Ответ:
B) single displacement
Explanation:
The given reaction is single displacement reaction.
Cu + 2AgNO₃ → Cu(NO₃)₂ + 2Ag
Copper displace the silver and react with nitrate to form copper nitrate.
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
While other options are incorrect because,
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.
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AC +BD
