Answer:
Oxygen is oxidizing gent and itself get reduced while lead is reducing agent and itself get oxidize.
Explanation:
Chemical equation with oxidation state:
O⁰₂(s) + Pb⁰ (s) → Pb⁺⁴O₂⁻²(s)
Oxidizing agent:
Oxidizing agents, oxidize the other substance and itself get reduced. They can be identify by just looking the oxidation state. If oxidation state is decreased on the right side it means substance gain the electron and get reduced.
Reducing agent:
Reducing agents, reduce the other substance and itself get oxidize. They can be identify by just looking the oxidation state. If oxidation state is increased on the right side it means substance lose the electron and oxidation state increased.
In given chemical equation, oxygen and lead were in neutral form they react and form lead dioxide. In this product oxygen is oxidizing gent and itself get reduced and oxidation state change from 0 to -2 while lead is reducing agent, itself get oxidize and oxidation state change from o to +4.

Answer: The results agree with the law of conservation of mass
Explanation:
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. On the reactant side, the total mass of reactants is 14.3g and the total product masses is also 14.3g. That implies that no mass was !most in the reaction. The sum of masses on the left hand side corresponds with sum of masses on the right hand side of the reaction equation.
