Since you have posted a question with multiple sub-parts , we will solve first three subparts for you . To get remaining sub-parts solved please repost the complete question and specify the sub-part to be solved.
Reaction in which both oxidation and reduction occurs is known as redox reaction .
Oxidation is reaction in which , either we gain oxygen or lose hydrogen .Other definition is when an element lose an electron or oxidation number increases , it has gone oxidation reaction .
Reduction is reaction in which , either we lose oxygen or gain hydrogen .Other definition is when an element gain an electron or oxidation number decreases , it has gone reduction reaction .
Element that help in oxidation of element is called oxidizing agent /oxidant .It itself undergo reduction. While the one that help in reduction is called reducing agent/reductant .It itself undergoes oxidation.
