Usually, the octet is formed when 8 valence electrons are for it to maintain a stable electron configuration. 

Oxygen has 6, so it needs 2 more. 
Hydrogen, however, only needs 2 to form an octet, so it only needs one more electron.

Which equation shows how wavelength is related to velocity and frequency?
Nataly_w [17]

Answer:

The correct option is the option;

\lambda = \dfrac{v}{f}

Explanation:

The wavelength of a wave is the distance between two successive crests of the wave

Therefore, the wavelength, λ, is given by the fraction of the velocity, <em>v</em>, of the wave divided by the frequency, <em>f</em>, (the number of cycles that pass through a point) of the wave

Mathematically, we have;

The \ wavelength, \ \lambda = \dfrac{The \ wave \ velocity, \ v}{The \ wave \ frequency, \ f}

\lambda = \dfrac{v}{f}

2. A chemical analysis of a sample provides the following elemental data:
Vadim26 [7]

Answer:

C3 H6 O2

Explanation:

first divide their mass by their respective molar mass, we get:

30.4 moles of C

61.2 moles of H

20.25 moles of O

now divide everyone by the smallest one of them then we get

C= 1.5

H= 3

O= 1

since our answer of C is not near to any whole number so we will multiply all of them by 2

so,

C3 H6 O2 is our answer
