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 peroxide, such as barium peroxide. bao2(s) + 2 hcl(aq) h2o2(aq) + bacl2(aq) what amount of hydrogen peroxide should result when 1.49 g of barium peroxide is treated with 25.1 ml of hydrochloric acid solution containing 0.0279 g of hcl per ml? webassign will check your answer for the correct number of significant figures. 0.299 correct: your answer is correct. g what mass of which reagent is left unreacted? webassign will check your answer for the correct number of significant figures. 0.0367 incorrect: your answer is incorrect. g hcl bao2 correct: your answer is correct.

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
