Answer:
Percentage of mass of solute in aqueous phase is 28.57%.
Explanation:
- Fraction of solute in aqueous phase.
= Used volume of aqueous solution
= Used volume of organic solution
D = partition coefficient.
Mass of solute in aqueous phase = 
Therefore, Percentage of mass of solute in aqueous phase is 28.57%.
<span>From left to right:
1) starts at high pH, no buffer zone - strong base being titrated with strong acid
2) starts at low pH, no buffer zone - strong acid being titrated with strong base
3) starts at low pH, shows a buffer zone - weak acid titrated with strong base
4) starts at high pH, shows a buffer zone - weak base titrated with strong acid
5) polyprotic due to two equivalence points

The properties that describe how a material interacts with light are color and reflectivity only.
Both observations use a physical property of matter.
The physical properties of substances are the properties of substances that can be observed without changing the arrangement of atoms in the substance.
The ability of an object to scratch another is known as hardness while the ability to reflect visible light is called reflectivity. Both are physical properties.
The color of a substance results from the interaction of the molecules of the substances with light. Objects have specific colors depending on the wavelength of light absorbed and subsequently emitted by the substance.
Reflectivity deals with the ability of an object to reflect visible light.
Both color and reflectivity describe how a material interacts with light.
