How did this gas behave in the presence of flame? B) Write a balanced chemical equation describing the reaction of Zn and hydrochloric acid C) What gas was produced by the decomposition of hydrogen peroxide? What happened when the smoldering toothpick came in contact with the gas? D) Write a chemical equation describing the reaction of Mn and hydrogen peroxide. E) Compare the behavior of the mixture of cases in the presence of flame. How would you test whether an unknown gas sample contains hydrogen or oxygen?
