WebThis demonstration illustrates how to apply the concept of a limiting reactant to the following chemical reaction Mg ( s) + 2 HCl ( aq) ==> H 2 ( g) + MgCl 2 ( aq) One day of lead time is required for this project. Discussion Mg ( s) + 2 HCl ( aq) ==> H 2 ( g) + MgCl 2 ( aq) WebCertain metals like Mg will be oxidized by the hydrogen ions. Note that Mg2+ has a reduction potential of -2.37 V, which is less than H+ 's reduction potential of 0 V. Hence, H2 gas is …
Why does Mn and Mg only react with nitric acid to produce hydrogen …
WebAnswer: The given reaction is Mg (s) + 2HCl (aq) → MgCl 2 (aq) + H 2 (g) The reaction is already balanced for each element. Mass of Mg reacted = 8.35g. Step 1 : Convert 8.35g of Mg to moles. We will convert 8.35g of Mg to 'mol of Mg' using atomic mass of Mg. Atomic mass of Mg = 24.305g/mol WebOct 26, 2015 · Amount of hydrogen to be produced= 44.8/22.4 = 2 moles of H = 2.02 grams of H.
