The reaction is given as
Fe2O3 (s)+ 3CO(g)--->3CO2(g)+ 2Fe(s)
No.of moles=mass in gram/molar mass
As for Fe mole =156.2g/55.847=2.7969~2.797
The ratio b/w CO and Fe is 3:2
Moles of CO needed= 2.797x3/2=4.1955
Mass of CO needed= 4.195mol x 28.01g/mol= 117.515g
PbCr04 + P4O10
Hope this helps!
C is the answer the moon has less mass than earth
2Al +3CuSO4=Al2 (SO4)3+3Cu.
is the balanced equation.
HOPE IT HELPS YOU '_'
