What is the balaced equation for the decomposition of aluminum chloride?

2AlCl3==> 2Al + 3Cl2
if it simply decomposes and nothing else is added.

To balance the equation for the decomposition of aluminum chloride, you need to make sure that the same number of atoms of each element appears on both sides of the equation. Here's how you can balance it:

The given unbalanced equation is:
AlCl3 ==> Al + Cl2

Step 1: Count the number of atoms on both sides of the equation.
- On the left side: 1 Al atom and 3 Cl atoms.
- On the right side: 1 Al atom and 2 Cl atoms.

Step 2: Balance the atoms one by one, starting with the most complex molecule.
- There are 3 Cl atoms on the left side, but only 2 on the right side. To balance the Cl atoms, we need to multiply Cl2 on the right side by 3/2 (1.5).

The balanced equation becomes:
AlCl3 ==> Al + (3/2)Cl2

To avoid using fractions, we can multiply everything in the equation by 2 to get whole numbers:
2AlCl3 ==> 2Al + 3Cl2

Now the equation is balanced, with 2 Al atoms and 2 AlCl3 molecules on both sides, as well as 6 Cl atoms (3 Cl2) on both sides.
