Cleaning agents are complex mixtures of chemical components, each with its own specific purpose. The components have very precise measurements to ensure that the cleaning agent has the right properties. What is a cleaning agent an example of? (Hint: it's a type of mixture). Enter your answer

4. \( \mathrm{H}-\mathrm{CH} * \mathrm{O} \) 5. \( \mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{CO}-\mathrm{CH}_{3} \) 6. \( \mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{O}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{CH}_{3} \) 7. \( \mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{NH}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{CH}_{3} \) 8. \( \mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{OH} \) 9. \( \mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{CH} * \mathrm{O} \) 10. \( \mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{CH}-\mathrm{F} \) 11. \( \mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{CO}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{CH}_{3} \)
