Given the speed of light (3.00 × 108 m/s) and a wavelength 5.9 × 10-7 m, what is the frequency?
Cerrena [4.2K]
Wavelength x Frequency = Speed

So, 5.9 x 10^-7 x F = 3 x 10^8

Rearranging the equation, we get:
F = (3 x 10^8)/(5.9 x 10^-7) = 5.08 x 10^14 Hz

Hope I helped!! xx

How does percent composition by mass contribute to writing a balanced equation?
Mariulka [41]

Answer:

mass composition is very essential in obtaining a balanced equation

Explanation:

to have a completely balanced equation that means the right hand side being your reactants must be equal to the right hand side being your product. both sides need to have equal mass composition, when calculating the mass composition make sure both sides are equal if not consider revisiting the number of moles on both sides to ensure they all balance

I have a sample of galena. It appears there may be some gold in it. It is a piece of raw ore so I took it to a metallurgist and
Lubov Fominskaja [6]

Yes it is possible

Explanation:

Galena and gold can become encrusted together. They can form together in the same geologic setting.

  • Gold usually occurs freely in nature uncombined with other atoms.
  • Galena is the largest ore of lead.
  • Both minerals can become twinned under appropriate geologic conditions.
  • They are usually seen in pegmatitic intrusions in a rock body as product of late stage melt crystallization.
