Oxidación

The video explains the concept of oxidation and reduction in chemical reactions, highlighting that electrons are lost for one substance to oxidize while another is reduced. It uses the reaction between lead oxide and carbon as an example, where carbon is oxidized and lead oxide is reduced.

What is generally lost during a chemical reaction?

• Protons

• Neutrons

• Electrons

• Atoms

In a chemical reaction, if one substance is oxidized, what must happen to another substance?

• It must evaporate

• It must be oxidized as well

• It must be reduced

• It must be neutralized

What happens to carbon when it reacts with lead oxide?

• It evaporates

• It is oxidized

• It remains unchanged

• It is reduced

What is the product formed when lead oxide reacts with carbon?

• Carbon dioxide

• Lead carbonate

• Carbon monoxide

• Lead sulfate

During the reaction of lead oxide with carbon, what happens to lead oxide?

• It remains unchanged

• It evaporates

• It is reduced

• It is oxidized
