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>
Answer:
true
Explanation:
Temperature is a measure of the average kinetic energy of the molecules, so energy would naturally be transferred from the molecules with more kinetic energy to the molecules with less kinetic energy
First, you need to count copper mass in alloy.
Second, you have to make an equation an find x ( the copper mass must be added). The answer is: 13,5g pure copper
Volume. Gases and liquids are typically measured in milliliters (mL) or cubic centimeters (cm^3) - both of which are equivalent (1 mL = 1 cm^3).
In science, a model is a representation of an idea, an object or even a process or a system that is used to describe and explain phenomena that cannot be experienced directly. Models are central to what scientists do, both in their research as well as when communicating their explanations.
So your answer would be
C) Models help scientists visualize things they can’t see.
