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?
