Answer 1

Answer:

redox reaction

..................oxidation + reduction

Answer 2

Answer:

combination reaction and redox reaction.

Explanation:

2mg +o2----> 2mgo is a combination as well as redox reaction.

Combination reaction is a reaction where two or more elements or compounds (reactants) combine to form a single compound (product). Such reactions may be represented by equations of the following form: (X + Y → XY).

The synthesis of magnesium oxide, MgO , is a redox reaction in which oxygen gas oxidizes magnesium metal, while being reduced in the process. Each magnesium atom loses two electrons, so two magnesium atoms will lose a total of four electrons.
