An aqueous solution with sulfur 10 g/L at the rate is 100 L/min and an organic compound with no sulfur at the rate 50 L/min were put into an extraction machine and produced an aqueous solution with sulfur 1 g/L, what is the amount of sulfur in the organic compound after extraction?

Which component of sulfur attacks the vanadium catalyst?

In the manufacture of H2SO4, vanadium catalyst as compared to platinum catalyst

Severe corrosion of metals occurred when coupled with platinum is due to the higher current density for hydrogen evolution but not due to the reversible potential of the platinum-platinum ion electrode.

Platinum catalyst used in the earlier days of sulphuric acid manufacture by contact process suffers from the drawback like

Which one of the following catalysts used in contact process before the using of vanadium pentoxide?

Pharmacists recently conducted a study with respect to the reasons their customers purchased eye drops to soothe eye dryness. Dry eyes were more frequently experienced by customers who wore contact lenses than by custorners who did not wear contact lenses. The pharmacists concluded that wearing contact lenses, by itself, can cause contact wearers to have dry eyes.
