What does an emission spectrum look like? A. It is a set of lines corresponding to photon emission wavelengths.
B. It is a white light source separated into a band of colors.
C. It is a graph showing the temperature dependence of emissions.
D. It is a band of colors with dark lines at absorption wavelengths.
SUERIT

It should be B

The answer is It is a set of lines corresponding to photon emission wavelengths.

Explanation:

I just did it on A pex and this is correct. Maybe there is a question with similar wording that is making other people get the answer wrong so make sure that your question says "What does an emission spectrum look like" and then your answer will be A.

i look it up online and i'll tell you

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
