Interpretation: Three examples of heterogeneous mixture and three examples of solutions that might be used in everyday life needs to be explained.
Concept Introduction: A mixture consists of two or more than two different elements or compounds. Practically all of the matter in environment consists of mixtures of different substance. For example, soil; it has many forms of components, air; it has mixture of many gases, etc.
Answer to Problem 15A
Three examples of heterogeneous mixture are chocolate cereal, pizza, salad dressing.
Three examples of solution are vinegar, water, vegetable oil, etc.
Explanation of Solution
A non-uniform combination of the two different types of components is known as heterogeneous mixture. In this mixture, more than one phase is present. Three examples of heterogeneous mixture are chocolate cereal, pizza, salad dressing.
A uniform phase of a mixture is termed as homogeneous mixture. In the homogeneous mixture only similar type of substance (elements or compounds) are present in a single phase, and they cannot be separate easily. Solution is another name of Homogeneous mixture. Three examples of solution are vinegar, water, vegetable oil, etc.
Heterogeneous mixture and solution are different from each other.
