Question

How do you balance `AlBr_3+K->KBr+Al`?

Answer 1

`"Garbage in must equal garbage out"`.

Explanation:

`AlBr_3(s) + 3K(s) rarr Al(s) + 3KBr(s)`

This is actually a redox reaction; however, it does illustrate the required stoichiometry. The given reaction is certainly balanced with respect to mass and charge.
