2Fe(OH)3 → Fe2O3 + 3H2O

There are 2 iron atoms on the left, and 2 iron atoms on the right. There are 6 oxygen atoms on the left, and 6 oxygen atoms on the right. There are 6 hydrogen atoms on the left and 6 hydrogen atoms on the right.

This equation is balanced.

2Al(OH)3→ Al2O3+ 3H2O

There are 2 aluminum atoms on the left, and 2 aluminum atoms on the right. There are 6 oxygen atoms on the left, and 6 oxygen atoms on the right. There are 6 hydrogen atoms on the left and 6 hydrogen atoms on the right.
