Consider de-oxidation by the addition of ferromanganese (60 percent Mn) to molten steel at 1600°C.The initial oxygen content is 0.04 wt%. It has to be brought down to 0.02 wt%. Calculate the quantity of ferromanganese required per tonne of steel. The manganese content of steel before de- oxidation is O.1 wt%. (MnO) + [Fe] = [Mn] + (FeO) Given: K Mp at 1873 K = 0.4.

By definition, steel can contain up to [ ] percent carbon. It is uncommon to see steels containing more than [ ] percent carbon.
Explain how a “shrink-wrapping" experiment could be performed to encapsulate a Cs* ion in a fullerene. Relate this process to Eulers Law and the concept of closed carbon structures.
