CaCO3 + HCl = H2O + CO2 balanced

Hey there!

CaCO₃ + HCl → H₂O + CO₂

This equation is impossible to balance.

There must be a mistake in the writing of the equation.

There is Ca in the reactants, but there is no Ca in the products.

The law of conservation of mass states that the products must be equal to the reactants, which means this equation cannot follow the law of conservation of mass.

Therefore, this equation is impossible to balance.

Hope this helps!

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
