Question

The generic form A+B -> AB is for a ____ reaction,

and AX + BY -> AY +BX is for a ___ - ___ reaction

Answer 1

The first reaction, A + B --> AB is a combination reaction, where two individual reactants combine to form a single product.

The second reaction, AX + BY --> AY + BX is a double displacement reaction, where the two reactants each have two ions/units, and these are swapped, where the X transfers from A to B, and the Y transfers from B to A.
