Reacción redox

The video explains the chemical reaction where iron oxide is heated with carbon, resulting in the reduction of iron oxide to pure iron and the oxidation of carbon to carbon dioxide. It further defines oxidation as the loss of electrons and reduction as the gain of electrons.

What happens to iron oxide when it is heated with carbon?

• It evaporates.

• It is reduced to form pure iron.

• It remains unchanged.

• It turns into carbon dioxide.

During the reaction, what does carbon become?

• Carbonic acid

• Pure carbon

• Carbon dioxide

• Carbon monoxide

Which of the following best describes oxidation?

• Loss of electrons

• Loss of protons

• Gain of electrons

• Gain of protons

What is the general result of a reduction process?

• Gain of electrons

• Loss of electrons

• Loss of protons

• Gain of protons

In a redox reaction, what typically happens to the oxidizing agent?

• It gains electrons.

• It loses protons.

• It loses electrons.

• It gains protons.
