<span>Solids have molecules that are held tightly together in close bonds. (positive bonded to a negative) They can bend or vibrate but still stay bonded together closely. Solids have very little kinetic energy. </span>
<span>Liquids have molecules that are held in looser bonds. They move more freely and more randomly that in a solid. It is common for the bonds to be flexible enough to slide over each other. </span>
<span>Gasses have the loosest bond of any state of matter. The loose bonds allow the molecules to move freely and far apart. A gas has the greatest kinetic energy of any state of matter,</span>
Answer: option D. the ability of a base to react with a soluble metal salt.
Justification:
NaOH is a strong base, which means that in water it will dissociate according to this reaction:
- NaOH(aq) → Na⁺ (aq) + OH⁻ (aq)
On the other hand, CuSO₄ is a soluble ionic salt which in water will dissociate into its ions according to this other reaction:
Hence, in solution, the sodium ion (Na⁺) will react with the metal salt in a double replacement reaction, where the highly reactive sodium ion (Na⁺) will substitute the Cu²⁺ in the CuSO₄ to form the sodium sulfate salt, Na₂SO₄ (water soluble), and the copper(II) hydroxide, Cu(OH)₂ (insoluble).
That is what the given reaction represents:
CuSO₄ (aq) + 2NaOH(aq) → Cu(OH)₂(s) + Na₂SO₄(aq)

soluble metal salt strong base insoluble base solube salt
Hypothesis is the correct answer
