Determine which molecule in each pair has the stronger intermolecular forces. Explain why. The main reason that NH3 has [ Select ] intermolecular forces than CH4 is that NH3 [ Select ] . The main reason that NO2 has [ Select ] intermolecular forces than CO2 is that NO2 [ Select ] . The main reason that CS2 has [ Select ] intermolecular forces than CO2 is that CS2 [ Select ] .
Answers
Answer:
See explanation
Explanation:
As for NH3 and CH4, the former is a polar molecule and possess a dipole. Hence, in addition to dispersion forces, dipole-dipole interaction as well as hydrogen bonding creates a stronger intermolecular interaction than in nonpolar CH4 where only dispersion forces are in operation.
Between NO2 and CO2, the former possesses a dipole moment while the later does not. As a result of that, dipole interaction are in operation in NO2 while only dispersion forces are n operation in CO2.
Between CO2 and CS2, the both molecules are nonpolar but CS2 has a greater molecular mass than CO2. Recall that the greater the molecular mass of a substance the greater its magnitude of intermolecular forces.
Taking into account the intermolecular forces, you get that:
The main reason that NH₃ has weaker intermolecular forces than CH₄ is that NH₃, being nonpolar, possesses London Dispersion Forces, while CH₄ possesses the Hydrogen Bonding forces.The main reason that NO₂ has the same intermolecular forces than CO₂ is that in NO₂ and CO₂ there are London forces because they are nonpolar molecules. The main reason that CS₂ has the same intermolecular forces than CO₂ is that CS₂ in CS₂ and CO₂ there are London forces because they are nonpolar molecules.Intermolecular forces or bonds are those interactions that hold molecules together. These are electrostatic forces.
Van der Waals forces are weak attractions that hold electrically neutral molecules together. At some point these molecules present an induced dipole, that is, the molecule acquires a partially positive and a partially negative charge momentarily, causing them to attract each other. They are Van de Waals forces: Dipole - Dipole Forces, London Forces, Ion - Dipole Forces.
London Dispersion Forces: occurs between nonpolar molecules due to the movement of electrons. At some point there are more electrons to one side, which, being close to another atom or molecule, the electrons of the second are repelled, originating two instantaneous dipoles, which originate an attractive force. In summary, this type of force occurs because when two molecules approach, a distortion of the electronic clouds of both is originated, generating in them, transient induced dipoles, due to the movement of the electrons, thus allowing them to interact with each other. They are very weak forces.Ion-ion forces: It is the attraction between two ions of different charges: cations (positively charged ion) and anions (negatively charged ion). That is, it occurs between different charged molecules that will tend to form an electrostatic bond between the ends of opposite charges due to the attraction between them.Ion-dipole forces: these are forces of attraction between an ion (an atom that has lost or gained an electron, so it has a charge) and a polar molecule. A molecule is a dipole when there is an asymmetric distribution of electrons because the molecule is made up of atoms of different electronegativity. The ion then binds to the part of the molecule that has its opposite charge: the positive end of the polar molecule is oriented towards the anion (negatively charged ion) and the negative end of the polar molecule is oriented towards the cation ( positively charged ion).Dipole-dipole forces: dipole-dipole forces are forces of attraction between polar molecules. These molecules attract when the positive end of one of them is close to the negative of the other.Hydrogen bonds: they are a type of dipole-dipole force. In this interaction, a molecule that presents hydrogen interacts with another that presents an atom with high electronegativity, such as oxygen, fluorine or nitrogen (O, F, N). In this way, between the hydrogen, which has a low electronegativity and the electronegative atom, an interaction is established, due to their opposite charges.The relative order of magnitude of the intermolecular forces is:
Ion-ion forces> Ion-dipole forces> Hydrogen bonds> Dipole-dipole forces> London Dispersion Forces
Taking into account all the above, it can be said that:
The main reason that NH₃ has weaker intermolecular forces than CH₄ is that NH₃, being nonpolar, possesses London Dispersion Forces, while CH₄ possesses the Hydrogen Bonding forces.The main reason that NO₂ has the same intermolecular forces than CO₂ is that in NO₂ and CO₂ there are London forces because they are nonpolar molecules. The main reason that CS₂ has the same intermolecular forces than CO₂ is that CS₂ in CS₂ and CO₂ there are London forces because they are nonpolar molecules.Learn more:
https://brainly.com/question/17111432?referrer=searchResultshttps://brainly.com/question/14220340?referrer=searchResults350.0 ML of air is at 23.0°C what is the volume at 90.0°C
Answers
Answer:
V=0.430 Liters
Explanation:
First off you need to convert ml to l and celsius to kelvin, in order for them to be in the S.I.
So, 350.0mL is 0.350 L and 23.0 C is (273.15+23=) 296.15 K (you can ignore the 0.15)
From the equation pV=nRT, lets name this equation (1), we can tell that the number of moles, pressure, and R, stay the same. The only thing changing is the volume, and temperature.
With the information given, let's figure out the pressure. From equation (1) if we solve it for the pressure of the gas, p=nRT/V => p=nR*296.15/0.350 => p=846.15 *nR
Now, we have to figure out the volume of the gas at 90.0 C (363.15 K), and solve equation (1) for volume, using the pressure we previously found.
v=nRT/p => v=nR*363.15/846.15*nR => (the nR's from top and bottom go away) v=0.429 L
Since we used 273.15 for the conversion of celsius to Kelvin, we could round up the number to
V=0.430 Liters

