Answer:
High
Explanation:
When the unknown compound contains an impurity that is insoluble in cyclohexane, the solute will not dissolve in the solvent (cyclohexane) completely. ∆T of the solution would be smaller than it is supposed to be, when compared to a compound without such insoluble impurity. Molecular weight determination won't be accurate because the molecular weight obtained will be higher as a result of the fact that the mass of the solute would include the actual solute that is changing the temperature and the excess mass of the impurity.
Answer:
Condensing (I think is what you are looking for)
Explanation:
Boiling is liquid -> gas
Condensing is gas -> liquid
Let our basis for answering this item be 1 mol of the given substance. Then, we calculate for the equivalent mass by multiplying the number of moles with the molar mass.
mass = (102.13 g/mol)(1 mol) = 102.13 g of substance
Then, we calculate for the amount of sulfur and fluorine each using the percentage given.
sulfur = (0.6279)(102.13 g) = 64.13 g of sulfur
fluorine = (1 - 0.6279)(102.13 g) = 38 g of fluorine
Then, calculate for the number of moles of the sulfur and fluorine by dividing the calculated mass by the molar mass of each.
moles of sulfur = (64.13 g)(1 mol/32 g) = 2 mols suflur
moles of fluorine = (38 g)(1 mol/19 g) = 2 mols fluorine
The molecular formula of the substance is S₂F₂.
<em>ANSWER: S₂F₂</em>
Definitely, the answer is false. A desiccant is a substance used in order to absorb moisture in the surroundings. It is a hygroscopic material that removes humidity since humidity will aid in the degradation or destruction of materials which are sensitive to moisture.
