Magnesium is the limiting reactant in this experiment: Calculate the theoretical yield of MgO for each trial. Determine the percent yield of MgO for each trial. Determine the average percent yield of MgO for both trials.

Inside a flashbulb, oxygen surrounds a thin coil of magnesium. when the flashbulb is set off, a chemical reaction takes place in which magnesium combines with oxygen to form magnesium oxide. which of the chemical equations matches the reaction above? a. mg + o2 mgo2 + energy b. 2mg + o mg2o + energy c. 2mg + o2 2mgo + energy d. mg + o mgo + energy
