describe the types of chemical reaction with on example of each
Answers
Answer:
Combination Reaction
A reaction in which two or more reactants combine to form a single product is known as a combination reaction.
Eg.2Na + Cl2 → 2NaCl
Decomposition Reaction
A reaction in which a single compound breaks into two or more simpler compounds is known as a decomposition reaction.
Eg. CaCO3 → CaO + CO2
Displacement Reaction
A chemical reaction in which a more reactive element displaces a less reactive element from its aqueous salt solution.
Eg. Zn + CuSO4 → ZnSO4 + Cu
Double Displacement Reaction
A chemical reaction in which ions gets exchanged between two reactants which form a new compound is called a double displacement reaction.
Eg.BBaCl2 + Na2SO4 → BaSO4 + 2NaCl
Precipitation Reaction
A chemical reaction that involves the formation of an insoluble product (precipitate; solid) is called Precipitation reaction.
Eg. NaCl(aq) + AgNO3(aq) → AgCl(s) + NaNO3(aq)
Explanation:
1 . combination reaction A + B = AB
2 . Decomposition reaction AB = A +B
CL NA = Cl +NA
CH + O2 = CO2 + H2O
