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.
The Reaction of Oxygen with Sulfur Dioxide to make Sulfur Trioxide. Sulfur dioxide is made by reacting sulfur with oxygen. Sulfur dioxide can be made to react with more oxygen to make sulfur trioxide. This is another example of oxidation. The reaction is reversible (shown by the arrow). The forward reaction (from left to right) is exothermic. This is the balanced chemical equation for the reaction of sulfur dioxide with oxygen. sulfur dioxide + oxygen sulfur trioxide.
