Question

6 when as element disklaces another eleme
nt from its compound a
reaction on occurs.​

Answer 1

Explanation:

A single-displacement reaction, is a chemical reaction in which one (or more) element(s) replaces an/other element(s) 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. A and B must be either:

Different metals (hydrogen's behavior as a cation renders it as a metal here), in which case C represents an anion; or

Halogens, in which case C represents a cation.

In either case, when AC and BC are aqueous compounds (which is usually the case), C is a spectator ion.

Answer 2

Answer:

Yes that is true and the displaced element will be below the element which displaced it ( in the reactivity series)
