ANSWER:
Solution 92P
Here, we have to find out the type of each reaction.
Synthesis:Β When two or more molecules combine together to form a new compound is called synthesis.
Decomposition :It is a chemical reaction where a single compound splits into two or more simple substances under suitable conditions.
Single displacement reaction:Β It is a chemical reaction where an element reacts with a compound and takes the place of another element in that compound.
Double displacement reaction: It is a chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants interchange their places, forming two new compounds or products.
(a)Β
It is a Decomposition Β reaction.
