four different liquid compounds in flasks at 20 C are represented above. the table below identifies the compounds. flask c shows the most particles in the vapor phase. which of the following is not shown in the model but best helps to explain why flask c must contain pentane
Answers
Answer: C , The strength of the intermolecular forces between the particles in the liquids.
Explanation:
Since we have 4 boiling flasks with liquids that are at a temp of 20⁰C and out of them all, flask C the has most amount of vapour Particles inside of it, because of that we can conclude that it has the weakest Intermolecular force out of the rest of the boiling flasks since at a temp of 20⁰C it has the most amount of gas particles compared with the other flasks, and not to forget the data in the graph shows us the formula and boiling point of flask C that contains pentane and from that data given we can tell that since the boiling point of pentane Is low then it has to have a weak intermolecular forces, causing it to have more vapour Particles than other flasks, proving the answer to be C since showing the strength of the attraction will explain everything we need to know about flask C and why does it have more vapour Particles than the other flasks.
Note:
(A) is not the answer since all the liquid particles in each flask are in random constant motion at a temp of 20⁰C so it does not justify why flask C has more vapour Particles.
(B) is not the answer since showing the relative speeds of each vapour Particle will not justify why flask C has the most amount of gas particles with the respect of its temperature.
(D) is not the correct answer since we already have data given in the graph about the boiling point of pentane and it's formula so showing the particulate representation is useless.
The best explanation is the strength of intermolecular force between the particles in a liquid. Thus option C is correct.
What is intermolecular force?Intermolecular force is defined as the attractive and repulsive force that rises between the molecules of a compound. They are electrostatic in nature.
There are basically five type of intermolecular force.
Dipole-Dipole interactionIon Dipole interactionIon induced dipole interactionDipole induced dipole interactionDispersion forceThe first three forces are collectively known as Vander wall force.
Thus, the best explanation is the strength of intermolecular force between the particles in a liquid. Thus option C is correct.

Answers
Answer:
yes because on the left side 4 hydrogen in right side 4 hydrogen on the left side 2 oxygen in the right side 2 oxygen
Answer:
The Law of Conservation of Mass states that the mass of the system must remain constant over time as the system's mass cannot change because energy is not created nor destroyed. To tell if a chemical equation meets this law, check to see if the number of atoms is the same on both sides of the chemical equation.

Students in class argue about whether salt (NaCl) or water (H2O) has stronger intramolecular forces. Which argument is BEST?
Question 3 options:
Water because it is a common material and will have stronger intramolecular force.
Water is attracted to salt and salt dissociates, so water has stronger intramolecular forces.
Salt never melted and water has a lower boiling point, so salt has stronger intramolecular forces.
Salt is a solid and water is a liquid, so water has stronger intramolecular forces.
Answers
Since intermolecular forces is stronger in a solid than a liquid, then NaCl has stronger intermolecular forces than H2O.
Intermolecular forces exists between molecules of the same or different kinds. Water has a dipole moment hence it can interact effectively with the ions in NaCl. This leads to an ion dipole interaction that results in the dissolution of NaCl in H2O.
NaCl is a solid and water is a liquid. Since intermolecular forces is stronger in a solid than a liquid, then NaCl has stronger intermolecular forces than H2O.
Hence, the best argument that compares the intermolecular interactions in water and NaCl is; salt is a solid and water is a liquid, so water has stronger intramolecular forces.

if the column of water in the water barometer rose to a height of 39 feet, what would the atmospheric pressure be in mm hg?
Answers
The atmospheric pressure for a column of water barometer that rose to 39 feet is 874 mmHg
From the given information, to determine the atmospheric pressure at which the column of the water barometer rose, we will need to convert the height of the water column to mmHg.
From the dimensional analysis of standard rate conversion, we know that:
1 feet = 12 inches
1 inch = 25.4 mm
1 mmHg = 13.6 mm of water.
∴
[tex]\mathbf{\implies 39 \ feet \ of \ H_2O \times \dfrac{12 \ in ch \ H_2O}{1 \ feet \ H_2O} \times \dfrac{25.4 \ mm \ H_2O}{1 \ inch \ H_2O} \times \dfrac{1 mmHg}{13.6 \ mm \ H_2O}}[/tex]

Answers
Answer:
%Li-6 = 5.996% & %Li-7 = 94.004%
Explanation:
let X₁ = Li-6 & X₂ = Li-7 where Xₙ = mole fraction
X₁ + X₂ = 1 => X₁ = 1 - X₂
6·X₁ + 7·X₂ = 6.94004
=> 6(1 - X₂) + 7·X₂ = 6.94004
=> 6 - 6·X₂ + 7·X₂ = 6.94004
=> 6 + X₂ = 6.94004
X₂ = 6.94004 - 6 = 0.94004 => %X₂ = %Li-7 = 94.004%
X₁ = 1.00000 - 0.94004 = 0.05996 => %X₁ = %Li-6 = 5.996%

Explanation:
We are asked to find the density of a bowling ball. The density of an object is its mass per unit volume. It is calculated by dividing the mass by the volume.
[tex]\rho= \frac{m}{v}[/tex]
The mass of the bowling ball is 3.0 kilograms and the volume is 0.0050 cubic meters.
m= 3.0 kg v= 0.0050 m³Substitute the values into the formula.
[tex]\rho= \frac{3.0 \ kg}{0.0050 \ m^3}[/tex]
Divide.
[tex]\rho= 600 \ kg/m^3[/tex]
The density of the bowling ball is 600 kilograms per cubic meter.

A compound is 2. 00% H by mass, 32. 7% S by mass, and 65. 3% O by mass. What is its empirical formula? The first step is to calculate the mass of each element in a 100-g sample of the compound. We use 100 g because it makes the calculations more straightforward. What is the mass of each element in a 100. 0-g sample of the compound? mass H = g mass S = g mass O = g.
Answers
Answer:
We assume that there is 100g of the compound (because it makes it easier to calculate) and we turn the percentages into grams.
2% of Hydrogen = 2g of H
32.7% of Sulfur = 32.7g of S
65.3% of Oxygen = 65.3g of O
Now we change the mass of these elements to moles by dividing the mass by the molar mass (which is the value of atomic mass on your periodic table)
2g/1.01g = 1.98 mol
32.7g/32.06g = 1.02 mol
65.3g/16g =4.08 mol
divide all these mol values by the smallest mol value, which is 1.02. (Round the values to whole numbers)
1.98/1.02 = 2 (rounded) of Hydrogen
1.02/1.02 = 1 of Sulfur
4.08/1.02 = 4 of Oxygen
