In the synthesis reaction, the oxygen causes the aluminum to lose electrons, oxidizing it, as it now has an Oxidation number of +3. Since the oxygen is what causes the Oxidation of aluminum, it is the oxidizing agent.
Answer:
Gravitational Potential Energy to Kinetic Energy. When an object with Gravitational Potential Energy starts to fall, its G PE is transferred into Kinetic Energy .
Explanation:
The further the object falls, the less G PE it has and the more K E it has. When the object hits the ground, all of its G PE has been transferred into K E.
