Draw the Lewis structure of carbonic acid, H2CO3. Use formal charge to prove you have a favorable structure. Use resonance to show how the carbonate ion is stabilized. How many resonance structures are required to describe the carbonate ion (count all the main contributors)?

answer carbon and three oxygen atoms;

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
