Examples of characteristics are: composition, color, density, odor, toxicity.
Substances: water, salt (sodium chloride), oxygen, gold, and diamond. Mixtures: air, saltwater, stainless steel, trail mix, and concrete.
Examples of homogeneous mixtures include salt solution, sugar solution, copper II sulfate solution, and metal mixtures called alloys.
Mixtures are combinations of two or more pure substances that retain their individual properties and can be separated by physical means. Unlike pure substances, which have a uniform composition and distinct properties, mixtures can vary in composition and may exhibit different characteristics depending on the proportions of the components. Examples of mixtures include air, saltwater, and salad, where each component remains identifiable and does not chemically change.
Some examples of useful mixtures include air (a mixture of gases), soil (a mixture of organic matter and minerals), and alloys (mixtures of metals). These mixtures have unique properties that make them valuable in various applications ranging from construction to manufacturing.
Examples of heterogeneous mixtures include a fruit salad, a jar of mixed nuts, and a bowl of cereal with milk. These mixtures consist of visibly different components that can be easily separated by physical means.
Homogeneous mixtures: 1) Sugar dissolved in water 2) Air 3) Salt water 4) Vinegar 5) Brass Heterogeneous mixtures: 1) Salad 2) Chex Mix 3) Granite 4) Trail mix 5) Soil
Mixtures: can be separated by physical means
Examples of 5 heterogeneous mixtures are milk and cereal, rocks in water, Pizza, soil, and vinegar and oil. These are mixtures that have separate components.
