In the first step, aluminum hydroxide reacts to form alumina and water: 2 Al(OH)3(s)-Al₂O3(s) + 3 H₂O(g) 11 In the second step, alumina and carbon react to form aluminum and carbon dioxide: 2 AL₂O3(s)+3 C(s)-4 Al(s) + 3 CO₂(9) Write the net chemical equation for the production of aluminum from aluminum hydroxide and carbon.

This problem can be worked with Equations 18-6 on a calculator or with the spreadsheet in Figure 18-5. Transferrin is the iron-transport protein found in blood. It has a molecular mass of 81 000 and carries two Fe³* ions. Desferrioxamine B is a chelator used to 18-A. treat patients with iron overload (Box 11-1). It has a molecular mass of about 650 and can bind one Fe³+. Desferrioxamine can take iron from many sites within the body and is excreted (with its iron) through the kidneys. Molar absorptivities of these compounds (satu- rated with iron) at two wavelengths are given in the table. Both com- pounds are colorless (no visible absorption) in the absence of iron. e(M¯' cm¯') A(nm) Transferrin Desferrioxamine 428 3 540 2 730 470 4 170 2 290 (a) A solution of transferrin exhibits an absorbance of 0.463 at 470 nm in a 1.000-cm cell.
