what does the following formula represent?

h₂o (l) + h₂o (l) ↔ h₃o⁺ (aq) + oh⁻ (aq)

a combustion reaction
a neutralization reaction.
the autoionization of water.
hydrolysis reaction.

Explanation:

• Combustion reaction: Involves reaction with oxygen to produce heat and usually \(CO_2\) and \(H_2O\). Not relevant here.
• Neutralization reaction: Acid + base \(\to\) salt + water. Not the case here.
• Autoionization of water: \(H_2O\) molecules transfer \(H^+\) to form \(H_3O^+\) and \(OH^-\), which matches the given equation.
• Hydrolysis reaction: Involves reaction of a substance with water to break it down. Not this reaction.

Answer:

The autoionization of water.
