Chelsea fills four bottles with water. She then places the four bottles of water in the sun. Each bottle contains one-half liter of water. After a few hours, Chelsea measures the water temperature in each bottle. Based on what Chelsea learned from measuring the temperature in each water bottle, why do you think most solar panels are dark in color?

the right answer is c i just did the question.

idk what is it? is this a question that you know the answer or u dont

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
