What is the balanced form of the chemical equation shown below? C12H22011() + O2(g) → H20() + CO2(9)
A. C12H220110) + O2(g) → H20(1) + CO2(g)
B. C12H22011() + O2(g) → 11H20() + CO2(g)
C. C12H22011() + 1202(9) ► 11H20() + 12C02(9)
D. C12H220110) + O2(g) → 11H20(1) + CO2(9)

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
