The mass of carbon anode consumed (giving only carbon dioxide) in the production of 270 kg of aluminium metal from bauxite by Hall process is:

Answer»

180 kg
270 kg
540 kg
90 kg

Solution :`2Al_2O_3 + 3C to 3CO_2 + 4Al`
`4 xx 27` g of Al are OBTAINED when carbon ANODE consumed= `12 xx 3g`
270 g of the Al are obtained when carbon anodeconsumed ` = (12 xx 3)/(4 xx 27)xx 270 = 90 kg `
