The answer is dipole-dipole and dipole-induced dipole forces.

The dipole-induced dipole is a kind of interaction induced by a polar molecule by disturbing the arrangement of electrons.

In methyl cyclohexanone molecules, there is a permanent dipole moment due to dipole moment vectors not canceling.
There is induction of dipole by disturbing the electronic arrangement.
A permanent dipole moment is created in this interaction.
Dipole-dipole interactions are defined as the forces that is formed from the close linkage of permanent or induced dipoles.
These forces are called Van der Waal forces.
Proteins contain a large number of these interactions, which vary considerably in strength.

How many liters of oxygen are required to react completely with 14.8 mol of Al?

Bond [772]

Answer:

296 L

Explanation:

We will need a balanced equation with moles, so let's gather all the information in one place.

4Al + 3O₂ ⟶ 2Al₂O₃

n/mol: 17.4

1. Moles of O₂

$n = \text{17.4 mol Al}\times \dfrac{\text{3 mol O}_{2}}{\text{4 mol Al}}= \text{13.05 mol O}_{2}$

2. Volume of O₂

You haven't given the conditions at which the volume is measured, so I assume it is at STP (0 °C and 1 bar).

At STP the molar volume of a gas is 22.71 L.

$V = \text{13.05 mol}\times \dfrac{\text{22.71 L}}{\text{1 mol }}= \textbf{296 L}$

Define thermal and electrical conductivity, solubility, magnetism, melting and boiling points

Anon25 [30]

Answer:

thermal conductivity: the rate at which heat is transferred by conduction through a unit cross-section area of a material, when a temperature gradient exits perpendicular to the area

electrical conductivity: the measure of the amount of electrical current a material can carry or it's ability to carry a current

solubility: the ability to be dissolved, especially in water

magnetism: a physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects

melting point: the temperature at which a given solid will melt.

boiling point: the temperature at which a liquid boils and turns to vapor

A sample of concrete contains cement, gravel, crushed rocks, sand, and water. Each of these contains different metals and minera

Zepler [3.9K]

As the concrete has cement, gravel, crushed rocks, sand, and water of different physical state and can be separated by physical methods hence it should be called as a mixture.

As the components have significant physical boundaries which clearly identify their presence, the mixture is heterogeneous and not homogeneous.

Thus this is a concrete is a heterogeneous mixture of cement, gravel, crushed rocks, sand, and water

In which case would an electron experience the greatest effective nuclear charge? not all cases describe an atom in the ground s

lisabon 2012 [21]

One electron in an atom experiences the entire positive charge of the nucleus. Coulomb's law can be used in this situation to determine the effective nuclear charge.

In contrast, the outside electrons in an atom with many electrons are drawn to the positive nucleus and repelled by the negatively charged electrons at the same time. The force between two stationary, electrically charged particles can be measured using Coulomb's law inverse-square law, also known as Coulomb's law. Conventionally, the electric force between two charged objects at rest is referred to as the Coulomb force or electrostatic force.

The electron is a subatomic particle with the symbol e or with an electric charge of one elementarily negative charge. The lepton particle family's first generation includes electrons.
