Amounts in Chemical Reactions

Observe as your instructor demonstrates the reaction of magnesium metal and hydrochloric acid to produce hydrogen gas (magnesium chloride is also produced in solution). Your instructor will use varying amounts of magnesium metal and hydrochloric acid in each flask. These amounts have been measured in moles and are represented in the table below.

Questions

Please answer the questions below.

Record your observations about the relative amounts of hydrogen gas produced in each reaction in the table below.

Did any of the reaction combinations appear to produce roughly the same quantity of hydrogen gas? If so detail which combinations of magnesium metal and hydrochloric gas below.

Did any of the reaction combinations leave unreacted excess magnesium? If so detail which combinations of magnesium metal and hydrochloric gas below.
