Given the reaction:

Mg (s) + 2 AgNO3 (aq) - - > Mg (NO3) 2 (aq) + 2 Ag (s)

Which type of reaction is represented?

(1) single replacement (3) synthesis

(2) double replacement (4) decomposition

Reaction: Mg (s) + 2 AgNO3 (aq) → Mg (NO3) 2 (aq) + 2 Ag (s)

Which type of reaction is represented?

double replacement

double replacement a bimolecular process involving the exchange of bonds between the two reacting chemical species, which

results in the creation of products with

similar or identical bonding affiliations.

To illustrate, consider two chemical species, AB and CD, which react to give AD and CB:

AB + CD → AD + CB
