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.
In the course of this reaction, CuO is reduced to copper metal. Thus, H2 is the reducing agent in this reaction, and CuO acts as an oxidizing agent. An important feature of oxidation-reduction reactions can be recognized by examining what happens to the copper in this pair of reactions.
