the number of moles of electrons transfered by `1` mol of reductant :-

In the reaction 8Al+3Fe_(3)O_(4)rarr 4Al_(2)O_(3)+9Fe the number of electrons transferred from the reductant to the oxidant is

In the reaction Al + Fe_(3) O_(4) rarr Al_(2) O_(3) + Fe- what is the total no. of electrons transferred during the change -

Is the reaction, 2Al+3Fe^(2+) hArr 2Al^(3+) + 2Fe possible ?

In the reaction 4Fe + 3O_(2) to 2Fe_(2)O_(3) . Fe acts as an oxidizing agent.

Using the DeltaG^(@) for the reactions {:(C+O_(2)rarrCO_(2),DeltaG^(@)=-395kJ//"mole"),(2Al(l)+3//2O_(2)rarrAl_(2)O_(3)(s),DeltaG^(@)=-1269kJ //"mole"),(Al_(2)O_(3)(s)rarrAl_(2)O_(3)("melt"),DeltaG^(@)=16kJ //"mole"):} What is the EMF for the cell reaction 2Al_(2)O_(3)("melt")+3Crarr4Al(l)+3CO_(2)(g) The number of electrons involved in the reaction is 12.
