Magnesium reacts with oxygen as follows: 2 Mg(s) + O2(g) + 2 MgO(s) Suppose a crucible with magnesium in it is placed on a balance (with a barrier in between to protect the balance from the heat). That's balance #1. The magnesium and balance #1 is placed in an atmosphere of pure oxygen in a sealed container, and the container is placed on balance #2. After the reaction,...
