Answer:
A) Decomposition reactions:
Step-by-step explanation:
When single chemical compound break apart to form smaller products reaction is called decomposition reaction.
Decomposition reaction:
It is the reaction in which one reactant is break down into two or more product.
AB → A + B
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
Na + Cl → NaCl
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
Precipitation reaction:
When two solution containing salts are combined produced the precipitate of insoluble salt
