Carbon monoxide and water vapor, each at 200. Torr, were introduced into a 250. mL container. When the mixture reached equilibrium at 700.°C, the partial pressure of CO2(g) was 88 Torr. Calculate the value of K for the following equilibrium.
The filtrate after the removal of the black precipitate was basified with 6M ammonia. This when treated with 3M ammonium carbonate, it gave a white precipitate. This white precipitate was dissolved in 6M acetic acid and basified with ammonia(6M).
