- Which of the these statements are qualitative? Which are quantitative? Explain your choice in each case. (a) The atomic mass of carbon is 12.011 (12.011 atomic mass units). (b) Pure aluminum is a silvery-white metal that is nonmagnetic, has a low density, and does not produce sparks when struck. (c) Sodium has a density of 0.968 g/mL. (d) In animals the sodium cation, Na+, is the main extracellular cation and is important for nerve function.arrow_forwardA liquid with a volume of 8.5 mL has a mass of 6.71 g. The liquid is either octane, ethanol, or benzene, the densities of which are 0.702 g/cm3, 0.789 g/cm3, and 0.879 g/cm3, respectively.

If you know that each copper atom (radius = 128 pm) has a mass of 1.055 1022 g (you will learn in Chapter 2 how to find the mass of one atom), how many atoms are there in this cube? What fraction of the cube is filled with atoms? (Or conversely, how much of the lattice is empty space?) Why is there empty space in the lattice? (b) Now look at the smallest, repeating unit of the crystal lattice of copper. Knowing that an edge of this cube is 361.47 pm and the density of copper is 8.960 g/cm3, calculate the number of copper atoms in this smallest, repeating unit.arrow_forwardOne metal object is a cube with edges of 3.00 cm and a mass of 140.4 g.

- A materials engineer has filed for a patent for a new alloy to be used in golf club heads. The composition by mass ranges from 25 to 31% manganese, 6.3 to 7.8% aluminum, 0.65 to 0.85% carbon, and 5.5 to 9.0% chromium, with the remainder being iron. What are the maximum and minimum percentages of iron possible in this alloy? Use Figure 2.12 to snake a prediction about how the density of this alloy would compare with that of iron; justify your prediction.arrow_forwardWhich two elements from this list exhibit the greatest similarity in physical and chemical properties? Explain your choice. Mg, Br, Si, Sr.arrow_forwardOn October 21, 1982, the Bureau of the Mint changed the composition of pennies (see Exercise 120). Instead of an alloy of 95% Cu and 5% Zn by mass, a core of 99.2% Zn and 0.8% Cu with a thin shell of copper was adopted. The overall composition of the new penny was 97.6% Zn and 2.4% Cu by mass. Does this account for the difference in mass among die pennies in Exercise 120? Assume the volume of the individual metals that make up each penny can be added together to give the overall volume of the penny, and assume each penny is the same size. (Density of Cu = 8.96 g/cm3; density of Zn = 7.14 g/cm3).arrow_forward
