Question

What coefficients balance #Al(OH)_3 -> Al_2O_3 + H_2O#?

Cooper Adams · Accepted Answer

undefined The balanced equation for the reaction Al(OH)3 → Al2O3 + H2O is:

2Al(OH)3 → Al2O3 + 3H2O

Avery Adams · Answer

#2Al(OH)_3 rarr Al_2O_3 + 3H_2O# On the the left side, there are #1Al, 3O, and 3H# originaly and # 2Al, 4O, and 2H#. Since both sides need to have the same amount of each element, both sides need to have #2Al, 6O, and 6H#. This is why there are 3 water molecules, two #Al(OH)_3# molecules, and 1 molecule of #Al_2O_3# to have the equation balanced.

undefined To balance the chemical equation Al(OH)₃ → Al₂O₃ + H₂O, the first step is to count the number of atoms on each side of the equation.

On the left side, we have:
1 atom of aluminum (Al)
3 atoms of oxygen (O)
3 atoms of hydrogen (H)

On the right side, we have:
2 atoms of aluminum (Al)
3 atoms of oxygen (O)
1 atom of hydrogen (H)

To balance the number of atoms of each element, we need to adjust the coefficients (the numbers in front of each compound or element).

Here's the step-by-step process to balance this equation:

1. Start by balancing the more complex or most abundant elements first. In this case, we'll start with oxygen (O).

2. Count the number of oxygen atoms on each side. On the left, we have 3 oxygen atoms, while on the right, we have 3 atoms as well. Since these are already equal, we don't need to make any changes for oxygen.

3. Next, balance the hydrogen (H) atoms. On the left, we have 3 hydrogen atoms, while on the right, we only have 1 hydrogen atom. To balance them, we add a coefficient of 3 in front of H₂O, making the equation: Al(OH)₃ → Al₂O₃ + 3H₂O.

4. Finally, balance the aluminum (Al) atoms. On the left, we have 1 aluminum atom, while on the right, we have 2. To fix this, we add a coefficient of 2 in front of Al(OH)₃, making the final balanced equation: 2Al(OH)₃ → Al₂O₃ + 3H₂O.

So, the coefficients to balance the equation Al(OH)₃ → Al₂O₃ + H₂O are 2, 1, and 3, respectively.
