Consider this reaction: li3n(s) + 2 h2(g) → linh2(s) + 2 lih(s)a. how many grams of h2do we need to react with 1.5 g of li3n? consider this reaction: li3n(s) + 2 h2(g) → linh2(s) + 2 lih(s)

Silica, sio2, is formed on silicon as an electrically insulating layer for microelectronic devices. silica is formed when silicon is exposed to o2 gas at an elevated temperature. at 900˚c, it takes 90 minutes for the oxygen to diffuse from the surface to form a 0.06 micron (0.06 x 10-6 m) thick layer of sio2 on
