Calculate the standard enthalpy of formation of solid Mg(OH)2 given the following data . Become a Patron! For example, the synthesis of magnesium oxide, MgO, is a redox reaction in which oxygen gas oxidizes magnesium metal, while being reduced in the process. Since the oxidation of Mg to form MgO occurs at room temperature, there is no reason to think that there is sufficient energy to break the O2 bond. Determine the limiting reactant, theoretical yield, and precent yield for the reaction. So the products are MgO and Cl2. For the reaction 2 Mg(s) + O2(g) → 2MgO, a reaction mixture contains 33.7 g Mg and 28.0 g O2. What's unusual, however, is that magnesium is reactive enough to be combusted and oxidized in a reaction with carbon dioxide: 2 Mg + CO 2 -> 2 MgO + C. Under normal combustion/oxidation circumstances, oxygen is the reactant. however, he was also adamant that this was not a combustion reaction, when it our text book it specifically gave us this very same example as a type of combustion reaction. a) Determine the limiting reactant for the reaction. 2Mg (s) + O2 (g) ---> 2MgO (s) delta H = -1203.6 KJ. How many grams of MgO are produced from the complete reaction of 94.2 g Mg? Which reactant is left in excess and how much ? Today in class my chem teacher was insistent that 2Mg + O2 = 2MgO was a synthesis reaction. Reaction Type. Each magnesium atom loses two electrons, so two magnesium atoms will lose a total of four electrons. c) Determine the percent yield for the reaction.
