Problem
During a gas-generation demonstration, a teacher places 0.500g of solid ammonium carbonate into a test tube and quickly adds excess 6.0M hydrochloric acid. Vigorous bubbling begins immediately, and a colorless gas is released. After the reaction subsides, only a clear liquid remains in the tube.
(a) Write the balanced molecular equation (including physical states) for the reaction between solid ammonium carbonate and aqueous hydrochloric acid.
(b) Rewrite the reaction from part (a) as a complete ionic equation. Represent all species that exist in aqueous solution as dissociated ions.
(c) Write the net ionic equation for the reaction.
(d) Calculate the theoretical volume, in liters at 25∘C and 1.00atm, of carbon dioxide gas produced. Assume ideal-gas behavior.
(e) Explain why chloride ion is a spectator in this reaction, referencing both the chemical equations and the observable macroscopic evidence provided in the scenario.
