Which of the following is a heterogeneous mixture?

Question

Quizplus · Accepted Answer

A heterogeneous mixture is one that is not uniform throughout, meaning that its composition can vary from one part to another. Muddy river water is an example of a heterogeneous mixture because it contains different particles and sediments that are not uniformly distributed throughout the water. Air is a homogeneous mixture because it is made up of mostly nitrogen, oxygen, and other gases that are uniformly mixed. Sugar dissolved in water is also a homogeneous mixture because the sugar molecules are evenly distributed throughout the water. Brass is not a mixture but is an alloy composed of copper and zinc, so it is not heterogeneous or homogeneous. Table salt (sodium chloride) is a pure substance, so it is not a mixture at all.
