A 250 mL beaker is submerged in a large container of Liquid X and turned upside down, and another 250 mL beaker is submerged and turned upside down in a large container of Liquid Y. Hydrogen (H2) gas is bubbled into each upside-down beaker until 100 mL of liquid has been displaced. The masses m X and my of hydrogen inside each beaker is then chemically determined.
a. mx will be greater than my
b. m x will be less than my
c. mx will be equal to my
d. It's impossible to predict whether mx or my will be greater without more information.
Answer:
Mx will be less than My.
Explanation:
The correct option is - Mx will be less than My.
Because, liquid X have been higher viscosity and vapor pressure than liquid B.
Vapor pressure of liquid A is greater, so the amount of liquid X will vaporized greater and H2 gas has been displaced greater from the beaker as compared to liquid Y.
The amount of H2 in liquid Y remains greater in beaker as compared to liquid X.
So, Mx will be less than My.

What happens to the conductivity of water when a base is dissolved in it.
Answer:
See Explanation
Explanation:
The conductivity of water refers to how much it conducts electricity. The electrical conductivity of water increases as more ions are dissolved in it.
Hence, increase in concentration of dissolved ions improves the electrical conductivity of water.
Therefore, when a base (which is an ionic substance) is dissolved in water, the concentration of ions present increases and the conductivity of the solution increases accordingly since ions are charge carriers in solution.
The addition of a base to the sample results in an increase in the conductivity of the sample.
Conductivity can be defined as the transfer of charge by the sample. The sample has consisted of the ions that mediate the transfer of charge.
The sample with a high number of ions has consisted of high conductivity and vice versa. The dissolution of acid or base to the solution results in an increase in the number of ions in the solution, and thereby there has been an increase in the charge transfer.
Thus, with the increase in the charge transfer, there has been an increase in the conductivity of the sample.

A gas cylinder initially contains 463 L of gas at a pressure of 159 atm. If the final volume of gas is 817 L, what is the final pressure?
Answer:
The final pressure is 90.1 atm.
Explanation:
Assuming constant temperature, we can solve this problem by using Boyle's Law, which states:
P₁V₁=P₂V₂Where in this case:
P₁ = 159 atmV₁ = 463 LP₂ = ?V₂ = 817 LWe input the given data:
159 atm * 463 L = P₂ * 817 LAnd solve for P₂:
P₂ = 90.1 atmThe final pressure is 90.1 atm.

During the Viking landings on Mars, the atmospheric pressure was determined to be on the average about 6.50 millibars (1 bar = 0.987 atm). What is that pressure in torr and kPa?
Answer:
The pressure is equal to 4.87 torr and 0.649 kPa.
Explanation:
The atmospheric pressure was determined to be on the average about 6.50 millibars.
As 1 bar = 0.987 atm
6.5 mbar = 0.0065 bar
So,
0.0065 bar = (0.0065×0.987 ) atm
= 0.0064155 atm
Since, 1 atm = 760 torr
So, 0.0064155 atm = 4.87 torr
Since, 1 torr = 133.322 Pa
4.87 torr = 649.27 pa
or
4.87 torr = 0.649 kPa
Hence, the required pressure is equal to 4.87 torr and 0.649 kPa.

Which of the following statements are true? Select all answers that are true (this might be more than one answer). Select one or more: a. London dispersion forces are the only type of intermolecular forces that nonpolar molecules exhibit. b. Molecules that have only London dispersion forces will always be gases at room temperature (25 oC). c. None of the listed answers are true. d. The molecules in SO2 (g) exhibit dipole-dipole intermolecular interactions. e. CH3CH2CH3 has stronger London dispersion forces than does CH4.
Answer:
London dispersion forces are the only type of intermolecular forces that nonpolar molecules exhibit.
The molecules in SO2 (g) exhibit dipole-dipole intermolecular interactions.
CH3CH2CH3 has stronger London dispersion forces than does CH4.
Explanation:
London forces result from temporary shifts or distortion in the electron cloud of non-polar molecules. London forces occur in all substances; whether polar or non-polar. However, it is the only kind of intermolecular force in non-polar molecules and noble gases.
Polarity in a molecule stems from difference in electronegativity between the atoms in the molecule. SO2 is a polar molecule due to the magnitude of electronegativity difference between sulphur and oxygen. Hence SO2 exhibit dipole-dipole intermolecular interactions since it is a polar molecule.
The magnitude of London dispersion forces depends on the molar mass and surface area of molecules. CH3CH2CH3 has a higher molar mass and larger surface area than CH4 hence CH3CH2CH3 has stronger London dispersion forces than does CH4.
The following statements which are true include
London dispersion forces are the only type of intermolecular forces that nonpolar molecules exhibit.The molecules in SO2 (g) exhibit dipole-dipole intermolecular interactions.CH3CH2CH3 has stronger London dispersion forces than does CH4.London forces are the only type of intermolecular force found in non polar
compounds and they are responsible for their attractive interactions.
The molecules in SO2 (g) exhibit dipole-dipole intermolecular interactions as
a result of it being polar.
CH3CH2CH3 has stronger London dispersion forces than does CH4
because it is more non-polar and it is the characteristic attraction found in
non-polar compounds.

