Question

Define different types of chemical reaction and give examples for each.

Answer 1

Dear student
Some common chemical reactions are :
Combustion Reaction: When two or more reactant combine together to form a different product.
C₁₀H₈ + 12O₂ ---> 10CO₂ + 4 H₂O
​Combination reaction: When two reactants combine to form or synthesize a new compound.
8Fe + S₈ ---.>8FeS
Decomposition reaction: When a compound is decomposed or broken into two different compounds or species.
2 H₂O ---> 2H₂ + O₂
Single displacement reaction: When a metal displaces an element from its compound.
Mg + 2H₂O ---> Mg(OH)₂ + H₂
Double displacement : When both the reacting species displaces each other or exchange their ions.
Pb(NO₃)₂ + 2KI ---> PbI₂ + 2KNO₃
Neutralization(Acid-base ) reaction : When two acid and bases react to form a salt and water.
HCl + NaOH --> NaCl + H₂O
