Consider the reaction shown below. In one experiment, 90.0 g of HCl was reacted with 50.0 g of zinc. How many grams of H2 gas can be prepared from this reaction?
2 HCl (aq) + Zn (s) → ZnCl2 (aq) + H2 (g)
Using the given mass of HCl, calculate the mass of H2 formed.
Using the given mass of zinc, calculate the mass of H2 formed.
Compare your answers in a) and b) and determine the limiting reactant and theoretical yield of H2.
Limiting reactant: _______________ Theoretical yield: ________________
