Chapter 1, Problem 32GQ
Make a drawing, based on the kinetic-molecular theory and the ideas about atoms and molecules presented in this chapter, of the arrangement of particles in each of the cases listed here. For each case, draw 10 particles of each substance. It is acceptable for your diagram to be two dimensional. Represent each atom as a circle, and distinguish each different kind of atom by shading.
(a) a homogeneous mixture of water vapor and helium gas (which consists of helium atoms)
(b) a heterogeneous mixture consisting of liquid water and solid aluminum; show a region of the sample that includes both substances
(c) a sample of brass (which is a homogeneous solid mixture of copper and zinc)

Copper:(a) Suppose you have a cube of copper metal that is 0.236 cm on a side with a mass of0.1206 g. If you know that each copper atom (radius = 128 pm) has a mass of 1.055 ×10–22 g (you will learn in Chapter 2 how to find the mass of one atom), how manyatoms are there in this cube? What fraction of the cube is filled with atoms? (Orconversely, how much of the lattice is empty space?) Why is there “empty” space in thelattice?(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 8.960g/cm3, calculate the number of copper atoms in this smallest, repeating unit
Container A and Container B were filled completely with chicken powder. The total mass of 1/3 of the chicken powder in Container B and 1/11 of the chicken powder in Container A was 570 g. If 5/11 of the chicken powder in Container A was poured out, the total mass of the chicken powder in both containers became 2.28 kg. How much chicken powder was in
(a) Container A in grams?
(b) Container B in grams?
You are given a hammer, a battery, a bulb, wires and switch.(a) How could you use them to distinguish between samples of metals and non- metals?(b) Asses the usefulness of these tests in distinguishing between metals and non-metals?