The value of H° for the reaction below is -72 kJ. ________ kJ of heat are released when 5.5 mol of HBr is formed in this reaction.
Answer:
-198 kJ
Explanation:
Hello there!
In this case, as the reaction is not given but we can see that HBr is formed, we can infer that reaction is:
[tex]H_2+Br_2\rightarrow 2HBr[/tex]
Whereas the -72 kJ per moles of HBr are:
[tex]\frac{-72kJ}{2molHBr}[/tex]
Thus, by multiplying by the formed 5.5 moles of HBr, the total energy release is:
[tex]\frac{-72kJ}{2molHBr} *5.5molHBr\\\\=-198kJ[/tex]

According to the Kinetic Molecular Theory, which container has helium particles with the greatest average kinetic energy?
Answer:
Explanation:
The correct option would be that the average kinetic energy of the gas particles is greater in container B because it has a higher temperature.
According to the kinetic theory of matter, the temperate of a substance is a measure of the average kinetic energy of the molecules of substance. In other words, the higher the temperature of a substance, the higher the average kinetic energy of the molecules of the substance.
In the illustration, the gas in container B showed a higher temperature than that of container A as indicated on the thermometer, it thus means that the average kinetic energy of the molecules of gas B is higher than those of gas A.

When excess magnesium was reacted with dilute sulphuric acid, the reaction was fast at first but
gradually became slower and finally stopped.
Which of the following describe the reaction?
A.
B.
The magnesium was used up.
The sulphuric acid was used up.
The temperature of the mixture decreased.
The magnesium particles became coated with hydrogen gas.
C.
D.
The reactant present in more amounts is called excess reagent. In the reaction between Mg and sulphuric acid, the reaction gradually stopped due to the consumption of the acid. Thus, option B is correct.
What is an excess reagent?An excess reagent is a chemical reactant present in more quantity than the other substance or reactant in the reaction. They are not totally consumed after the reaction ends, unlike the limiting reagent.
In the reaction, magnesium is the excess reagent while dilute sulphuric acid is a limiting reagent that determines the reaction rate and the product formation. At first, the reaction will be fast but gradually will become slow as all dilute sulphuric acid will be consumed slowing downs and stopping the reaction.
Therefore, dilute sulphuric acid will be used up at the end of the reaction.

When two oxygen atoma pair together, they form a double bond to achieve a complete octet which is a stable configuration
When two nitrogen atoms pair together, they form a triple bond to achieve a complete octet which is a stable configuration
Explanation:
The tendency of atoms to achieve a noble gas configuration that is eight valence electrons is said to be octet rule. This is done to attain noble gas configuration and stability.
In order to attain stability the atoms tends to have eight electrons in its valence shell which can be obtained by either by sharing of electrons or complete transfer of electrons.
Hydrogen [tex](H:1s^1)[/tex] has one valence electron each, so sharing of electrons result in formation of single bond and the same electron configuration as the Helium and thus complete its duet.
Halogens [tex](F:1s^22s^22p^5)[/tex] have 7 valence electron each, so sharing of electrons result in formation of single bond. The stable noble gas configuration is attained and thus complete its octet.
Oxygen [tex](O:1s^22s^22p^4)[/tex] has six valence electrons each, so sharing of two electrons result in a double bond. The stable noble gas configuration is attained and thus complete its octet.
Nitrogen [tex](N:1s^22s^22p^3)[/tex] has 5 valence electrons, so sharing of three electrons result in a triple bond. The stable noble gas configuration is attained and thus complete its duet.
