There will be different amounts of HCl consumed in each reaction. As already mentioned, magnesium hydride is a substance that reacts very easily and violently with water, presenting the ability to explode in higher concentrations. This occurs because its exothermic reaction generates enough heat to ignite the hydrogen gas released in the decomposition reaction, leading to a rather dangerous chain reaction. Combination Reaction - Reactions in which two or more reactants combine to form one product are called combination reactions. The presence of silicon also greatly accelerated the reaction rate, producing a far higher peak in the flow rate but cutting short the duration of hydrogen output. Here, the reaction initially produces magnesium oxide (Equation 3), which can continue to produce the hydroxide on reaction with liquid water (Equation 4).
