Given the reaction: 6 CO2 + 6 H20 - C2H1206 + 6 02 What is the total number of moles of water needed to make 2.5 moles of C2H1206?

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
