Which of the following statements is false? (a) Gases are far less dense than liquids. (b) Gases are far more compressible than liquids. (c) Because liquid water and liquid carbon tetrachloride do not mix, neither do their vapors. (d) The volume occupied by a gas is determined by the volume of its container.

Short Answer

Expert verified
The false statement is (c) "Because liquid water and liquid carbon tetrachloride do not mix, neither do their vapors." The solubility of liquids does not necessarily apply to their vapor phase, so their vapors can still mix even if the liquids do not.

Step by step solution

01

Statement (a) Analysis

Gases are far less dense than liquids. This statement is true because, in gases, particles are more widely spaced compared to liquids. This leads to a much lower density for gases compared to liquids.
02

Statement (b) Analysis

Gases are far more compressible than liquids. This statement is also true. The reason for gases being more compressible than liquids is the relatively large distance between gas particles. When pressure is applied, these particles can be brought closer, allowing a gas to occupy less space (known as compression).
03

Statement (c) Analysis

Because liquid water and liquid carbon tetrachloride do not mix, neither do their vapors. This statement is false. The solubility of liquids does not necessarily apply to their vapor phase. When liquids evaporate, they form gaseous particles that can interact with other gaseous particles. In this case, the fact that liquid water and liquid carbon tetrachloride do not mix does not guarantee that their vapors will not mix.
04

Statement (d) Analysis

The volume occupied by a gas is determined by the volume of its container. This statement is true. According to the gas laws, the volume of a gas depends on the volume of its container since gas particles will uniformly distribute themselves throughout the available space, irrespective of the size of the container. So, the false statement among the given options is (c) "Because liquid water and liquid carbon tetrachloride do not mix, neither do their vapors."

The atmospheric concentration of \(\mathrm{CO}_{2}\) gas is presently 407 ppm (parts per million, by volume; that is, \(407 \mathrm{~L}\) of every $10^{6} \mathrm{~L}\( of the atmosphere are \)\mathrm{CO}_{2}$ ). What is the mole fraction of \(\mathrm{CO}_{2}\) in the atmosphere?

The temperature of a \(5.00-\mathrm{L}\) container of \(\mathrm{N}_{2}\) gas is increased from \(20^{\circ} \mathrm{C}\) to \(250^{\circ} \mathrm{C}\). If the volume is held constant, predict qualitatively how this change affects the following: (a) the average kinetic energy of the molecules; (b) the rootmean- square speed of the molecules; (c) the strength of the impact of an average molecule with the container walls; \(\mathbf{d}\) ) the total number of collisions of molecules with walls per second.

A plasma-screen TV contains thousands of tiny cells filled with a mixture of Xe, Ne, and He gases that emits light of specific wavelengths when a voltage is applied. A particular plasma cell, $0.900 \mathrm{~mm} \times 0.300 \mathrm{~mm} \times 10.0 \mathrm{~mm},\( contains \)4 \%$ Xe in a 1: 1 Ne:He mixture at a total pressure of \(66.66 \mathrm{kPa}\). Calculate the number of Xe, Ne, and He atoms in the cell and state the assumptions you need to make in your calculation.

Suppose you are given two 2 -L flasks and told that one contains a gas of molar mass 28 , the other a gas of molar mass 56 , both at the same temperature and pressure. The mass of gas in the flask \(A\) is $1.0 \mathrm{~g}\( and the mass of gas in the flask \)\mathrm{B}\( is \)2.0 \mathrm{~g}$. Which flask contains the gas of molar mass 28 , and which contains the gas of molar mass 56 ?

The planet Jupiter has a surface temperature of \(140 \mathrm{~K}\) and a mass 318 times that of Earth. Mercury (the planet) has a surface temperature between \(600 \mathrm{~K}\) and \(700 \mathrm{~K}\) and a mass 0.05 times that of Earth. On which planet is the atmosphere more likely to obey the ideal-gas law? Explain.
