Bulk and surface properties of matter including nanoparticles (chemistry only)
Question
- A. They may be toxic to living organisms.
- B. They are too large to be effective.
- C. They do not react with other substances.
- D. They are expensive to produce.
Answer
The correct option is They may be toxic to living organisms.. This answer is correct because it matches the approved learning objective to (chemistry only) Describe that nanoparticles can be used as catalysts in the subtopic Uses of nanoparticles.
Explanation
The correct option is They may be toxic to living organisms.. They may be toxic to living organisms. is correct because it directly supports the approved learning objective to (chemistry only) Describe that nanoparticles can be used as catalysts. This belongs to the subtopic Uses of nanoparticles within Bulk and surface properties of matter including nanoparticles (chemistry only), so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Uses of nanoparticles.
Common mistake
Misunderstanding Nanoparticle Function
Students often think that nanoparticles are only used for their size and do not understand their catalytic properties.
Emphasize that nanoparticles can provide a larger surface area for reactions, enhancing their effectiveness as catalysts.
