Caption: Magnesium silicide-acid reaction. Demonstrator adding magnesium silicide (Mg2Si) to hydrochloric acid (HCl) to trigger a vigorous reaction. The reaction produces silane gas (SiH4) and magnesium chloride (MgCl2). As it bubbles out of the liquid, the silane gas combusts in oxygen (O2) to produce silicon dioxide (SiO2) and water (H2O). The magnesium silicide was prepared by heating a mixture of magnesium powder and sand (silica, a form of silicon dioxide). Some of the flames and bubbles are also due to unreacted magnesium and magnesium oxide reacting with the acid.
