A sample of 2.4 g of Magnesium (Mg, atomic mass ≈ 24 g/mol) is reacted with 100 mL of 1.0 M Hydrochloric Acid (HCl). The balanced equation is Mg(s) + 2HCl(aq) rightarrow MgCl_2(aq) + H_2(g).
Which species is the limiting reagent?
- Hydrochloric Acid (HCl)
- Neither, they are in stoichiometric equivalence
- Magnesium (Mg)
- Magnesium Chloride (MgCl_2)
