Aluminium can be manufactured from the electrolysis of a molten mixture of aluminium oxide and cryolite. In this process, which electrode must be continually replaced

The carbon anode

Explanation:

The carbon anode is continually replaced because it burns off as carbon IV oxide gas by reacting with the oxygen had produced at the anode.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
