Question

Name the substance oxidised, substance reduced, oxidising and reducing agents. also balance the equation wherever necessary.
a) H2O + F -----------------> HF + HOF
b) Fe2O3 +CO ---------------> Fe + CO2
c) H2 + 02 -----------------> H2O
d) Al + Fe2O3 ----------------> Al2O3 + Fe

Answer 1

b) Fe2o3 is reduced to Fe and it is oxidising agent
CO is oxidised to CO2 and it is reducing agent
c) H2 is oxidised and it is reducing agent
O2 is reduced and it is oxidising agent
d) Al is oxidised and it is reducing agent
Fe2O3 is reduced and it is oxidising agent
a) F is reduced and it is oxidising agent
H2O is oxidised and it is reducing agent




Balanced equation
a) H2O + 2F ——————————> HF + HOF
b) Fe2O3 + 3CO ————————-> 2Fe + 3CO2
c) 2H2 + O2 ———————————> 2H2O
d) 2Al + Fe2O3 ——————————> Al2O3 + 2Fe
