Hydrogen peroxide is used as a cleaning agent in the treatment of cuts and abrasions for several reasons. It is an oxidizing agent that can directly kill many microorganisms; it decomposes upon contact with blood, releasing elemental oxygen gas (which inhibits the growth of anaerobic microorganisms); and it foams upon contact with blood, which provides a cleansing action. In the laboratory, small quantities of hydrogen peroxide can be prepared by the reaction of an acid on an alkaline earth metal peroxide, such as barium peroxide. BaO₂ (s) + HCl(aq) → H,O2(aq) + BaCl2(aq) What amount of hydrogen peroxide should result when 1.11 g of barium peroxide is treated with 25.5 mL of hydrochloric acid solution containing 0.0273 g of HCl per mL? g H₂0₂
