In fact, weâre not spending enough on food stamps. 1  The average monthly food stamp benefit per person is only $133.85, or less than $1.50 per person, per meal. 2  Between 2009-2011 the purchasing power of food stamps declined by about 7%, or $47/month for a family of four, due to inflation in the cost of food.
Instead, we will use the following definitions: 1  Oxidation means the addition of oxygen to a molecule or the removal of hydrogen from a molecule.  Reduction means the addition of hydrogen to a molecule or the removal of oxygen from a molecule.
Electron-rich metal centers with open coordination sites (or the ability to form them) undergo oxidative additions with dihydrogen gas. The actual addition step is concerted, as we might expect from the dull H 2 molecule! However, before the addition step, some interesting gymnastics are going on.
