?Hydrobromic acid dissolves solid iron according to the reaction:\(Fe(s) + 2
Chapter 4, Problem 31(choose chapter or problem)
Hydrobromic acid dissolves solid iron according to the reaction:
\(Fe(s) + 2 HBr(aq)¡FeBr2(aq) + H2(g)\mathrm{Fe}(s)+2 \mathrm{HBr}(a q) \longrightarrow \mathrm{FeBr}_{2}(a q)+\mathrm{H}_{2}(g)\)
What mass of HBr (in g) do you need to dissolve a 3.2-g pure iron bar on a padlock? What mass of \(\mathrm{H}_{2}\) would the complete reaction of the iron bar produce?
Text Transcription:
Fe(s) + 2 HBr(aq)¡FeBr2(aq) + H2(g) Fe(s)+2 HBr(aq) longrightarrow FeBr_2(aq)+ H_2(g)
H_2
