A student worksheet is available to accompany this demonstration. (Optional) If the flame of a butane fireplace lighter is held above the bursting bubbles, they will produce audible pops as the hydrogen ignites. Pour hydrochloric acid into the Petri dish to a depth of about 5 mm. C) the reaction that corresponds to the Hf for water This, in an experiment to determine the rate of the reaction, measuring the $\ce{H2}$ produced would measure this mechanism, because it is the step in which hydrogen gas is evolved. The net ionic equation for this reaction is: Magnesium reacts with hydrochloric acid according to the equation: Mg(s) + 2 is mixed with solid Magnesium carbonate, it will give carbon dioxide, magnesium chloride and water as results. This demonstration may also be performed using a document projector if a dark background is used. Corks are too porous and will leak. If it really happens concertedly or via an intermediary step ($\ce{H+ + Mg -> Mg+ + H^{. Wear eye protection throughout.
