Answer:
A metal-salt displacement reaction and a metal-acid displacement reaction are both types of displacement reactions, where one metal is replaced by another metal in a compound.
The main difference between these two reactions is the type of compound that the metal is being displaced from. In a metal-salt displacement reaction, the metal is being displaced from a salt compound, which is usually an ionic compound composed of a metal and a non-metal. On the other hand, in a metal-acid displacement reaction, the metal is being displaced from an acid compound, which is usually a solution containing hydrogen ions (H+).
In a metal-salt displacement reaction, the metal that is being displaced needs to be less reactive than the metal that is doing the displacing, while in a metal-acid displacement reaction, the metal that is doing the displacing needs to be more reactive than hydrogen (H+).
Overall, both reactions involve the transfer of electrons from one metal to another, but the type of compound being displaced from is what sets the reactions apart.
