2. DISPLACEMENT REACTION-
A displacement reaction is a type of chemical reaction in
which one element or ion in a compound is replaced by
another element or ion. This type of reaction typically
occurs between a metal and a non-metal.
Example 1-: Zinc + Hydrochloric
acid -
Zinc Chloride + Hydrogen gas
Explanation: In this reaction, zinc
displaces hydrogen to form zinc
chloride and hydrogen gas. This
is a classic example of a single
displacement reaction.
Example 2-: Copper + Silver Nitrate -
Copper Nitrate + Silver
Explanation: In this reaction, copper
displaces silver to form copper
nitrate and silver. This is another
example of a single displacement
reaction.
DOUBLE DISPLACEMENT REACTION-
A double displacement reaction is a type of chemical
reaction in which the cations and anions of two
different compounds switch places, forming two new
compounds.
3. Example 1-: sodium Chloride + Silver
Nitrate - Sodium Nitrate + Silver
Chloride
Explanation: In this reaction, sodium and
silver switch places to form sodium nitrate
and silver chloride. This is an example of a
double displacement reaction.
Example 2-:Barium Chloride + Sodium
Sulfate - Barium Sulfate + Sodium
Chloride
Explanation: In this reaction, barium and
sodium switch places to form barium
sulfate and sodium chloride. This is
another example of a double displacement
reaction.
Decomposion reaction-
A decomposition reaction is a type of chemical
eaction in which a single compound breaks down into
two or more simpler substances.
4. Example 1-:Hydrogen Peroxide - Water
+ Oxygen gas
Explanation: In this reaction, hydrogen
peroxide breaks down into water and
oxygen gas. This is an example of a
decomposition reaction.
Example 2-:Potassium Chlorate - Potassium
Chloride + Oxygen gas
Explanation: In this reaction, potassium
chlorate breaks down into potassium
chloride and oxygen gas. This is another
example of a decomposition reaction.
