In addition‚ stoichiometric measurement is widely used in chemistry‚ because it indicates the proportion of mass in which various substances react. By examining one specific example of stoichiometric determination‚ which is: “Stoichiometry and limiting reacting”‚ we found out the different mass proportions in which substance react. In this case

Twenty years ago‚ super-maximum-security prisons were rare in America. As of 1996‚ over two-thirds of states had "supermax" facilities that collectively housed more than 20‚000 inmates. Based on the present study‚ however‚ as of 2004‚ 44 states had supermax prisons. Designed to hold the most violent and disruptive inmates in single-cell confinement for 23 hours per day‚ often for an indefinite period of time‚ these facilities have been lightning rods for controversy.
