Determine the density of atoms on the (111), (100), and (110) planes of nickel.

Question

Determine the density of atoms on the (111), (100), and (110) planes of nickel. Iron undergoes a polymorphic transformation at 912 degreeree C. At a temperature just below 912 degreeree C it has a BCC structure (a = 0.293 nm). and at a temperature just above 912 degreeree C the structure is FCC (a = 0.363 nm). Upon heating a block of iron past 912 degreeree C. does the volume increase or decrease, and by what percent? An x-ray diffractometer recorder chart for an element which has either an FCC or a BCC structure shown diffraction peaks at the following 2 theta values: 31.305 degreeree, 36.266 degreeree , 52.228 degreeree , and 62.119 degreeree . The lambda avelength X of the radiation used was 0.1541 nm. Determine the crystal structure of the element. Determine the lattice constant. Identify the element. 1. A copper wire has a diameter of 0.4 mm and a length of 12 cm. How many atoms of copper does it contain? The density of copper is 8.92 g/cm3. A common aluminum alloy, AI-2024, contains 4.4 wt.% copper, 1.5 wt. % magnesium, and 0.6 wt. % manganese. The balance is aluminum. What is the atomic % of the various elements in this alloy? Determine the weight percent of carbon in the iron carbide Fe3C. Write the electronic configuration of the following elements or ions using both s, p, d, f notation and (noble gas) + s,p,d,f notation: Fe, Si, Cu1+, Cu2+, Mn2+, Ti2+ Determine the direction vectors shown in the unit cubes below. Include the sketches in your solution, and clearity mark the origin you have chosen. What are the Miller indices of the crystallographic planes in the cubes shown below? Include the sketches in your solution, and clearly mark the origin you have chosen. Sketch a(111), (321), and(112) planes in a cubic unit cell. Iron has a BCC structure at room temperature. Determine the theoretical density of Fe (a = 0.287 nm). Determine the inter-planar spacing of the (110), (330), and (220) planes in tungsten.
