Which reaction below is an example of a decomposition reaction? O 2 KI + Pb(NO3)2→ 2 KNO3 + Pbl2 O 4 NO2 + O2→ 2 N2O5 O C2H2 + CO + H20 → C3H4O2 O Hg(CNO)2 → 2 CO + N2+ Hg
Different type of reactions:
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.
c) single displacement reaction:
Single displacement reaction occurs when one of the element displaces the another element from its compound.
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.
f) Decomposition reaction:
Decomposition reaction occurs when large or complex compound break down into simpler compounds or elements
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).
h) combination reaction :
Combination reaction is a reaction in which 2 or more reactant combine to form a single product.
