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.
Oxygen's most common oxidation state is â2, and the oxidation state â1 is also relatively common. With hydrogen it forms water and hydrogen peroxide. Organic oxygen compounds are ubiquitous in organic chemistry. Sulfur's oxidation states are â2, +2, +4, and +6. Sulfur-containing analogs of oxygen compounds often have the prefix thio-.