Use this image of a greenhouse to help explain how the Earth gets heated through the greenhouse effect.
Answers
Answer/Explanation:
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.
Earth's surface warms up in the sunlight. At night, Earth's surface cools, releasing heat back into the air. But some of the heat is trapped by the greenhouse gases in the atmosphere. That's what keeps our Earth a warm and cozy 58 degrees Fahrenheit (14 degrees Celsius), on average.

Fossil fuels include substances like natural gas, coal, and oil. It is possible for electric cars to run on these fossil fuels. Fossil fuels like coal are burnt up to generate electricity. So when cars run on electricity, they are indirectly tapping into fossil fuels.
As the world continues to seek measures to reduce carbon emissions, electric cars are gradually becoming an option.

Answers
Answer:

Explanation:
Given that,
Initial volume, V₁ = 1.22 L
Initial temperature, T₁ = 286 K
Final volume, V₂ = 2.86 L
We need to find the new temperature of the gas. The relation between the volume and the temperature is given by :
[tex]\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}\\\\T_2=\dfrac{V_2T_1}{V_1}\\\\T_2=\dfrac{2.86\times 286}{1.22}\\\\T_2=670.45\ K[/tex]
So, the new temperature of the gas is equal to 670.45 K.

Answers
When a particle and its antiparticle collide they are converted to energy.
What is collide?A colloid would be a mixture in which a component made up of insoluble particles that are scattered at a microscopic scale is suspended within another component.
What is energy?In order to accomplish work and to produce heat as well as light, energy must be supplied to a body or even to a physical system. Energy would be the quantitative attribute that does this. Energy would be transformed in form but cannot be created and destroyed, according to the rule of conservation of energy.
Annihilation occurs when a particle collides including its anti-particle. The particle and its antiparticle's whole mass are transformed back into energy to produce two gamma-ray photons. You won't find antiparticles in everyday stuff since they typically barely last for a tiny amount of time until annihilation takes place.
Therefore, the correct answer will be option (c).

if the hydrogen ion concentration [H+] in a solution is 1.87 x 10^-11M what is the [OH-]
Answers
By using pH formula, the concentration of hydroxyl ion [OH-] will be 5.3 ×[tex]10^{-4}[/tex] M.
What is pH?
The pH scale is a measurement of hydrogen ion concentration that is used to determine the acidity as well as alkalinity of a solution.
Calculation of [OH-] by using formula of pH.
Given data:
[H+] = 1.87 x [tex]10^{-11} M[/tex]
[OH-] = ?
Calculation of [OH-] is shown below:
It can be calculated by using the formula:
pH = -log [H+]
Put the value of concentration of hydrogen ion [H+] in above formula.
pH = -log (1.87 x [tex]10^{-11} M[/tex])
pH = -log (1.87) -log ( [tex]10^{-11} M[/tex])
pH = -0.27 +11
pH = 10.73
Now, use the formula, pH +pOH = 14
pOH = 14 - pH
pOH = 14 - 10.73
pOH = 3.27
Now, use formula pOH = -log [OH-]
[OH-] = [tex]10^{-pOH}[/tex]
[OH-] = [tex]10^{-3.27}[/tex]
[OH-] = 5.3 ×[tex]10^{-4}[/tex] M
Therefore, the concentration of hydroxyl ion [OH-] will be 5.3 ×[tex]10^{-4}[/tex] M.

Number of moles of SSA = 7/1000 * 0.02 = 1.4 * 10^-4 moles
Total number of moles = 6 * 10^-6 moles + 1.4 * 10^-4 moles
Mole fraction of SSA = number of moles of SSA/ total number of moles.
Mole fraction of SSA = 1.4 * 10^-4 moles/ 6 * 10^-6 moles + 1.4 * 10^-4 moles
Mole fraction of SSA = 0.96
