​

Answer 1

Some Reactions are given to us , and we need to classify the type of reaction . Firstly let us define the types of reaction given in Question .

$\underline{\underline{\blacksquare\pink{\textsf{ Displacement Reaction:- }}}}$

• The reaction in which a more reactive substance displaces a less reactive substance from its salt solution is called displacement reaction .

$\underline{\underline{\blacksquare\pink{\textsf{ Combination Reaction :- }}}}$

• The reaction in which two or more substances combine to form a single substance is called a combination reaction .

$\underline{\underline{\blacksquare\pink{\textsf{ Decomposition Reaction :- }}}}$

• The the reaction in which single substance decomposes into two or more substance is called a decomposition reaction .

$\underline{\underline{\blacksquare\pink{\textsf{ Double Displacement Reaction :- }}}}$

• The reaction in which compounds react by the exchange of their ions is called a double displacement reaction .

Now from these , above definitions we can classify the Reactions .

$\boxed{\begin{array}{c|c} \sf 1 & \sf Displacement\ Reac^n \\\\\sf 2&\sf Double\ Displacement \ Reaction \\\\\sf 3 &\sf Decomposition \ Reaction \\\\\sf 4 &\sf Combination\ Reaction \\\\\sf 5 & \sf Decomposition\ Reaction \\\\\sf 6 &\sf Combination\ Reaction \\\\\sf 7 &\sf Substitution \ Reaction \\\\\sf 8 &\sf Double\ Displacement\ Reaction \end{array}}$
