Answer: The energy from sunlight drives the reaction of carbon dioxide and water molecules to produce sugar and oxygen, as seen in the chemical equation for photosynthesis.
Explanation:
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.

The number of protons
for all atoms of mercury will remain the same while different isotopes may have different number of neutrons.
Explanation:
Atoms should have equal numbers of protons and electrons. In our example, an atom of thirty six|chemical element, it should contain thirty six electrons since it contains 36 protons. Electrons are organized around atoms in a very special method.
