Limestone (CaCO₃) is the second most abundant mineral onEarth after SiO2. For many uses, it is first decomposed thermallyto quicklime (CaO). MgO is prepared similarly from MgCO₃.(a) At what Tis each decomposition spontaneous? (b) Quicklime reacts with SiO2to form a slag (CaSiO₃), a byproduct of steel-making. In 2003, the total steelmaking capacity of the U.S. steelindustry was 2,370,000 tons per week, but only 84% of this ca-pacity was utilized. If 50. kg of slag is produced per ton of steel,what mass (in kg) of limestone was used to make slag in 2003?

After a flood fills a basement to a depth of 9.0 feet andcompletely saturates the surrounding earth, the ownerbuys an electric pump and quickly pumps the water out ofthe basement. Suddenly, a basement wall collapses, thestructure is severely damaged, and mud oozes in. Explainthis event by estimating the difference between the outside*pressure at the base of the basement walls and the pressureinside the drained basement. Assume that the density ofthe mud is 4.9 g cm-3 . Report the answer both in atmo-spheres and in pounds per square inch.
