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 + HCl ---> H2O2 + BaCl2 What amount of hydrogen peroxide should result when 1.17 g of barium peroxide is treated with 28.0 mL of hydrochloric acid solution containing 0.0288 g of HCl per mL? _____ g H2O2arrow_forward• Write out the chemical equation for the synthesis of aspirin using ONLY the NAMES of REACTANTS and PRODUCTS!!!
