§ Mr. Hastingsasked the Paymaster-General what percentage of sulphur compounds are contained in average samples of petrol, paraffin used for burning and diesel oil, respectively; and what changes take place in these sulphur compounds on complete combustion.
§ Sir I. HorobinThe percentages of sulphur are approximately 0.05, 0.05 and 0.5, respectively. Complete combustion converts the sulphur almost entirely into sulphur dioxide.
