Hydrobromic acid (HBr) dissolves solid iron according to the reaction: Fe(s) 2 HBr(aq)-FeBr2(aq) H2(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 H2 can the complete reaction of the iron bar produce? | Numerade

Hydrogen gas and bromine gas react to form hydrogen bromide gas.H2 (g) Br2 (g) → 2 HBr (g) ΔH = 72 kJ/mola) Calculate the heat, in kJ, when 1.92 moles of HBr is formed in this reaction at constant pressure.b) In this reaction, heat is (released/absorbed) and the reaction is (endothermic/exothermic).
