Olevious Page 13 of 16 Next O 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 upc 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 prepa such as barium peroxide BaO2(s) + HC1(aq) → H2O2(aq) +BaCl2 (aq) What amount of hydrogen peroxide should result when 1.21 g of barium peroxide is treated with 26.5 ml of hydrochloric acid solution containing 0.0275 g of HCl per mL? g H2O2

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
