The general format AB+CD→AD+BC represents are replacement reaction.
Step-by-step explanation:
A replacement reaction transpires when elements rearrange positions in compounds. There are two kinds of replacement reactions: single and double.
A double replacement reaction happens when a pair of ionic compounds transactions. This creates a couple of new ionic compounds. A double replacement reaction can be described by the common equation:
AB + CD → AD + CB
AB and CD are the two reactant compounds, and AD and CB are the two product compounds that emerge from the reaction. Through the reaction, the ions B and D switch positions.
