• Zinc

• Sodium

• Potassium

If carbon can remove oxygen from a metal oxide, it means carbon is ___________ reactive than the metal.

• more

• less

During reaction between hydrogen and iron(III) oxide, observation as below is obtained:

Iron(III) oxide burns brightly. Reddish brown powder turns shiny grey.

What does this mean?

• Iron(III) oxide is produced. Hydrogen oxidised iron to iron(III) oxide.

• Iron is produced. Hydrogen reduces iron(III) oxide to iron.

• Hydrogen does not reduce iron(III) oxide.

• Iron(III) oxide does not reduce hydrogen.
