1. Define physical and chemical properties, provide three examples of each, discuss their reversibility, and explain the fundamental differences between them. 2. Density is a physical property of a molecule that's measured as mass per unit volume. (a) Given that density is usually expressed in the units of g/cm3, calculate the density of a cube of plastic that has a mass of 2.331 g and an edge length of 1.500 cm (volume of a cube is V= 13). (b) Draw two liquids in a graduated cylinder on a separate sheet of paper. You won't submit the drawing as part of your answer. Liquid A has a density of 1.004 g/cm3 and Liquid B has a density of 0.6223 g/cm3. Assume they don't mix. Label which liquid is on top and which liquid is on bottom, and then draw the cube where you expect it to be if it's dropped into the graduated cylinder with these two liquids. Explain the location for liquid A, liquid B, and the cube in the graduated cylinder. would
