Determine the limiting reactant, theoretical yield, and precent yield for the reaction. 2018,,, 293-329. to form magnesium oxide. Start by assigning oxidation numbers to all the atoms that take part in the reaction--it's actually a good idea to start with the unbalanced chemical equation. Magnesium oxide (Mg O), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide).It has an empirical formula of Mg O and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding. Solved: Predict the product of the following reaction: Mg(s) + O2(g) arrow (blank). 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.
