Answer: Option (b) is the correct answer.

Explanation:

When a compound contains a strong bond between its combining atoms or molecules then the compound will have a high boiling point.

An ionic bond is a strong bond because it contains strong force of attraction between two oppositely charged atoms.

For example, LiF is an ionic compound in which lithium is $Li^{+}$ ion and fluorine is $F^{-}$ ion.

Therefore, LiF compound will have strong force of attraction.

On the other hand, covalent compounds have weak bond due to sharing of electrons. Hence, they have low boiling point.

For example, $CO_{2}$ , $CCl_{4}$ , and $H_{2}$ etc are covalent compounds.

Thus, we can conclude that LiF substance has the highest boiling point.

Answer: Lithium Fluoride

Explanation: Let’s see,,,
1. Obviously not hydrogen or carbon dioxide because they’re gas at room temp.
2. Lithium Fluoride is an ionic compound which means they have higher intermolecular forces and require more energy to break them, so it probably has a higher boiling point.

Answer:

Check the explanation

Explanation:

Acidipic Acid (which is an essential dicarboxylic acid for manufacturing purposes with about 2. 5 billion kilograms produced per year. It is mainly used for the production of nylon and its related materials.)

Going by the question, since the $H_{2} CrO_{4}$ is comparatively mild oxidizing agent than the $CrO_{3}$ , it only oxidizes the carbon group

What is the vapor pressure of an aqueous solution made up of 60.0g of urea (CH4N2O) in 180g of water? the vapor pressure of wate

djyliett [7]

To get the answer you use the Law of Raoult.

Raoult's law states that the decrease of the vapor pressure of a liquid is proportional to the molar fraction of the solute.

ΔP = Pa * Xa

Here Pa = 0.038 atm

And Xa = N a / (Na + Nb), where Na is number of moles of A and Nb is number of moles of b

Na = mass of urea / molar mass of urea = 60 g / (molar mass of CH4N2O)

molar mass of CH4N2O = 12 g/mol + 4*1g/mol + 2*14 g/mol + 16 g/mol = 60 g/mol

Na = 60 g / 60 g/mol = 1 mol

Nb = mass of water / molar mass of water = 180g / 18g/mol = 10 mol

Xa = 1 mol / (10 mol + 1 mol) = 1/11 =0.09091

ΔP = Pb * Xa = 0.038 atm * 0.09091 = 0.0035 atm

Then, the final vapor pressure of water is Pb - ΔP = 0.038atm - 0.0035atm = 0.035 atm.

Answer: 0.035 atm

With what compound will nh3 experience only dispersion intermolecular forces? with what compound will nh3 experience only disper

Burka [1]

Answer is: ammonia experience only dispersion intermolecular forces with BF₃ (boron trifluoride) because BF₃ is only nonpolar molecule (vectors of dipole moments cansel each other, dipole moment is zero).
The London dispersion force (intermolecular force) is a temporary attractive force between molecules.
