One liter of argon gas at 300 k is expanded against constant external pressure from 10 to 100, at which point mechanical equilibrium is achieved. after the expansion, the temperature of the gas has fallen to 270 k. detemine q, w, ae and ah for this process. then do the same calculation, assuming molecular hydrogen vapor. treat both ar and h2 as ideal gases.

answer: h+ its less than oh

explanation:

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
