Barium carbonate is the source of barium compounds. It is produced in an aqueous precipitation reaction from barium sulfide and sodium carbonate. (Barium sulfide is a soluble compound obtained by heating the mineral barite, which is barium sulfate, with carbon.) What are the molecular equation and net ionic equation for the precipitation reaction? A solution containing 33.9 g of barium sulfide requires 21.2 g of sodium carbonate to react completely with it, and 15.6 g of sodium sulfide is produced in addition to whatever barium carbonate is obtained. How many grams of barium sulfide are required to produce 5.00 tons of barium carbonate? (One ton equals 2000 pounds.)

Water is to be mored from one large reservoir so another at a higher elevation as indicated in Fig. P 5.116. The loss of available energy associated with 2.5 ft^3 / s being pumped from sections (1) to 2 ) is loss =61 V^2 / 2 ft^2 / s^2, where V is the average velocity of water in the 8 -in. inside-diameter piping involved. Determine the amount of shaft power required.

Materials containing the elements Y, Ba, Cu, and O that are superconductors (electrical resistance equals zero) at temperatures above that of liquid nitrogen were recently discovered. The structures of these materials are based on the perovskite structure. Were they to have the ideal perovskite structure, the superconductor would have the structure shown in part (a) of the following figure. a. What is the formula of this ideal perovskite material? b. How is this structure related to the perovskite structure shown in Exercise 85 ? These materials, however, do not act as superconductors unless they are deficient in oxygen. The structure of the actual superconducting phase appears to be that shown in part (b) of the figure. c. What is the formula of this material?

The Gateway Arch in St. Louis, Missouri, has the shape of a catenary (a U-shaped curve similar to a parabola). It can be approximated by the following model, where x and y are measured in feet. Gateway Arch model: y=-(7)/(1000)(x+300)(x-300) How far apart are the legs of the arch at the base?
