Answer:
5.88 μM is the concentration of red dye in the sample.
Explanation:
Absorbance is defined s capacity of a substance to absorb a light of a specified wavelength.It is calculated by using Beer-Lambert Law:
A = absorbance
= Molar absorptivity
c = concentration
l = Length of the solution through which light passes
Given, A = 0.468, l = d = 1.00 cm,c = ?
(
)
5.88 μM is the concentration of red dye in the sample.
Answer:
The correct answer is Polar structure. See the explanation below, please.
Explanation:
The water molecule is formed by the union of an oxygen atom (O) to two hydrogen atoms (H), forming at an angle of 105 °, having the negative electron density over the O and positive over the H. The water due to its polarity can interact with other equal molecules, by hydrogen bridge (occurs between the atom of H and an electronegative element, in this case the O). It corresponds to a type of dipole-dipole interaction.
