Problem
Identify the classification of a mixture of sand and salt based on a Venn diagram comparing mixtures and compounds.
Answer
B
Step-by-step solution
- Analyze the Venn Diagram: The Venn diagram shows two main categories: "Mixtures" and "Compounds." These categories are further broken down into characteristics.
- Examine the "Mixtures" Circle (Region B): The characteristics listed for mixtures are "Physically combined," "Variable proportions," and "Components retain properties."
- Examine the "Compounds" Circle (Region D): The characteristics listed for compounds are "Chemically combined," "Fixed proportions," and "Components change properties."
- Examine the Overlapping Region (Region C): This region represents characteristics common to both, such as "Made of elements" and "2 or more components."
- Consider the Scenario: The problem describes mixing sand and salt. Sand and salt are distinct substances that are combined physically. When mixed, they do not chemically react, and their individual properties (like the grittiness of sand and the taste of salt) are retained. The proportions can also vary.
- Classify the Mixture: Based on the characteristics of sand and salt, they fit the description of a "Mixture." Specifically, they are "Physically combined," have "Variable proportions," and the "Components retain properties."
- Locate the Correct Region: The characteristics of a mixture are primarily found in the "Mixtures" circle, which is labeled as region B in the diagram. Therefore, a mixture of sand and salt would be placed in region B.
