A student has two separate test tubes containing hydrochloric acid.
The student adds a spatula measure of zinc carbonate, ZnCO3\text{ZnCO}_3ZnCO3, to the first test tube and a piece of zinc metal, Zn\text{Zn}Zn, to the second test tube.
Explain what the student would see in each test tube and the tests that they should carry out to identify the gases produced.
Your answer should include word equations for the reactions that would take place.
