Answer:
Chicken fat is in the shallowest area because, being hydrophobic and lipid content of chicken, it is the lowest density compound in the broth, therefore it rises and does not precipitate. All fats usually float in liquid media because their density is less than that of water.
On the other hand, the gelatin that forms in the boil of the chicken broth is a gelatinous compound that is very nutritionally rich, consisting of denatured proteins that leave the chicken undergoing aqueous coagulation.
Both do not mix and due to the difference in densities, but in order to dissociate it, it is convenient to use emulsifiers or by cryogenic methods where cold is applied and its division is better.
Explanation:
In liquid media such as chicken broth, or any broth, when proteins or foods that contain a large amount of fats and proteins are boiled, the fatty layer will always be the most superficial because it is the one with the lowest density, therefore, that denatured coagulated protein with water it will be the next layer and finally the solids such as bone or cartilage remains would be in the deepest area because they are the ones with the highest density.
Another method to dissociate these products is through enzymatic activity, throwing enzymes into the broth formed.
Answer:
MM = 5,521.54 g/mol
Explanation:
To solve this, we need to use the expression for osmotic pressure which is the following:
π = MRT (1)
Where:
M: Concentration of the solution
R: gas constant (0.082 L atm/ mol K
T: temperature in K
25 °C in Kelvin is: 25 + 273.15 = 298.15 K
Now, we do not have the concentration of the solution, but we do have the mass. and the concentration can be expressed in terms of mass, molar mass and volume:
Concentration (M) is:
M = n/V (2)
and n (moles) is:
n = m/MM (3)
Therefore, if we replace (2) and (3) in (1) we have:
π = mRT/V*MM
Solving for MM we have:
MM = mRT/πV (4)
All we have to do now, is replace the given data and we should get the value of the molar mass:
MM = 6.143 * 0.082 * 298.15 / 0.1 * 0.272
MM = 150.1859 / 0.0272
<em>MM = 5,521.54 g/mol</em>
<em>This is the molar mass.</em>
Answer:
Explanation:If 5.51 g of water needs 645 J of energy to warm then 55.1 g of water needs 6450 J of energy to warm.

Answer:
D)2.0
Explanation:
Avogadro’s number represent the number of the constituent particles which are present in one mole of the substance. It is named after scientist Amedeo Avogadro and is denoted by 
.
Also, it is the number of particles in exactly 12.000 g of isotope carbon 12.
Avogadro constant:-
Thus,
Number of particles as 12 grams of carbon-12 constitutes 1 mole
<u>Twice the number of particles as 12 grams of carbon-12 constitutes 1*2 mole</u>
Thus, moles in the substance = 2.0 moles
