Urgent! consider the following decomposition reaction of ammonium carbonate ((nh4)2co3):
(nh4)2co3 (s) _ 2 nh3 (g) + co2 (g) + h2o (g)
in one experiment at 25.0ác, a sample of pure (nh4)2co3 is placed in an evacuated 2.00 l vessel. at equilibrium, the total pressure is found to be 0.8944 atm.
(a) determine the equilibrium partial pressure of each gaseous species.
(b) determine the mass of ammonium carbonate ((nh4)2co3) that must have reacted in order to achieve equilibrium.
(c) determine the value of kp assuming that the reaction temperature is 25.0ác.

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant
