The strongest intermolecular force is the hydrogen bond in water (H2O).

What is intermolecular force?
Intermolecular forces
are those that develop between the molecules of a substance and can cause them to attract or repel one another. The type of intermolecular force that is present in the matter determines all of the material's physical and chemical properties.

Interactions between dipoles
Involvements of Ion-Dipoles
Dipole Interactions Induced by Ions
DID Interaction: Dipole Induced DID
London Forces or Dispersion Forces
These five intermolecular force types are listed above.


The intermolecular forces were in this order:
The strongest force is ion-dipole force.
the hydrogen bond
Force between dipoles
the least powerful is the dispersion force.
The strongest intermolecular force is therefore the hydrogen bond in H2O.

Hydrogen bond in H2O is the strongest intermolecular force.

What is intermolecular force?

Intermolecular forces are those that form between a substance's molecules and have the ability to attract and repel one another. All the physical and chemical properties depend on the type of intermolecular force present in the matter.

Dipole-Dipole Interactions

Ion-Dipole Interactions

Ion Induced Dipole Interactions

Dipole Induced Dipole Interaction

Dispersion Forces or London Forces.

These above are the five types of Intermolecular forces-

The order of the Intermolecular forces where

Ion-dipole force is the strongest

Hydrogen bond

Dipole-dipole force

and dispersion force is the weakest.

Hence, the Hydrogen bond present in <u>H2O is the strongest</u> intermolecular force.

The [H+] of a solution can be determined from the pH using the equation: [H+] = 10 - pH ... Where: [H+] = hydrogen ion concentra
padilas [110]

Answer:

pH = -log₁₀ [H⁺]

Explanation:

pH is a value in chemistry used in to measure solution trying to determine each quality, purity, risks for health of some products, etc.

As you write in the question, [H⁺] = 10^(-pH)

Using logarithm law (log (m^(p) = p log(m):

log₁₀ [H⁺] = -pH

And

<h3>pH = -log₁₀ [H⁺]</h3>

Trava [24]

Answer:

It takes 1.32x10⁻⁷s for the concentration of A to fall by a factor of 8

Explanation:

The equation that represents a first-order kinetics is:

Ln ([A] / [A]₀] = -kt

<em>Where [A] is actual concentration, [A]₀ is initial concentration, K is rate constant (For the given problem, 1.57x10⁷s⁻¹ and t is time.</em>

<em />

As you want the time when you have [A] in a factor of 8 = [A] / [A]₀ = 1/8

Replacing:

Ln ([A] / [A]₀] = -kt

Ln (1/8) = -1.57x10⁷s⁻¹*t

t = 1.32x10⁻⁷s

<h3>It takes 1.32x10⁻⁷s for the concentration of A to fall by a factor of 8</h3>
