Question

How do you balance this thermite reaction: `?Fe_2O_3(s) + ?Al(s) -> ?Fe(s) ?Al_2O_3(s)`?

Answer 1

`"Garbage in must equal garbage out"`

Explanation:

`Fe_2O_3(s) + 2Al(s) rarr 2Fe(s) +Al_2O_3(s)`

FOr every reactant particle, is there a corresponding product particle? See [here for reaction details and a cool video.](http://www.rsc.org/learn-chemistry/resource/res00000724/the-thermite-reaction?cmpid=CMP00005969)
