From this experiment, what is the limiting reactant: magnesium or acetic acid? Describe at least two pieces of evidence from the experiment that confirm your claim.

Mg(s) + 2 HC2H3O2(aq) -> Mg(C2H3O2)2(aq) + H2(g)

Experimental Yield: 0.00273 g

theoretical yield: 0.00257 g

percent yield: 107%

2. Suppose you performed this experiment at a higher location where the barometric pressure is (likely) lower than your location. Also suppose that all of your other values are the same as what you obtained for the experiment.

Would doing this experiment where the barometric pressure is lower INCREASE or DECREASE the number of moles of H2 produced in the experiment? What is the chemical (and/or mathematical) explanation for why this is?
