Answer:
2H₂O (l) ⇄ H₃O⁺ (aq) + OH⁻(aq)
Explanation:
The autoionization of water is defined as a chemical reaction where there is an equilibrium in which two water molecules react producing an hydronium ion and a hydroxide ion. This is also defined as the autoprotolysis of water, and is based on its amphoteric nature.
The substance that can donate protons as well as receive them is defined as amphoteric. In this way, the water behaves amphoteric as it donates a proton as an acid of Brownsted Lowry or if it receives a proton, being a base.
NH₃ + H₂O ⇄ NH₄ + OH⁻ Kb
In this case, water behaves as an acid, it donates the proton to ammonia (a base)
CH₃COOH + H₂O ⇄ CH₃COO⁻ + H₃O⁺ Ka
For this case, water behaves as a base, it recieves the proton from the acetic acid (acid)
Answer:
c Example 1 represents a liquid and Example 2 represents a solid.
Explanation:
Example 1: Young children dancing slowly around one another
The young children dancing slowly around one another can be pictured as the flow of liquid. In liquids, the molecules are held about weakly and they slide on top of each other. They are held by weak attractive forces. This is clear picture of a liquid.
Example 2: Newborn babies sitting in their given spots in a crib
This is clear example of a solid. In a solid the molecules are held about a fixed spot. The attractive forces in liquids is very great and the molecules therein do not move about randomly.
