Intermolecular forces are all some kind of: lecture 9

Answers

Answer 1

All intermolecular forces include electrostatic attraction in some way.

Electrostatic interactions are the source of intermolecular forces; this means that they are created when positively and negatively charged species come into contact with one another. Intermolecular interactions, much like covalent and ionic bonds, are the result of the addition of components that are both attractive and repulsive. The electromagnetic forces of attraction or repulsion that act between atoms and other types of neighboring particles, such as atoms or ions, are examples of intermolecular forces, also known as secondary forces. An intermolecular force, also known as an IMF (or secondary force), is the force that mediates the interaction between molecules.

Indicate whether each statement is true or false. Drag the appropriate statements to their respective bins. the octet rule is based on the fact that filling in all s and p valence electrons in a shell gives eight electrons. compounds in which nitrogen is the central atom are frequent exceptions to the octet rule because they have too many electrons surrounding the nitrogen. boron compounds are frequent exceptions to the octet rule because they have too few electrons surrounding the boron. the si in sih4 does not follow the octet rule because hydrogen is in an unusual oxidation state.

Answers

Answer:

the octet rule is based on the fact that filling in all s and p valence electrons in a shell gives eight electrons--- True

boron compounds are frequent exceptions to the octet rule because they have too few electrons surrounding the boron......True

compounds in which nitrogen is the central atom are frequent exceptions to the octet rule because they have too many electrons surrounding the nitrogen...... false

the si in sih4 does not follow the octet rule because hydrogen is in an unusual oxidation state......false

Explanation:

The octet rule simply means that atoms tend to be stable when they have eight electrons in their outermost shell. This rule mostly applies to the s and p orbitals and not to the d and f orbitals. The sum of the total electrons in the outermost s and p orbitals is often equal to eight for an atom to be considered stable, for example, the noble gases.

Boron often forms compounds which has less than eight electrons around the boron central atom because the compounds of boron often have a sextet of electrons owing to the fact that boron is trivalent and forms mostly covalent compounds.

Nitrogen compounds mostly obey the octet rule and do not have excess electrons. The oxidation state of hydrogen in SiH4 is not unusual.

Describe what happens to the molecules in the ice as temperature of the ice increases

Answers

Answer:

When you heat ice, the individual molecules gain kinetic energy, but until the temperature reaches the melting point, they don't have energy to break the bonds that hold them in a crystal structure. They vibrate more quickly within their confines as you add heat, and the temperature of the ice goes up.

Answer:

As energy is transferred to the water molecules in the ice, the motion of the molecules increases. The motion of the molecules increases enough that it overcomes the attractions the water molecules have for each other causing the ice to melt.

A bottle contains 2.5 moles of KOH dissolved in water, and the molarity of the solution is 0.16 M.

What volume of solution is in this bottle?

Answers

Answer:

V = 15.6 L

Explanation:

Hello there!

In this case, according to the definition of molarity in terms of the moles of solute divided by the volume of the solution, it is possible for us to write:

[tex]M=n/V[/tex]

Thus, given the moles and concentration of the solution, we can find the volume as shown below:

V=n/M

Therefore, we plug in the given data to obtain:

V = 2.5mol /(0.16mol/L)

V = 15.6 L

Answers

Answer:

See explanation

Explanation:

We know that 1 mole of a gas occupies 22.4 L

Hence, 1.65 moles of nitrogen gas occupies 1.65 moles * 22.4 L/1 mole = 36.96 L or 3.696 * 10^1 L = 3.70 * 10^1 L

The exponent of the scientific notation answer = 1

The temperature of 200 mL of gas originally at STP is changed to –25o C at constant volume. Calculate the final pressure of the gas in mmHg.

Answers

Answer:

691.6 mmHg

Explanation:

At standard temperature and pressure, temperature of a system = 273K, and pressure= 1atm

T1= 273.15K

P1= 1atm

T2= (–25°C +273.15 )= 248.15K

From Gay-Lussac's law which expressed that at constant volume, pressure of a particular mass of gas is directly proportional to temperature . It can be expressed as

P1 / T1 = P2 / T2

Where P1= initial pressure

T2= final temperature

T1= initial temperature

P2= final pressure

Making P2 subject of the formula

P2= (P1 × T2)/ P1

Substitute the values we have

P2= (1 atm × 248.15K)/273.15

P2= 0.91 atm

But

1atm= 760 mmHg

0.91 atm= X mmHg

If we cross multiply we have

X mmHg= (760× 0.91)/1

= 691.6 mmHg

Hence, the final pressure of the gas in mmHg is 691.6 mmHg

Gibbs free energy is a quantity that is used to measure the maximum amount of work done in a thermodynamic system when the temperature and pressure are kept constant.

Gibbs free energy is denoted by the symbol ‘G’. Its value is usually expressed in Joules or Kilojoules.

Gibbs free energy can be defined as the maximum amount of work that can be extracted from a closed system.

Gibbs free energy to determine the spontaneity of a process.

A sample of gas is kept at a temperature of 300 k, a volume of 1.45L, and a pressure of 3.00 kPa. How many moles of has are in the sample

Answers

Answer:

the number of moles of the gas is 0.00174 mol.

Explanation:

Given;

temperature of the, T = 300 K

volume of the gas, V = 1.45 L

Pressure of the gas, P = 3.0 kPa

The number of moles of the gas is calculated using Ideal gas equation, as follows;

PV = nRT

Where;

n is number of moles of the gas

R is the ideal gas constant, = 8.315 L.kPa/mol.K

n = PV / RT

n = (3 x 1.45) / (8.315 x 300)

n = 0.00174 mol.

Therefore, the number of moles of the gas is 0.00174 mol.
