The answer is.............................................. plasma
The Energy of an atom that emits a photon of wavelength 2.21 m is
3.028 × 10⁻¹⁹ J.I attached the working and the answer to the question below. I hope I was able to help.
Please note that C = speed of light, ν = frequency, λ= wavelength, h = Planck's Constant
In conduction, the thermal energy of a particle is transferred to other particles throughout the solid. The particles with more energy are transferred to those with less.
Answer:
D) 7.5 grams
Explanation:
Hello,
In this case, since the percent yield is defined by:

In such a way, since the percent yield is up to 25% and the expected or theoretical amount is 30 g of the product, the actual yield of the reaction is:

Therefore the answer is D) 7.5 grams.
Best regards.
