In the first step, aluminum hydroxide reacts to form alumina and water: 2Al(OH3) (s) -gt; Al2O3 (s) + 3H2) (g)In the second step, alumina and carbon react to form aluminum and carbon dioxide: 2Al2O3 (s) + 3C (s) -gt; 4Al (s) + 3CO2 (g)Write the net chemical equation for the production of aluminum from aluminum hydroxide and carbon.
Just multiply all the coefficients of the first step reaction by 2, and add the two equations2 Al2O3 (s) cancels, since it then appears on both sides of the arrow, leaving: 4 Al(OH)3 (s) + 3 C (s) → 4 Al (s) + 3 H2O (g) + 3 CO2 (g)
