Asolid sample of metal is dropped into an acidic solution. bubbles form as the metal is dissolved. what kind of reaction have you likely observed?

Explanation:

A single displacement reaction is defined as the reaction in which only one element of a compound is displaced by another element.

For example,

Therefore, when a metal reacts with an acid then hydrogen atom present in the acid is displaced by the metal atom.

As a result, a salt is formed along with evolution of hydrogen gas.

This reaction is similar to a single displacement type reaction.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
