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 simple terms, oxidation is the gain of oxygen. We can say that magnesium is oxidised as it becomes magnesium oxide when it is burned in the air. Oxidation can also be considered as part of a pair of changes that go at the same time: red uction and ox idation (redox).
