Please read the example before answering thank you.

I need the mass balance not a balanced equation I am aware that the equation is balanced. But I need the Mass balance.

To demonstrate what I am talking about I have provided the following as a go by.

Reaction

Lime dissolution by carbon dioxide (1)

Ca(OH)₂ + 2 CO₂ -> Ca²⁺ + 2HCO ₃^-

Mass Balance for (1)

Mass Ca(OH)_{2 in} = Mass of Ca(OH)_{2 out} + Mass of Ca²⁺ _out

Mass of CO_{2 in} = Mass of of CO_{2 out} + Mass of HCO ₃^- _out

Need the Mass balance for Limestone dissolution by carbon dioxide I need this for the second eqaution.

Limestone by carbon dioxide

CaCO₃ + CO₂ + H₂O ----> Ca²⁺ + 2 HCO3 ^-

And an explanation if possible Thank you.
