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:
to preserve the integrity of the wildlife refuge, ecosystems and the endangered species.
Explanation:
A national park service manages
Answer:
It comes from the chemical reaction of The wax and the gas because the wax is made up of carbon-based chemicals so the gas and carbon make the candle light =)
Explanation:
Multiplying the subscripts within the empirical formula by this number gives you the molecular formula H2O2.
