1) Epsom salts, a strong laxative used in veterinary medicine, is a hydrate, which means that a certain number of water molcules are include in the solid structure. the formula for Epsom salts can be written as MgSO4? xH2O, where x indicates the number of moles of H2O per mol of MgSO4. when 5.061 g of this hydrate is heated to 250 ºC, all the water of hydration is lost, leaving 2.472 g of MgSO4. What is the value of X?
2) The reaction between potassium superoxide, KO2, and CO2, 4 KO2 + 2 CO2 -----> 2K2CO3 + 3 O2 is used as a source of O2 and absorber of CO2 in self-contained breathing equipment used by used by rescue workers.
