Question

Magnesium metal reacts with hydrochloric acid. At the end of the reaction there is a small amount of magnesium left at the bottom of the flask

Answer 1

Answer:

Adding magnesium metal to hydrochloric acid produces hydrogen gas. The magnesium dissolves to form magnesium chloride, MgCl2. Let's write a balanced equation for this reaction.

Answer 2

Magnesium metal is dissolved in HCl in 500mL Florence flasks covered with balloons. The moles of each reagent are changed in each flask in order to demonstrate the limiting reagent concept. In flasks 1 and 2, a small amount of Mg is used and therefore the metal is the limiting reagent.
