Boron sulphide B 2 S 3 can be obtained by the direct union of the two elements at a white heat or from the tri-iodide and sulphur at 44 0 C., but is most conveniently prepared by heating a mixture of the trioxide and carbon in a stream of carbon bisulphide vapour. It has strong affinity for water. The medical case on display on the ground floor of this spectacular three-storey medical collection shows the jawbone of one such sufferer, removed to save the patient from the potentially terminal effects of exposure. The cool, greenish glow of phosphorus is caused by its reaction with oxygen, but it doesnt take much for this reaction to accelerate and develop into a fire, as the 17th century chemist Nicolas Lemery found out: After some experiments made one day at my house upon the phosphorus, a little piece of it being left negligently upon the table in my chamber, the maid making the bed took it up in the bedclothes she had put on the table, not seeing the little piece. The percent composition of the compound is: H = (2g/18g) x 100 = 11.1% O = (16g/18g) x 100 = 88.9% Percent composition can be calculated the chemical formula of a compound, or it can be determined experimentally.
