###### Question:

3. Hydrobromic acid dissolves solid iron according to the following reaction:

Fe(s) + 2HBr(aq) ---> FeBr2(aq) + H2(g)

What mass of HBr (in g) would you need to dissolve a 3.2 gram pure iron bar on a padlock?

What mass of H2 would be produced by the complete reaction of the iron bar?
