Question
volume of HCl = 25.5ml
density of HCl = 0.0275g/ml
mass of HCl = volume * density
= 25.5*0.0275 = 0.70125g
no of moles of HCl = W/G.M.Wt
= 0.70125/36.5 = 0.0192moles
no of moles of BaO2 = W/G.M.Wt
= 1.48/169.32 = 0.00874 moles
BaO2 + 2HCl -----------------------------> BaCl2 + H2O2
2 moles of HCl react with 1 mole of BaO2
0.0192 moles of HCl react with = 1*0.0192/2 = 0.0096 moles of BaO2 is required.
BaO2 is limiting reactant
1 mole of BaO2 react with HCl to gives 1 mole of H2O2
0.00874 moles of BaO2 react with HCl to gives 0.00874 moles of H2O2
mass of H2O2 = no of moles * gram molar mass of H2O2
= 0.00874*34 = 0.297 g of H2O2
BaO2 + 2HCl -----------------------------> BaCl2 + H2O2
1 moles of BaO2 react with 2 moles of HCl
0.00874 moles of BaO2 react with = 2*0.00874/1 = 0.01748 moles of HCl
HCl is excess reactant
no of moles of excess of HCl = 0.0192-0.01748 = 0.00172moles
The of excess of HCl reamins = no of moles * gram molar mass
= 0.00172*36.5 = 0.06278g >>>>>answer

I got this wrong, help 2/3 points 1 Previous Anowers ZumChem6 3 E.096 Notes Ask Youn peroxide is It is an oxidizing agent that can directly kill many microorganisma; it contact with blood, releasing elemental oxygen gas (which inhibits the growth of anaerobic microorganisms); and it foams upon contact with blood, which provides 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. Ba02(s) 2 HCI(aq) +H20(g)Bac(aq) what amount of hydrogen peroxide should resuit when 1.48 g of barium peroxid e is treated with 25.5 mL of hydrochloric acid solution containing 0.0275 g of HCl per mL? : 297 What mass of which reagent is left unreacted? 0317 HCI Ba02
