Question 36

### Understanding Mixtures and Compounds: An Analogy **Consider the following scenario to understand the concepts of mixtures and compounds:** **Example 1:** Two boxes contain paper clips of different colors: - The first box contains 10 blue paper clips and 10 red paper clips. - The second box contains the same number of each color of paper clip, but with the difference that each blue paper clip is interlocked with a red paper clip. **Question:** - Which box has contents that would be an analogy for a mixture? - Which box has contents that would be an analogy for a compound? #### Explanation: **First Box (Mixture):** - The 10 blue paper clips and 10 red paper clips are mixed together but not interlocked. This represents a mixture where different substances are combined, but they are not chemically bonded to each other. **Second Box (Compound):** - Each blue paper clip is interlocked with a red paper clip, representing a compound where different elements are chemically bonded together in fixed ratios. ### Classifying Matter: **Consider the following descriptions of matter and categorize them as either an element, compound, or mixture:** **a.** One substance present — **Element** **b.** Two substances present, three elements present — **Compound** **c.** Two substances present, always — **Mixture** The classification can be done as follows: - **Element:** Single type of substance present. - **Compound:** Multiple elements chemically bonded together. - **Mixture:** Different substances physically combined but not chemically bonded.
