The chemical equation for the formation of ammonia is unbalanced.
galben [10]

Answer:

The answer to your question is 2 molecules

Explanation:

Unbalanced chemical reaction

                   H₂(g)   +   N₂(g)   ⇒   NH₃ (g)

         Reactants         Elements          Products

                2                      H                       3

                2                      N                       1

Balanced chemical reaction

                   3H₂(g)   +   N₂(g)   ⇒   2NH₃ (g)

         Reactants         Elements          Products

                6                      H                       6

                2                      N                       2

From the balanced chemical reaction we conclude that when 3 molecules of hydrogen react with one molecule of nitrogen, 2 molecules of ammonia will be formed.

Identify the Lewis acid and Lewis base in each reaction:Fe³⁺ + 2H₂O ⇄ FeOH²⁺ + H₃O⁺
yan [13]

In the given reaction Fe³⁺ + 2H₂O ⇄ FeOH²⁺ + H₃O⁺ Lewis acid is Fe³⁺ and the Lewis base is H₂O.

<h3>What is a Lewis acid and Lewis base?</h3>
  • According to the Lewis theory of acid-base reactions, acids accept pairs of electrons and bases donate pairs of electrons.
  • Any substance like H+ ion, which is capable of accepting a pair of nonbonding electrons or an electron-pair acceptor is known as a Lewis acid.
  • Any substance, like the OH- ion, that is capable of donating a pair of nonbonding electrons or an electron-pair donor is a Lewis base.
  • From the Lewis theory, with no change in the oxidation numbers of any atoms, acids react with bases to share a pair of electrons.
