Answer:

HYDROGEN BONDING

Explanation:HYDROGEN BONDING is the major intermolecular force and interaction taking place when water and ethanol are mixed.

Hydrogen bond is a weak inter-molecular force of attraction which occurs when the partially charged Negative end of an oxygen atom from one oxygen molecule attracts and interacts with the partially charged Positive end of the Hydrogen atom in another Molecule, Hydrogen bonds are also known as dipole-dipole bonds.

Answer:

Hydrogen bond.

Explanation:

Ethanol which has general formula of CnH2n+1OH; a polar –OH group, which hydrogen bonds to water hence, makes ethanol soluble. This -OH group undergoes an intermolecular attraction with water molecules forming Hydrogen bond with the Oxygen as well as the hydrogen.

Alkanols have a trend in which solubility decreases as the CnH2n+1-alkyl group increases. This is because the alkyl group is not water-soluble (hydrophobic) hence its inability to form hydrogen bond with individual water molecules.

What mass of mgf2 is contained in 80.85 g of a 22.4% by mass solution of mgf2 in water?

Aleks [24]

Formula: % by mass = (mass of solute / mass of solution] *100

Data:

mass of solution = 80.85 g

% by mass = 22.4%

Unknown = mass of solute

Solution

% by mass = (mass of solute / mass of solution] *100 = >

mass of solute = % by mass * mass of solution / 100

mass of solute = 22.4 * 80.85 / 100 = 18.11 g

Answer: 18.11 g

A. Match the term with its definition. (1 point)

Assoli18 [71]

Taking into account the definition of wavelength, frecuency and propagation speed:

Frequency: The number of waves passing a point in 1 second.
Wavelength: The distance between two adjacent wave peaks.
Velocity: The direction and speed at which a wave is traveling.

The equation that illustrates the relationship between wave velocity, frequency, and wavelength is v = f×λ.

<h3>Wavelength</h3>

Wavelength is the minimum distance between two successive points on the wave that are in the same state of vibration. It is expressed in units of length (m).

<h3>Frequency</h3>

On the other side, frequency is the number of vibrations that occur in a unit of time. Its unit is s⁻¹ or hertz (Hz).

<h3>Propagation speed or velocity</h3>

Finally, the propagation speed is the speed with which the wave propagates in the medium, that is, it is the magnitude that measures the speed at which the wave disturbance propagates along its displacement.

The propagation speed relate the wavelength (λ) and the frequency (f) inversely proportional using the following equation:

v = f×λ

All electromagnetic waves propagate in a vacuum at a constant speed of 2,998 x 10⁸ m / s, the speed of light.

Therefore, the previous expression establishes an inversely proportional relationship between the frequency and the wavelength: The higher the frequency, the lower the wavelength and when the frequency is lower, the greater the wavelength.

<h3>Summary</h3>

In summary, the definition of frequency, wavelength and velocity are:

Frequency: The number of waves passing a point in 1 second.
Wavelength: The distance between two adjacent wave peaks.
Velocity: The direction and speed at which a wave is traveling.

Finally, the equation that illustrates the relationship between wave velocity, frequency, and wavelength is v = f×λ.

Why can’t an atom lose or gain a proton

Veronika [31]

Explanation:

Atoms never gain protons; they become positively charge only by losing electrons. A positive ion is called a cation (pronounced: CAT-eye-on). You may have notice that the number of neutrons in each of these ions was not specified.
