N general, a scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of a phenomenon is called a scientific theory.
Panacetin is a mixture of three components: sucrose, aspirin and tylenol. To determine the arrangement of layers, you must research on the densities of the components. The densities of sucrose, aspirin, and tylenol are 1.59 g/mL, 1.4 g/mL and 1.26 g/mL. The more dense the component, the farther it sinks to the bottom. Thus, the topmost layer is tylenol, followed by aspirin, and the bottom layer is sucrose. <em>Therefore, aspirin is placed in the second layer.</em>
