O synthesis
Odecomposition
Osingle replacement
O double replacement



Answer :

Final answer:

In Chemistry, High School students learn about single-replacement, decomposition, and double-replacement reactions.


Explanation:

In a single-replacement reaction, an element replaces another element in a compound, represented by the general form A+BC → AC+B. For example, if element A replaces the B in compound BC, it forms a new compound AC and releases element B.

In contrast, a decomposition reaction involves a single substance breaking down to form multiple substances. It is represented by a reaction where a single reactant yields multiple products.

A double-replacement reaction occurs between two ionic compounds in aqueous solution, where anions switch to form new compounds. This reaction results in the formation of a solid precipitate or a gas to drive the reaction.
