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.
Another example of oxidation-reduction reaction is the tarnishing of silver in the presence of atmospheric oxygen gas. Similar example is corrosion of iron in the presence of oxygen to form ferrous oxide and ferric oxide which are deposited on the metal surface and called as rust.
