Objective The purpose of this experiment is to identify an unknown proprietary drug using thin-layer chromatography. The unknown’s behavior in thin-layer chromatography will be compared with that of its possible component analgesics. The possible unknowns and their analgesic ingredients will be Anacin (aspirin‚ caffeine)‚ Excedrin (acetaminophen‚ caffeine‚ aspirin)‚ Motrin (ibuprofen)‚ and Tylenol (acetaminophen). Introduction Thin-layer Chromatography(TLC) was the method used to figure out and

This assignment verifies that you understand how shared and exclusive locks work. Suppose that S1‚ S2‚ and S3 are sessions connected concurrently to the same database instance. Suppose further that D1‚ D2‚ and D3 are data objects that can be locked with a shared and exclusive lock. For the ten locking situations below‚ indicate‚ for each session‚ whether it procures the requested lock‚ waits‚ or deadlocks. 1. S1 has a shared lock on D1 and S2 attempts to procure a shared lock on D1. Since s1 has
