What is gibbs free energy? a) the result of the product of the temperature and entropy of a change, subtracted from the enthalpy of the change. b) the result of the product of the temperature and enthalpy of a change, subtracted from the entropy of the change. c) the result of the product of the temperature and entropy of a change, added to the enthalpy of the change. d) the result of the product of the temperature and enthalpy of a change, added to the entropy of the change.

you gotta add the following molecules so we can give u an answer

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
