"Mixtures vs. Chemical Changes in Matter"
- A homogeneous mixture is uniform throughout, like saltwater where salt dissolves in water, creating a uniform solution. In contrast, a heterogeneous mixture consists of physically distinct parts, such as immiscible liquids, like saltwater with added salt that doesn't dissolve, resulting in solid and liquid parts.
- A chemical change involves transforming elements or compounds through a chemical reaction, creating new kinds of matter. For example, hydrogen gas reacting with oxygen gas to form water alters the way atoms are attached, changing compounds and creating a new compound.
