Answer: B

Explanation: Evaporation rate is influenced by the liquid's boiling temperature. A lower boilng point means that converting the liquid to a gas takes less energy because higher temperatures mean higher energy content. Assuming that this relationship holds at room temperature and that all other factors are equal, you should expect that Liquid B will evaporate faster.

Answer: D

Explanation:

Because at temerature at 25 and 50 is

to low for a compound to evaporate as gas because the bioling point is 100.

Are there molecules of sodium chloride within a sodium chloride crystal?
alukav5142 [94]
No, within a crystal like structure or ionic lattice of sodium chloride, there are ions of Na and Cl. Na+ and Cl- respectively that are attracted to each other due to their opposite charges. Many of these ions form a crystal structure.

Two liquids, 1 and 2, are in equilibrium in a u-tube that is open at both ends. the liquids do not mix, and liquid 1 rests on to
Artyom0805 [142]
I believe the density p1 is greater than the density p2 .
Since the liquid are at equilibrium in the the open U-tube, the pressure at which the liquids meet should be the same. That is at the position where they are in contact, the pressure that liquid 1 exerts at that point is the same as the pressure exerted by liquid 2 at the point.

For which of the following molecular formulas is the formula shown in parentheses the correct empirical formula? (a) C12H22O11 (
Elodia [21]

Answer:

C₁₂H₂₂O₁₁ (C₁₂H₂₂O₁₁ ).

Explanation:

The empirical formula is obtained when we divide the molecular formula with a whole number giving the simplest ratio of all the elements (in whole number).

a) C₁₂H₂₂O₁₁ :

There is no number with which we can divide the ratio further to get a simpler formula hence the molecular formula of the given compound is the empirical formula of the compound. Hence it is correct.

(C₁₂H₂₂O₁₁),

(b) C₈H₁₂O₄

The empirical formula can be obtained by dividing the formula with "4"

The empirical formula would be

(C₂H₃O)

(c) H₂O₂

The empirical formula would be (H₁O₁)
