which observation indicates that a substance is a mixture
Answer (1)
An observation that indicates a substance is a mixture is if you can see different parts or components within it—for example, if it looks like it has more than one type of particle, color, or texture that are not chemically bonded.A mixture contains two or more substances physically combined, so you might notice different parts that can be separated by physical means. Unlike a pure substance, a mixture doesn't have a uniform composition throughout, so observing distinct particles, layers, or colors suggests it is a mixture.
