Questions & Step-by-Step Solutions

In the reaction 3H2 + N2 → 2NH3, which element is oxidized?
  • Step 1: Identify the reactants and products in the reaction: 3H2 + N2 → 2NH3.
  • Step 2: Determine the oxidation states of each element in the reactants and products.
  • Step 3: In H2, hydrogen (H) has an oxidation state of 0 because it is in its elemental form.
  • Step 4: In NH3, hydrogen (H) has an oxidation state of +1.
  • Step 5: Compare the oxidation states of hydrogen before and after the reaction: it goes from 0 to +1.
  • Step 6: Since the oxidation state of hydrogen increases, hydrogen is oxidized.
