Which of the following are true statements ?
For statements a) through d) use the reaction:
SiCl4 (l) + 2 Mg (s) → 2 MgCl2 (s) + Si (s)
a) Mg is the reducing agent
b) SiCl4 is the reducing agent.
c) Mg is reduced
d) SiCl4 (or Si in SiCl4) is reduced.
e) SiCl4 (l) + 2 H2O (l) → 4 HCl (aq) + SiO2 (s) is a redox reaction.
f) Al(OH)4- (aq) → AlO2- (aq) + 2 H2O (l) is a redox reaction.
