Elemental sulfur occurs as octatomic molecules, Sg. What mass of fluorine gas is needed to react completely with 25.3 g of sulfur to form sulfur hexafluoride? Mass of F2(g): 45.06 gX
Sodium borohydride (NaBH4) is used industrially in many organic syntheses. One way to prepare it is by reacting sodium hydride with gaseous diborane (B2H6). Assuming an 75.1% yield, how many grams of NaBH4 can be prepared by reacting 7.43 g of sodium hydride and 8.16 g of diborane? Calculate the moles of compound in 0.163 g of ammonium iodide. moles When 77.6 g of calcium and 33.0 g of nitrogen gas undergo a reaction that has a 84.8% yield, what...
