C. The gold would float if placed in the mercury.
A. The mercury will change temperature at a much faster rate under the same heating conditions.
Answer:
B.) Adhesion
Explanation:
A.) is incorrect. Viscosity is a measure of internal friction that affects the fluidity of a liquid.
B.) is correct. Adhesion is the ability of water to stick to other substances (which are not water).
C.) is incorrect. Surface tension is the tension created by the bonds of the surface particles.
D.) is incorrect. Density is a ratio that compares mass to volume.
Answer:
The balanced equation for the dissociation of KI is
KI → K⁺ + I⁻
Explanation:
KI is the potassium iodide.
K⁺ comes from the KOH, a strong base, so the cation is the conjugate weak acid and in water it does not react.
I⁻ comes from HI, a strong acid, so the anion is the conjugate weak base and in water it does not react.
K⁻ + H₂O ← KOH + H⁺
I⁻ + H₂O ← HI + OH⁻
That's why the arrow in the reaction is in the opposite direction.
Answer:
It conducts electricity when it is dissolved in water.
Explanation:
It conducts electricity when it is dissolved in water is a property of a substance that is composed of atoms that are held together by ionic bonds.
The equation that best represents the addition of potassium sulfate to water is 
<h3>Dissolution of potassium sulfate in water</h3>
When potassium sulfate is dissolved in water, it dissociates into its cation and anion according to the following equation:
The positive ions are 2 moles of potassium ions while the negative ion is a mole of sulfate ion.
