The distance from the trough of one wave to the trough of another wave is wave amplitude

Chemistry

Alexxandr [17]3 years ago

This is actually incorrect, the distance as stated above either from trough to trough or from crest to crest within a corresponding wave, would be referred or called as the wavelength of the given wave.

No, that would be the wavelength. It would also be equal to the distance from peak to peak. The amplitude is the distance from the midpoint to the peak or from the midpoint to the trough

List the numbers of protons, neutrons, and electrons in Chlorine-18. (3 points)
Mama L [17]

The electronic configuration of Chlorine is 1s2 2s2 2p6 3s2 3p5.


There are three energy levels in chlorine


First energy level is n=1 has 1s2 so total 2 electrons


Second energy level is n=2, 2s2 2p6 so total 2+6= 8 electrons


Third has 3s2 3p5 electrons just 7 total... p can contain 6 electrons but only 5 are present. So the third level has lesser number of electrons than that can be filled

What is the mass prevent of manganese (mn) in potassium permanganate (KMnO4)​
oksian1 [2.3K]

Answer:

               Mass percent of Mn is 34.76 %

Explanation:

                    <em>Mass percent</em> of an element is the mass of that element divided by the total mass of the elements forming that compound (or molecular mass.

So,

Mass percent of Mn will be given as,

          %Mn  =  Atomic Mass of Mn / Molecular Mass of KMnO₄ × 100

So,

Atomic Mass of Mn  =  54.94 g/mol

Molecular Mass of KMnO4  =  158.034 g/mol

Putting values in above formula,

          %Mn  =  54.94 g/mol ÷ 158.034 g/mol × 100

          %Mn  = 34.76 %

The substance whose lewis structure shows three covalent bonds is
Gnoma [55]

The substance whose Lewis structure shows three covalent bonds is Nitrogen gas molecule.

<h3>What is Lewis structure?</h3>

Lewis structure is a dot structure which gives idea about the number of valence electrons that are involved in the bonding within the molecule.

Lewis dot structure of nitrogen gas will be expressed as in the attached image, where between two nitrogen atoms triple bond is present. That triple bond is formed by the sharing of electrons and known as covalent bonds.

Hence in nitrogen gas molecule three covalent bonds is present.
