What products and reactants are in carbonic acid

Reactant = carbonic acid. Products = carbon dioxide and water.

Explanation:

Carbonic acid decomposes into carbon dioxide and water.

The substance to the left of the reaction arrow (carbonic acid) is the reactant.

The substances to the right of the reaction arrow (carbon dioxide and water) are the products.

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
