Many watches are powered by small, flat batteries called button cells. One common type of button cell contains the metal zinc. When zinc in the battery
combines with oxygen in the air, zinc oxide forms. This process generates the
electricity that powers the watch. Name the reactants in this chemical reaction

Magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. trial 1: trial 2: data mass of empty crucible with lid trial 1: 26.688 trial 2: 26.681 mass of mg metal, crucible, and lid trial 1: 26.994 trial: 2 26.985 mass of mgo, crucible, and lid trial 1: 27.188 trial 2: 27.180
