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/cm', calculate the density of a cube of plastic that hasa mass of 2.331 g and an edge length of 1.500 cm (volume of a cube is V=P). (b) Draw two liquids im 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/cm' and Liquid B has a density of 0.6223 g/cm?. Assume they don't mix. Label which liquid is on top and which liquid is on bottom, and then draw the cube where 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. you would 3. Three quantum numbers are derived from Schrodinger's equation that describe the probability of finding an electron around a nucleus: the principal quantum number, the angular momentum quantum number, and the magnetic quantum number. Explain each quantum number, including associated shapes, numbers, letters, and values. 4. Write the full electron configuration for phosphorus, atomic symbol P, then draw an orbital box diagram on a separate piece of paper that accounts for all of the electrons in phosphorus. You don't need to include the orbital box diagram as part of your answer. Based on your drawing, explain why phosphorus is either paramagnetic or diamagnetic. 5. Compare and contrast the alkali metals and the alkaline earth metals. Discuss their physical and chemical properties, their magnetic properties, and their electron configurations.
