2. Sоlid zinc, Zn(s), reаcts with аqueоus hydrоchloric аcid, HCl(aq), to form aqueous zinc chloride, ZnCl2(aq), and gaseous hydrogen, H2(g). (9pts) Zn(s)  +  2 HCl(aq)   ⟶   ZnCl2(aq)  +  H2(g) To run this reaction, you want to prepare a dilute HCl solution. You add 5.00 mL of 10.9 M HCl solution into a 250 mL volumetric flask and fill to the etched line with deionized water (in other words, you fill to the 250.0 mL mark). What is the concentration of this dilute HCl solution you just prepared? Show all your work. You add 2.00 g of zinc, Zn(s) (molar mass = 65.39 g/mol), to your dilute HCl solution from part (a). How many moles of Zn is that? Show all your work. The reaction proceeds and you see bubbles forming. Once the bubbling subsides and the reaction is complete, you observe some solids at the bottom of the solution. Which reactant was the limiting reactant? Explain your reasoning.
