DECOMPOSITON REACTIONS
EXPLANATION
The opposite of a combination reaction – a complex molecule breaks down to make simpler ones.
-
-
!!!!!A reaction in which a single compound breaks into two or more simpler compounds is known as a decomposition reaction!!! :!:
The reaction in which a compound decomposes due to heating is known as a thermal decomposition reaction. :red_flag: :check:
EXAMPLES :red_flag: :!:
H2CO3 → H2O + CO2 :check:
H2CO3 (aq.) → CO2 (g) + H2O (l) :check:
2HgO(s)→2Hg(l)+O2(g :check:
SINGLE REPLACEMENT
-
-
DOUBLE REPLACEMENT :
EXPLANATION
A chemical reaction in which ions gets exchanged between two reactants which form a new compound is called a double displacement reaction.

EXAMPLES :pencil2: :!?:
:check: BaCl2(aq) + Na2SO4(aq) → BaSO4(s) + 2 NaCl(aq)
AgNO3 + NaCl → AgCl + NaNO3 :check:
HCl + NaOH → NaCl + H2O :check:
COMBUSTION REACTIONS
EXPLANATION
Oxygen combines with a compound to form carbon dioxide and water. These reactions are exothermic, meaning they give off heat.

EXAMPLES :!: :warning:
Combustion of methane. CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(g) :check:
burning of naphthalene :check:
Combustion of butane :check:
NEUTRALIZATION REACTION
*EXPLANATION
* An acid and a base react with each other. Generally, the product of this reaction is a salt and water.
