Different types of chemical reaction: a) Precipitation reaction: In precipitation reaction an insoluble salt is formed by the reaction between 2 aqueous solution containing soluble salts. b) double displacement reaction: In double displacement reaction the cation and anion of the two compound switch places. In this reaction 2 Compound (reactants) exchange of ions to form 2 new compounds (products). AB + CD -----> AD + CB c) single displacement reaction: Single displacement reaction occurs when one of the element displaces the another element from its compound. P + QR ----> PR + Q d) Redox reaction: In redox reactions oxidation and reduction occurs simultaneously. e) Neutralization reaction: Neutralization reaction also known as acid base reaction. As in this reaction acid and base neutralizes to produce salt and water. Acid + Base ----> salt + Water f) Decomposition reaction: Decomposition reaction occurs when large or complex compound break down into simpler compounds or elements. AB -----> A + B g) combustion reaction: Combustion reaction is a reaction in which the Hydrocarbons react with oxygen gas (O2) to produce carbon dioxide (CO2) and water (H2O). CxHy + O2 -----> CO2 + H2O h) combination reaction: Combination reaction is a reaction in which 2 or more reactant combine to form a single product. A + B ----> ABMatching the reaction with the reaction type: a) LiOH + NaCl → LiCl + NaOH Reaction type: double replacement the above reaction is an example of double displacement reaction as in this reaction exchange of an anions and cations occurs in the two compounds. b) 2C2H2 + 5O2 → 4CO2 + 2H2O Reaction type: combustion the above reaction is an example of combustion reaction as in this reaction C2H2 combines with gaseous oxygen to produce carbon dioxide gas and water vapours. c) 2Ca + O2 → 2CaO Reaction type: combination the above reaction is an example of combination reaction as in this reaction Ca combines with O2 gas to produce CaO. d) Mg + 2AuCl → MgCl2 + 2Au Reaction type: single replacement The above reaction is an example of single replacement reaction as in this reaction Mg replaces Au in AuCl to form MgCl2.Conclusion, a) LiOH + NaCl → LiCl + NaOH Option E. Double replacement b) 2C2H2 + 5O2 → 4CO2 + 2H2O Option A. Combustion c) 2Ca + O2 → 2CaO Option B. Combination d) Mg + 2AuCl → MgCl2 + 2Au Option D. Single replacement
