Answer:
Making models
Explanation:
Classifying is the grouping together of items that are alike in some way. Answer: Making models involves creating rep- resentations of complex objects or processes.
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
Noble Gas. Metals have 1 or 2 Valence Electrons. Halogens have 7 Valence Electrons. Semi-Metals can have different amounts.
