Answer:

is a well-sustantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.such fact- supported theories are not "guesses" but reliable accounts of the real worlds.

What is the frequency of a 6.14 x 10^4 m wave

andrew11 [14]

From the information give, I'm going to assume the wave is in a vacuum...

You use the equation: f= $\frac{C}{Wavelength}$ where c is the constant for speed of light ( $3.00 x 10^{8}$

so f= $\frac{3.00x10^{8}}{6.14x10^{4}}$

f= 4.89 x $10^{3}$ Hz (approximately)

The N H 2 group makes the molecule an amine. Like alcohols, amines can participate in hydrogen bonding. If the drawn molecule en

lesantik [10]

Answer:

a hydrogen bond between the hydrogen of water and the nitrogen of the amine

a hydrogen bond between the oxygen of water and a hydrogen from the -NH2 group

Explanation:

A hydrogen bond is formed between molecules in which hydrogen is bonded to a highly electronegative element.

In amines, hydrogen is bonded to nitrogen while in water, hydrogen is bonded to oxygen. Both are highly electronegative elements hence hydrogen bonding is possible between amines and water.

This hydrogen bond may involve;

The hydrogen of water and the nitrogen of the amine

The oxygen of water and a hydrogen from the -NH2 group

Within a single molecule of water, two hydrogen bonds are bonded to a single oxygen atom by_______.However when there are multip

Gnesinka [82]

Answer:

covalent bonding, hydrogen bonding

Explanation:

<u>The molecular formula of water is $H_2O$ in which the two hydrogen atoms are connected to the oxygen atom via covalent bonds which means that the electrons are shared in the bond.</u>

Hydrogen bonding is a special type of the dipole-dipole interaction and it occurs between hydrogen atom that is bonded to highly electronegative atom which is either fluorine, oxygen or nitrogen atom.

Partially positive end of the hydrogen atom is attracted to partially negative end of these atoms which is present in another molecule. It is strong force of attraction between the molecules.

<u>Thus, when multiple water molecules are there, there are connected by hydrogen bonding.</u>
