The dissociation energy of a molecule is the energy required to break apart the molecule into its separate atoms. The dissociation energy for a particular molecule is 1.12 × 10-18 J. Suppose that this energy is provided by a single photon.

Determine the (a) wavelength and (b) frequency of the photon. (c) In what region of the electromagnetic

(a) 1.78 * 10^(-7) m

(b) 1.69 * 10(15) Hz

(c) Ultraviolet light

Explanation:

(a) To determine the wavelength, we use one of the formulae of energy of a wave:

E = hc/λ

Where h = Planck's constant

c = speed of light

λ = wavelength.

Therefore, wavelength, λ, is:

λ = hc/E

λ = (6.626 * 10^(-34) * 3 * 10^8) / (1.12 * 10^(-18))

λ = 1.775 * 10^(-7) m

This is the wavelength of the photon.

(b) Using formula for speed of a wave, we can find the frequency:

c = λf

Where f = frequency.

f = c/λ

f = (3 * 10^8) / (1.775 * 19^(-7))

f = 1.69 * 10^(15) Hz

This is the frequency of the photon.

(c) By comparing the frequency and wavelength of the photon with the electromagnetic spectrum, the proton is in the region of ultraviolet light.

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
