The ends of three balloons, containing .6 g, 1.2 g, and 2.4 g of magnesium ribbon, are stretched over the mouth of the three flasks. 100mL of Hydrochloric acid solution is added to three flasks. When the magnesium is shook into the flask, it reacts with hydrochloric acid to form hydrogen gas. Explain why the balloons with 1.2 g and 2.4 g Mg inflated to approximately the same volume. Discuss what was the limiting reagent when the 2.4 g Mg was added to the acid?
