Question

Write the net chemical equation for the production of aluminum from aluminum hydroxide and carbon. Be sure your equation is balanced and proper phases:

step 1: 2Al(OH)3 (s) --> Al2O3(s) +3H2O (g)

step 2: 2Al2O3(s)+2C(s) --> 3Al(s)+3CO2(g)

Answer 1

step 1: 2Al(OH)₃ (s) --> Al₂O₃(s) +3H₂O (g)

step 2: 2Al₂O₃(s)+2C(s) --> 3Al(s)+3CO₂(g)
Net chemical equation is

4Al(OH)₃ (s) + 2C(s) --->  3Al(s) + 3CO₂(g) + 6H₂O (l)
Now balancing both sides of the reaction, we get
24Al(OH)₃(s) + 18C(s) ---> 24Al(s) + 18CO₂(g)+ 36H₂O(l)
