Part of the answer you are looking for may be- Molecules overcome attractions easily and at high temperatures, move faster- (paraphrased from Google) Since the question asked was not provided with the statements as proposed in the original question, I cannot give you an exact answer. I did what i could do, hope this helps!
Answer:
This is the correct option:
HSO4– + H2O → SO42– + H3O+
Explanation:
The hydrogen sulfate or bisulfate ion HSO₄⁻ can act as either an acid or a base in water solution. This is called amphoteric
It can act as an acid, because it release a proton:
HSO₄⁻ + H₂O ⇄ H₃O⁺ + SO₄⁻²
It can act as a base, because it accepts a proton:
HSO₄⁻ + H₂O ⇄ H₂SO₄ + SOH⁻
Space -filling models are also known as Calotte models. These are 3 dimensional models that depict the spatial relationships between atoms.
The space-filling model of water molecule shows the 3 D structure of the water molecule. This model CLEARLY REVEALS THE OXYGEN ATOM WHICH IS LOCATED CENTRALLY WITH TWO HYDROGEN ATOMS IN THE ADJACENT SIDES. THE MODEL ALSO SUGGESTS HOW THE WATER MOLECULES ATTRACT EACH OTHER.
I think the correct answer from the choices listed above is option D. <span>When you measure the boiling point of mercury, you are investigating a physical property. Boiling point is a physical property because it involves only a physical change. In boiling, the phase of the substance is only changed not the substance itself is changed.</span>
