Question

The extraction of aluminum metal from the aluminum hydroxide in bauxite ore by the Hall-Héroult process is one of the most remarkable success stories of late 19th century practical chemistry, turning aluminum from a rare and precious metal into the cheap commodity it is today. In the first step, aluminum hydroxide reacts to form alumina and water: 2AlOH3(s)→Al2O3(s)+3H2O(g) In the second step, alumina and carbon react to form aluminum and carbon dioxide: 2Al2O3(s)+3C(s)→4Al(s)+3CO2(g) Write the net chemical equation for the production of aluminum from aluminum hydroxide and carbon. Be sure your equation is balanced.

Answer 1

Answer: The net chemical equation for the  production of aluminium from aluminium hydroxide and carbon is $2Sl(OH)_3(s)+3C(s)\rightarrow 4Al(s)+3CO_2(g)+3H_2O(g)$

Explanation:

The given intermediate reactions are:

Step 1:  $2Al(OH)_3(s)\rightarrow Al_2O_3(s)+3H_2O(g)$

Step 2:  $2Al_2O_3(s)+3C(s)\rightarrow 4Al(s)+3CO_2(g)$

By combining these two above equations, we will get the net chemical equation for the production of aluminium from aluminium hydroxide and carbon.

The net chemical equation follows:

$2Sl(OH)_3(s)+3C(s)\rightarrow 4Al(s)+3CO_2(g)+3H_2O(g)$

Hence, the net chemical equation for the  production of aluminium from aluminium hydroxide and carbon is $2Sl(OH)_3(s)+3C(s)\rightarrow 4Al(s)+3CO_2(g)+3H_2O(g)$
