10. Hydrogen peroxide can be prepared by the reaction of barium peroxide with sulfuric acid according to

BaO2(s)+H2SO4(aq)->BaSO4(s)+H2O2(aq)

How many milliliters of 4.25 M H2SO4(aq) are needed to react completely with 58.9 g of BaO2(s)?

Answer 1

✔ Recommended Answer

Answer #1

Moles of BaO2 = 58.9 / 169.33 = 0.348 moles

=> Moles of H2SO4 required = 0.348

=> 0.348 = 4.25 x V

=> V = 0.08185 liters = 81.85 mL

Answer 2

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 action of an acid on an alkaline earth metal...
