Verified step by step guidance1
Recall the basic classifications of matter: elements, compounds, homogeneous mixtures, and heterogeneous mixtures.
An element is a pure substance consisting of only one type of atom, and a compound is a pure substance made of two or more elements chemically combined in a fixed ratio.
A homogeneous mixture has a uniform composition throughout, meaning you cannot distinguish different parts with the naked eye, while a heterogeneous mixture has visibly different components.
Consider the composition of mouthwash: it contains multiple substances (water, alcohol, flavoring agents, etc.) physically combined but not chemically bonded, and it appears uniform throughout.
Based on this, classify mouthwash as a homogeneous mixture because it is a uniform mixture of different substances without chemical bonding.
