Cu3Au undergoes a phase transition. At elevated temperatures, it has the structure of Cu, where each position is filled randomly with Cu or gold atoms (i.e. at each position, there is a 1/4 probability that the atom is Au, and a 3/4 probability that the atom is Cu). At lower temperatures, the thermodynamically stable phase is a cubic one with space group Pm3m (#221), with a= 3.74Å. Cu is at (0, 0.5, 0.5) and Au is at (0,0,0).

a.Show unit cells of the ordered version.
b.Compare this structure to that of Cu.
c.Explain why the disordered version is favored at higher temperatures

In python this structure can be represented by a set of tuples, where each tuple has two elements. The following two lines would build the set given above and the print it. >>> L = [(’dog’,’white’), (’cat’,’black’),(’mouse’,’black’)] >>> f = set(L) >>> print(f) {(’cat’, ’black’), (’dog’, ’white’), (’mouse’, ’black’)} In the example, first we store the tuples into a list, and then we create a set with those tuples. There are obviously countless other ways to initialize f and get...

Describe the 4 phases of demographic transition. 2 part question For each phase, compare crude birth rates (CBR) to crude death rates (CDR), and state whether the population is stable, growing, or declining in each. Explain factors that contribute to changes in CBR and CDR between phases.

Iron has an fcc structure at temperatures higher than 913 degree centigrade, and bcc structure below this temperature. At 1148 oC, iron can dissolve maximum of 2.08% of carbon to form steel. However, at temperature lower than 723 oC, iron can only dissolve maximum 0.025% carbon. The atomic radius is 0.129 nm in both structures (don't consider thermal expansion). One of the largest void is located at (0, ½ , 0) for fcc. What is the largest void size in...

A voltaic cell consists of Cu²⁺/Cu and Cd²⁺/Cd half-cells. Each compartment has a volume of 0.500 L with the following initial concentrations: [Cu²⁺] = 1.250 M; [Cd²⁺] = 0.250 M at 25°C. What is the [Cu²⁺] when the voltage has dropped to 0.719 V? (E⁰ for Cu²⁺/Cu = 0.340 V and E⁰ for Cd²⁺/Cd = -0.400 V.)
