Answer:
B) CH3CH2CH2F
Explanation:
All the other compounds listed among the options are capable of forming hydrogen bonds with water except CH3CH2CH2F.
Recall that hydrogen bonds are formed when hydrogen is directly bonded to a highly electronegative atom such as nitrogen, oxygen, fluorine, sulphur, et cetra.
Such bonds are not present in CH3CH2CH2F, rather fluorine is bonded to carbon to give a halogenoalkane. This compound will display the least solubility in water.
Answer:
<u>Higher than</u>
Explanation:
The boiling point of a solution is a colligative property
Atoms present ∝ Colligative Property <em>(Boiling Point)</em>
Since KCl is a strong electrolyte, it completely dissociates into K⁺ and Cl⁻ ions, which doubles the number of atoms as compared to what was initially added
Now it's competition is very weak, Pure water has nothing else dissolved in it. which means that our solution will have much higher boiling point as compared to Pure Water
The electron configuration shown is as of Argon.
copper, but the actual densest is osmium.
Answer:
60.01 kJ energy to melt 180g of ice, <em><u>assuming my figure for heat of fusion.</u></em>
<em><u>Explanation:</u></em>
Please check the wording of the question. "6,01 kmoland the molar - mass of ice is 18.02 g/mol" is hard to interpret.
<em><u>I'll assume the heat of fusion of ice is 6.01 kJ/mole</u></em>?
180 grams of solid water (ice) is 180g/(18.02 g/mole) or 9.999 moles, rounded to 3 sig figs to 10 moles.
(10 moles H2O)*(6.01 kJ/mole) = 60.01 kJ energy to melt 180g of ice.
