Idon't understand my oxidation homework!

So first you would need to have understand how to assign oxidation numbers to elements. Once you understand the rules, assign each element their correct oxidation number on both the reactant side and the products. If the element's oxidation number increases when moving from a reactant to a product, then that element is being oxidized. If the element's oxidation number decreases when moving from a reactant to a product, then that element is being reduced.
