(a)[1]
Heat a small sample of ammonium carbonate in a test-tube. Describe how you can tell that all of the ammonium carbonate has decomposed.
(b)[3]
Calculate the combined volume of ammonia and carbon dioxide, measured at room temperature and pressure, produced when 4.80 g of ammonium carbonate is fully decomposed.
(c)[2]
Describe a chemical test for the ammonium ion, giving both the test used and the observation made.
(d)[2]
Write the ionic equation, with state symbols, for the reaction of aqueous ammonium carbonate with dilute hydrochloric acid.
(e)[2]
Solid ammonium carbonate does not conduct electricity, whereas aqueous ammonium carbonate does conduct electricity. Explain these two observations.
