Fish-liver oil is a good source of vitamin A, whose concentration is measured spectrometrically at a wavelength of 329 nm.

Fish oil usually contains some vitamin A and D. It's important to note that the types of omega-3s found in fish oil have greater health benefits than the omega-3s found in some plant sources.

<h3>What type of vitamin A is in fish liver oil?</h3>

The vitamin A in fish oil is the same as the synthetic vitamin A in most supplements -- retinyl palmitate, so it doesn't matter which you use. Cod liver oil tends to cost more but can provide significant amounts of vitamins D and E as well as omega-3 fatty acids (EPA and DHA).

<h3>What are the vitamin concentrates found in fish liver oils?</h3>

The fortified product provided daily 130 mg of eicosapentaenoic acid and 200 mg of docosahexaenoic acid (EPA and DHA, two fatty acids in ), small amounts of supplemental vitamin E, folic acid, and vitamin B6, and additional amounts of oleic acid and alpha-linolenic acid.

Calculate the wavelength for the transition from n = 4 to n = 2, and state the name given to the spectroscopic series to which t
finlep [7]

Answer:

The wavelength for the transition from n = 4 to n = 2 is<u> 486nm</u> and the name  name given to the spectroscopic series belongs to <u>The Balmer series.</u>

Explanation

lets calculate -

Rydberg equation-   \frac{1}{\pi } =R(\frac{1}{n_1^2} -\frac{1}{n_2^2})

where ,\pi is wavelength , R is Rydberg constant ( 1.097\times10^7), n_1 and n_2are the quantum numbers of the energy levels. (where n_1=2 , n_2=4)

Now putting the given values in the equation,

                \frac{1}{\pi }=1.097\times10^7\times(\frac{1}{2^2} -\frac{1}{4^2} )=2056875m^-^1

    Wavelength \pi =\frac{1}{2056875}

             =4.86\times10^-^7 = 486nm

<u>    Therefore , the wavelength is 486nm and it belongs to The Balmer series.</u>

Consider the decomposition of a metal oxide to its elements, where M represents a generic metal. M 3 O 4 ( s ) − ⇀ ↽ − 3 M ( s )
Citrus2011 [14]

Answer:

a) ΔGrxn = 6.7 kJ/mol

b) K = 0.066

c) PO2 = 0.16 atm

Explanation:

a) The reaction is:

M₂O₃ = 2M + 3/2O₂

The expression for Gibbs energy is:

ΔGrxn = ∑Gproducts - ∑Greactants

Where

M₂O₃ = -6.7 kJ/mol

M = 0

O₂ = 0

deltaG_{rxn} =((2*0)+(3/2*0))-(1*(-6.7))=6.7kJ/mol

b) To calculate the constant we have the following expression:

lnK=-\frac{deltaG_{rxn} }{RT}

Where

ΔGrxn = 6.7 kJ/mol = 6700 J/mol

T = 298 K

R = 8.314 J/mol K

lnK=-\frac{6700}{8.314*298} =-2.704\\K=0.066

c) The equilibrium pressure of O₂ over M is:

K=P_{O2} ^{3/2} \\P_{O2}=K^{2/3} =0.066^{2/3} =0.16atm
