A substance is found to consist of 1.900g of silver, 0.250g of nitrogen, and 0.850g of oxygen. what is the percent by mass of ox
Galina-37 [17]
The  percentage  by mass  of  oxygen  in  the  compound

find  the total  mass=(  1.900+  0250 +0.850) =  3
the  percentage  mass  mass of  oxgyen/total  mass  x100

that  is  (0.850/3)  x100=28.33%

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.
