Magnesium react with oxygen to produce magnesium oxide. This is an exothermic reaction. Thus, to balance the O2 we put a 2 in front of the MgO. >> I'd probably hide from them a lot...I get nervous easily. What is the reaction #2Mg(s) + O_2(g) -> 2MgO(s)# is an example of what type of reaction? Determine the limiting reactant, theoretical yield, and precent yield for the reaction. (0.41555 mol Mg) x (2/2) x (40.30449 g MgO/mol) = 16.7 g MgO in theory, (11.9 g) / (16.7 g) = 0.713 = 71.3% yield, you need to give the amount of Magnesium, because you can only find the limiting reactant when one of the reactants is in excess. , 1 a bright, hot flame how many grams of glucose would be Hiroki ( < 3 but!
