Sci-fi episode where children were actually adults. Illustration of an oxidation-reduction reaction. What is the word equation for hydrochloric acid and magnesium? In the first flask there is four times the stoichiometric quantity of Mg present, so the balloon inflates to a certain extent as all of the HCl reacts to form hydrogen gas; the indicator changes from red to blue, indicating that the acid was used up; and excess Mg is visible in the bottom of the flask when the reaction is finished. In the third flask there is one quarter of the stoichiometric quantity of Mg so the balloon is noticeably smaller than the other two since the Mg is used up before all of the HCl is converted to hydrogen gas and the indicator stays red, showing that there is still acid present. Discussion. I would therefore deduce that the step: 4. Why don't objects get brighter when I reflect their light back at them?
