I think the awnser would be C. becuase Pure Substances are made of mostly the same material and properties Such as: Nitrogen Gas, Oxygen Gas, Carbon, Iorn, Water, Sugar and Salt.
Answer:
Saponification
Explanation:
When treated with a base such as NaOH, the ester is transformed back to alcohol and the sodium salt of carboxylic acid. Saponification is the name <u>given</u> to the reaction since it is utilized in the production of soap.
<span>Since the oil slick consists of a single layer, then the thickness of the oil slick is 0.488 nm. When we multiply the thickness of the oil slick by the area A, then we should get the volume of the oil slick 0.708 m^3.
We can set up an equation to find the area A.
(A)(0.488 nm) = 0.708 m^3
A = 0.708 m^3 / 0.488 nm
A = 0.708 m^3 / 0.488 X 10^{-9} m
A = (0.708 / 0.488) X 10^9 m^2
A = 1.45 X 10^9 m^2
The area of the oil slick is 1.45 X 10^9 m^2</span>

Two factors determine whether a substance is a solid, a liquid, or
a gas:
<span>
1) The kinetic energies of the particles (atoms, molecules, or ions) that
make up a substance. Kinetic energy tends to keep the particles moving
apart.<span>
'
2) The attractive inter molecular forces between particles that tend to draw
the particles together.</span></span>
