The correct Answer is:
To analyze the given assertion and reason, we will break down the concepts of compounds and mixtures, specifically in relation to 22 carat gold. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "22 carat gold is a compound." - To evaluate this, we need to understand what 22 carat gold is. 2. **Definition of 22 Carat Gold**: - 22 carat gold is an alloy, which means it is a mixture of gold and other metals (usually copper or silver). It contains 91.67% gold and 8.33% other metals. - Since it is composed of different metals that are not chemically bonded together, it is not a compound. 3. **Understanding the Reason**: - The reason states that "a compound has a fixed composition of the elements present in it." - This statement is true. A compound is defined as a substance formed when two or more elements are chemically bonded together in a fixed ratio. 4. **Evaluating the Assertion and Reason**: - Since the assertion is incorrect (22 carat gold is not a compound, but a mixture), and the reason is correct (compounds do have a fixed composition), we conclude that the assertion is false while the reason is true. 5. **Conclusion**: - The correct answer is that the assertion is false, and the reason is true. ### Final Answer: - The assertion "22 carat gold is a compound" is **false**. - The reason "a compound has fixed composition of the elements present in it" is **true**.
