Unformatted text preview: (III) chloride (FeCl3) acting as a catalyst: 2 H2O2 + FeCl3 -> FeCl3 + 2 H2O + O2 In part two, we mixed a strip of magnesium with 4.5mL of 3M HCl: Mg + 2 HCl -> H2 + MgCl2 The calculated molar volumes at STP ended up relatively close to the expected value, off by only a few digits. However, a snag was encountered with the calculations for hydrogen gas. The volume originally measured was 220mL, opposed to the expected estimate of 70mL. Possible explanations for this error lie within the procedure (flasks not equalized; tubes accidentally moved, causing more water displacement)....
