Question
this is what I have so far(I think I'm heading the right direction but got stuck in what values do I use to calculate part b so then I can answer part c)
In advance Thank you for your help and if you have time can you check my answer in part a.
Discussion: metals will react with acids in a single replacement redox reaction, in which the Moderately act elemental metal forms metal ions in solution, replacing hydrogen ions which form elemental H to your data sheet and write zinc and for aluminum with Ho 4 A the appropriate equations including state designations, for the reaction of In a pure sample of zinc, one mole of zinc, or 65.4 grams, produces one mole of hydrogen gas By measuring the mass of hydrogen evolved by reactio determine the mass of zinc originally use le of zinc, one mole of zinc, or 65.4 grams, produces one mole of hydrogen gas: By n of a sample of zinc lwith attd one could ass of hydrogen evolVe ImlZa 5:49 A pure sample of aluminum produces 3 moles of hydrogen gas for every 2 moles of aluminum, or s40 g. Again, reaction of acid with a pure sample of aluminum would allow you to calculate the original 155 Exp. 15 - Analysis of Al-Zn AlloyExplanation / Answer
b) NH2 = Fzn*0.0153 + (1-Fzn)*0.0556
Fzn = mass of Zn/mass of alloy
= 1.0 g/2.0g
= 0.5
NH2 = Fzn*0.0153 + (1-Fzn)*0.0556
NH2 = 0.5*0.0153 + 0.5*0.0556
= 0.03545
