Hey there!

3d band can hold as many as 10 electrons, while 4s can bear as many as two electrons.

The maximum number of electrons for this composite band should be 12 electrons.

Hope that helps!

What is matter? What is it made up of?

Julli [10]

A definition of "matter" more fine-scale than the atoms and molecules definition is: matter is made up of what atoms and molecules are made of, meaning anything made of positively charged protons, neutral neutrons, and negatively charged electrons. There are three states of matter, they are: solid, liquid and gas. In extreme environments, other states may be present, such as plasma, Bose-Einstein condensates and neutron stars .

The molar absorptivity for aqueous solutions of phenol at 211 nm is 6.17x103L/mol/cm. Calculate the linear range of phenol conce

Scilla [17]

Explanation:

The given data is as follows.

$\lambda$ = 211 nm, $\sum = 6.17 \times 10^{3} mol/L/cm$

l = 1 cm, 7% < Transmittance < 85%

Suppose the aqueous solution follows Lambert-Beer's law. Therefore,

Absorbance = $-log \frac{\text{Percentage transmittance}}{100}$

Hence, for 7% transmittance the value of absorbance will be as follows.

Absorbance = $-log \frac{7}{100}$

$A_{1}$ = 1.155

For 85% transmittance the value of absorbance will be as follows.

Absorbance = $-log \frac{85}{100}$

$A_{2}$ = 0.07058

According to Lambert-Beer's law.

A = $\sum \times l \times C$

where, A = absorbance

$\sum$ = molar extinction coefficient

C = concentration

Therefore, concentration for 7% absorbance is as follows.

$A_{1} = \sum \times l \times C_{1}$

$C_{1}$ = $\frac{1.155}{6.17 \times 10^{3} \times 1}$

= $0.187 \times 10^{-3} mol/L$

= 0.187 mmol/L

Concentration for 85% absorbance is as follows.

$A_{2} = \sum \times l \times C_{2}$

$C_{2}$ = $\frac{0.07058}{6.17 \times 10^{3} \times 1}$

= $0.01144 \times 10^{-3} mol/L$

= 0.01144 mmol/L

Thus, we can conclude that linear range of phenol concentration is 0.01144 mmol/L to 0.187 mmol/L.
