Unformatted text preview: The calculated volume for experiment two, which was for hydrogen, was 29.1 l/mol. It is assumed that there is greater error in experiment two due to the higher difference between the calculated and expected value. This could be due to a number of reasons. The system for collecting gas could have had a leak, which would give result in less gas and increase the value for molar volume. Also there could have been error in measuring the mass and volume of the reactants to produce hydrogen gas. One way of correcting there errors would be to leak test the system and be very careful in measuring and collecting the data. Part 1 reaction: 2FeCl 3 (aq) + H 2 O 2 (aq) 2FeCl 2 (aq) + 2HCl (aq) + O 2 (g) Part 2 reaction: Mg (s) + 2HCL (aq) MgCl 2 (aq) + H 2 (g)...
