1.In the empirical formula lab this quarter your, Zn was reacted with hydrochloric acid to produce zinc chloride and hydrogen gas as shown below.
Zn (s) + 2 HCl (aq) ?H2 (g) + ZnCl2 (aq)
If 1.71 g of Zn is reacted with 10.76 mL of 3.00 M HCl, how many moles of limiting reactant will be consumed.
atomic masses: Zn = 65.39, H = 1.01, Cl= 35.45
2.f 2.41 moles of Zn reacts with 3.87 moles of HCl at STP, how many L of H2 should be produced?
3.If a reaction is supposed to produce 8.35 grams of product but only produces 6.66 grams of product, what is the percent yield of the reaction?
