Explanation:
Le Chatelier's principle states that for a long period of time if a system is at equilibrium and it is subjected to change in concentration, temperature, volume or pressure then the system shifts to a new equilibrium.
This change will partly counter acts the applied change.
Therefore, when heat is added to the system then equilibrium will shift to the side where temperature or heat is reduced again.
For example, 
Since heat is added to the system, hence, system will shift to the left side or we can say equilibrium will shift to the backward direction.
Answer:
2.67 M
Explanation:
Molarity, which is the molar concentration of a substance, can be calculated using the formula;
M = n/V
Where;
M = molarity (M)
n = number of moles (mol)
V = volume (Litres)
Based on the provided information in this question, mass of lithium sulfate (Li2SO4) = 734g, volume = 2.5L
Using mole = mass/molar mass
Molar mass of Li2SO4 = 7(2) + 32 + 16(4)
= 14 + 32 + 64
= 110g/mol
Mole = 734/110
Mole (n) = 6.67moles
Molarity = n/V
Molarity = 6.67/2.5
Molarity = 2.668
Molarity of Li2SO4 in the solution is 2.67 M
Answer:
Partition coefficients are:
Chloroform-Water: 18.1
Diethyl ether-Water: 3.97
Benzene-Water: 1.71
You would choose chloroform to extract the compound
Explanation:
Partition coeffcient is defined as the ratio between solubility in g/mL of an organic compound and concentration of the solubility in an aqueous solution.
Solubility of the compound in the solvents is:
Water: 1g / 147.0mL = 6.80x10⁻³g/mL
Chloroform: 1g / 8.10mL = 0.123g/mL
Diethyl ether: 1g / 37.0mL = 0.0270g/mL
Benzene: 1g / 86.0mL = 0.0116g/mL
<h3>Partition coefficients are:</h3><h3>Chloroform-Water: 18.1</h3><h3>Diethyl ether-Water: 3.97</h3><h3>Benzene-Water: 1.71</h3><h3 />
The higher partition coefficient, the best extraction because the compound will have more affinity with this solvent in which the compound has the best solubillity.
Chloroform has the higher partition coefficient because has the higher solubility. That means chloroform is the solvent you would choose to extract the compound from an aqueous solution
Answer: I believe it is artificial selection (not certain though)
Explanation: modern day dogs have been bread an domesticated to be used by humans in ways we see fit.
An electron with greater energy.
I hope this helps :)
