underline ( )Mg+underline ( )H2SO4gt underline ( )H2+underline ( )Ag(G)

This is a chemical reaction question. The reaction is between magnesium (Mg) and sulfuric acid (H2SO4). The products of this reaction are hydrogen (H2) and magnesium sulfate (MgSO4). The balanced chemical equation for this reaction is: Mg + H2SO4 -> H2 + MgSO4. This means that one molecule of magnesium reacts with one molecule of sulfuric acid to produce one molecule of hydrogen and one molecule of magnesium sulfate.
