what type of intermolecular force is found between a) f2 and cl2 ? London dispersion force b) water molecules ? hydrogen bonds ?

Answers

Answer 1

London dispersion forces are the only intermolecular forces that exist between fluorine and chlorine because they are both non-polar covalent compounds.

What produces the dispersion forces in London?

The coulombic interaction between instantaneous dipoles lead to London dispersion forces.All molecules (and atoms) exhibit dispersion forces, which are typically higher for heavier, more polarizable, and molecules with wider area areas.

By London forces, what do you mean?

The intermolecular forces or attraction that hold molecules together are known as London forces.Although they are a vander waal's force, they are the only one found in substances without polar dipole molecules.

What is nuclear reaction?

There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.

In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.

The group 17 of the periodic table contains bromine(Br), iodine(I), Chlorine(Cl) and fluorine(F).

Among all the elements of the group 17. Fluorine is the smallest in size.

Because of the small size of fluorine it has the highest electronegativity in group 17.

This high electronegativity makes it a very active non metal. It provides a very high oxidizing power and low dissociation energy to the fluorine atom.

A) It is tetrahedral because there are four bonded pairs around oxygen.



B) It is bent because there are four bonded pairs around oxygen.



C) It is tetrahedral because there are two bonded pairs and two lone pairs around oxygen.



D) It is bent because there are two bonded pairs and two lone pairs around oxygen.

Answers

Answer: D

Explanation:

Water is comprised of 2 Hydrogen atoms and 1 Oxygen atom. This gives us a total of 8 valence electrons to form bonds with.

Because Hydrogen is in first row of elements it can only hold a total of two electrons. This means each Hydrogen holds 2 electrons.

But that means there are four more electrons. VSEPR theory is basically how electron repulsion causes atoms to arrange in different ways.

There will be four electrons left on the oxygen because they can not go anywhere else. This will cause the hydrogen molecules to move away from the lone electrons and cause a bent geometry rather than a straight-line geometry.

O C. The absorption of a free-moving neutron by the atom's nucleus
OD. The nucleus absorbing freely moving protons

Answers

C. The absorption of a free-moving neutron by the atom's nucleus

In a nuclear fission reaction, the nucleus of an atom becomes unstable when it absorbs a free-moving neutron. This can cause the nucleus to break apart into two or smaller fragments, releasing a large amount of energy in the process. Other factors, such as the temperature and pressure of the surrounding environment, can also affect the stability of the nucleus, but the absorption of a neutron is typically the primary cause of instability in a nuclear fission reaction. Control rods, which are used to regulate the rate of the reaction, do not directly cause the nucleus to become unstable, and the absorption of protons by the nucleus is not typically a factor in nuclear fission reactions.

Why is dimethylformamide a polar aprotic solvent?

Answers

Due to its polar nature and lack of OH or NH groups, dimethylformamide is a polar aprotic solvent. The molecule is made polar by its polar C=O and C-N links. The molecule is aprotic because neither O-H nor N-H bonds exist.

The inability of polar aprotic solvents to form hydrogen bonds with the substrate is referred to as eroticism. They lack hydrogen atoms that can form hydrogen bonds and do not contain any hydrogen atoms that are directly coupled to an electronegative atom.

As illustrations, consider acetone, chloroform, dichloromethane, and other aprotic solvents.

"Borderline" Polar Aprotic Solvents Have Low (10) Dielectric Constants And Small Dipole Moments :

Compared to nonpolar solvents, these solvents have slightly higher dielectric constants (between 5 and 20). They are suitable "general purpose" solvents for a variety of processes due to their moderate polarity. Because they lack O-H or N-H bonds, they are "aprotic." They just operate as the conduit for our aims; they don't take part in the reactions.

With High (>10) Dielectric Constants, Four Key Polar Aprotic Solvents

These solvents all have high dielectric constants (>20), but they don't engage in hydrogen bonding (no O-H or N-H bonds). They can dissolve charged species like different anions utilized as nucleophiles due to their high polarity. These nucleophiles are more reactive because they are comparatively "free" in solution due to the absence of hydrogen bonding in the solvent. These solvents do not engage in reactions in the way that we need them to.

at what point in the titration does the concentration of acetic acid equal the concentration of the acetate ion

Answers

If you were titrating acetic acid with a base, the equivalence point would be where you had added as much base to the solution as acetic acid (i.e. moles of base vs moles acid). This is the point at which all of the acetic acid has been neutralised.

solution's concentration is described as the quantity of solute in a given size of the solution. It can be explained as follows: Mass divided by the mass percentage of a remedy corresponds mass of solute/mass of solution 100. Subtract the solute's mass from of the overall volume of the solution. Calculate C = m/V, where m seems to be the solute's mass and V is indeed the volume of the solution. Divide this same values you discovered for mass and volume to discover the concentration of your solution.
