A Levels Chemistry

Zirconium, Zr, proton number 40, is a metal which is used in corrosion-resistant alloys.
Zirconium metal is extracted from the oxide ZrO2 by the following sequence of reactions.
reaction 1
ZrO2 + 2C12 + 2C → ZrClą + 20o
reaction 2 ZrCl4 + 2Mg → Zr + 2M9C12
Which statements about this extraction process are correct?
1
Carbon in reaction 1 behaves as a reducing agent.
2
Magnesium in reaction 2 behaves as a reducing agent.
3
Chlorine in reaction 1 behaves as a reducing agent.
