Hot conc. H2SO4 acts as moderately strong oxidizing agent. It oxidizes both metals and non-metals. Which of the following elements is oxidized by conc. H2SO4 into two gaseous products?
C+2H2SO4→CO2+2SO2+2H2O
Carbon (C) is the elements oxidized by conc. H2SO4 to give two gaseous products which are CO2,SO2.
Hence option C is correct.
