Unformatted text preview: Mg (s) + 2HCl (aq) ------ MgCl2 (s) + H2 (g) 2H2O ------ 2H2 + O2 2Mg + O2 ------ 2MgO If you were to measure the mass of magnesium and hydrochloric acid before combining them in the test tube, how would that mass compare to the mass of reactants left in the test tube after the reaction? Explain your answer and how it corresponds to the law of conservation of mass. The mass would have to stay the same due to the law of conservation of mass. One of the reactions you conducted can actually be categorized as TWO different types of reactions. Which reaction is this, and what are the two types of reactions? Burning Magnesium can be categorized as both a synthesis and combustion reaction ....
