When 2.500 g of sulfur was burned completely in oxygen to form SO2(g), the temperature of a bomb calorimeter with the heat capacity 3.559kJ/oC/was raised from 22.00oC to 28.55oC. Calculate ΔHo (kJ) for the reaction per mole of SO2 formed.

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
