Answer to Question #300379 in Math for dylan

Question

Square brackets, [], indicate the concentration of a particular chemical and each bracketed term can be considered as a term like x in more familiar equations.

This concentration will increase as CO₂ builds up in the atmosphere.  The carbonic acid dissociates (comes apart) in water over two stages.  The first stage reaction is,

H₂CO₃ Û HCO₃^- + H⁺                                                                                                    (3)

and we can express the equilibrium concentrations of these chemicals as,
