Find the equilbrium expression (Ka) for the ionization reaction. HCO3-(aq) + H2O(l) ⇆H3O+(aq) + CO32-(aq) Give the expressions for A, B, and C, given the form:

Explanation:

HCO₃⁻(aq) + H₂O(l) ⇆ H₃O⁺(aq) + CO₃⁻²(aq)

if we rewrite using letters

A(aq) + B(l) ⇆ C(aq) + D(aq)

when in aqueous solution, the concentration of the water is not included in the expression of the equilibrium constant because it is assumed constant.

Notice that,  all the stoichiometric coefficients are equal to 1.

pure substance: iron,copper

impure substance: water,charcoal

the answer is the first option

explanation:

just googled it m8. not that hard

lol
