PLS HELP I will giveist I am doing a science lab report on edge.
Also it is on comparing different material on earths surface absorb heat and to understand how to angle of insolation affects the heating of earths surface.
I have two questions.
1. what is your hypothesis for this experiment?
2. what methods are you using to test this hypothesis?
BTW THIS IS SCIENCE, sorry if the subject confuses you but there was not science subject so yea. PLS HELP

personal, she chose to do it.

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
