Answer 2

Explanation:

A single-displacement reaction, also known as a single-replacement reaction, is a reaction by which one element replaces an/other element in a compound. It can be represented generically as: A + B-C → A-C + B This will most often occur if A is more reactive than B, thus giving a more stable product.
