Carbon dioxide dissolves in water to form carbonic acid, which
is primarily dissolved CO2. Dissolved CO2 satisfies the equilibrium
equation.The acid dissociation constants listed in most standard
reference texts for carbonic acid actually apply to dissolved CO2.
For a CO2 partial pressure of 3.2×10–4 bar in the atmosphere, what
is the pH of water in equilibrium with the atmosphere? (For
carbonic acid Ka1 = 4.46× 10–7 and Ka2 = 4.69× 10–11).

A. The formation of organic compounds by the reaction (II)
sulfide and carbonic acid is described by the following equaition:
2 FeS + H_2CO_3 ---> 2 FeO + 1/m (CHOH)_n + 2 S. How much FeO is
produced starting with 1.50 g FeS and 0.515 moles of H_2CO_3 if the
reaction results in a 75.50% yield?
