Here are the answers to question 30: 30. a) The gas being collected in the gas jar is hydrogen gas (H_2). b) The balanced chemical reaction involved in this process is: Zn(s) + 2HCl(aq) ZnCl_2(aq) + H_2(g) c) If concentrated H_2SO_4 is used instead of dilute acid, sulfur dioxide gas (SO_2) will be formed. Concentrated sulfuric acid acts as an oxidizing agent, reacting with zinc to produce sulfur dioxide, zinc sulfate, and water. 3 done, 2 left today. You're making progress.
