Question

Which of the following is the general format for a double displacement reaction?

A + BX
AX + B A + B
AB AB
A + B AX + BY
AY + BX

Answer 1

AX + BY → AY + BX

Step-by-step explanation:

In double displacement reaction, the cations and anions of the two compounds switch places and form two new compounds. Exchange of bonds takes place. One of the product usually precipitates.

AX + BY → AY + BX

In this general format, AX and BY compounds react, X and Y exchange places and form different compounds (AY and BX).

Answer 2

This is the general format for a double displacement reaction
A + B = AX + BY
It would be the fourth option.
