Which of the following shows the event in the order that they occur? W = ear drum vibrates X = air around cymbals vibrates Y = cymbals vibrate Z = cymbals are hit. A. W - X - Y - Z
B. Z - Y - X - W
C. Z - X - Y - W
D. Y - Z - X - W

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
