hydroxide (Ca(OH)2) to form calcium sulfate and water

Oxidation Reaction

• An oxidation reaction is a type of chemical reaction in which an atom, molecule, or ion loses one or more electrons.
• General equation: A → A+ + e-
• Examples: Rusting of iron, combustion of fuels

Displacement Reaction

• A displacement reaction is a type of chemical reaction in which an element displaces another element from a compound.
• General equation: A + BC → AC + B
• Examples: Reaction between zinc (Zn) and copper sulfate (CuSO4) to form zinc sulfate and copper, reaction between iron (Fe) and copper chloride (CuCl2) to form iron chloride and copper

Double Displacement Reaction

• A double displacement reaction is a type of chemical reaction in which two compounds exchange partners, resulting in the formation of two new compounds.
• General equation: AB + CD → AD + CB
• Examples: Reaction between sodium chloride (NaCl) and silver nitrate (AgNO3) to form sodium nitrate and silver chloride, reaction between calcium carbonate (CaCO3) and hydrochloric acid (HCl) to form calcium chloride and carbon dioxide
