41) 102.50 = 0.512 *(6.22/M)/0.076
M = 40
4 FeCl3 (s) + 3 O2 (g) -> 2 Fe2O3 (s) + 6Cl2 (g)
b) redox reaction
c) 26.5/162.2 = 0.162 moles of fecl3
and one mole of fecl3 =react with 3 moles of HCl
moles of HCl required = 0.162*3 =0.490 mol
V HCl = 0.492/2 = 0.082 L = 82 ml
Regarding any doubt plz let me know
what kind of redox reaction is it?
the oxidation state of Fe is +3 in both FeCl3 as well as Fe2O3
but Cl- going to oxidation to Cl2
therefor oxidation is occuring
