Use the data table inside the front cover of Callister or another source of atomic weights and densities to answer this question. A platinum wire is 0.5 mm in diameter and 10 cm long. How many atoms does it contain? Use the data table inside the from cover of Callister or another source of atomic weights to answer this question. An alloy contains 65 wcight% Ni and 35 weight% Cu. What are the atomic percentages of nickel and copper in this alloy? Do problem 2.3 from Callister. Zinc has five naturally occurring isotopes: 48.63% of 64Zn with an atomic weight of 63.929 amu; 27.90% of 66Zn with an atomic weight of 65.926 amu; 4.10% of 67Zn with an atomic weight of 66.927 amu; 18.75% of 68Zn with an atomic weight of 67.925 amu; and 0.62% of 70Zn with an atomic weight of 69.925 amu. Calculate the average atomic weight of Zn. Do problem 2.15 from Callister. Calculate the force of attraction between a Ca^2+ and an O^2- ion whose centers are separated by a distance of 1.25 nm. Do problem 2.25 from Callister. Compute the %IC of the interatomic bond for each of the following compounds: MgO, GaP, CsF, CdS, and FeO. Do Problem 2.3 FE from Callister. What type(s) of bonding would be expected for bronze (a copper-tin alloy)? Ionic bonding Metallic bonding Covalent bonding with some van dcr Waals bonding van der Waals bonding
