SOLVED: A biochemist who is studying the properties of certain sulfur (S)-containing compounds in the body wonders whether trace amounts of another nonmetallic element might have similar behavior. To which element should she turn her attention? (a) F (b) As (c) Se (d) Cr (e) P

The elements oxygen and sulfur have similar chemical properties because they both have six electrons in their outermost electron shells. Indeed, both elements form molecules with two hydrogen atoms, water (H2 O) and hydrogen sulfide (H2 S). Surprisingly, at room temperature, water is a liquid, yet H2 S is a gas, despite sulfur being much larger and heavier than oxygen. Explain why this might be the case. | Numerade

Estimation of Sulphur Phophorous and Oxygen - Organic Chemistry: Some Basic Principals, class 11 Video Lecture

SOLVED:The percentage of sulphur in an organic compound whose amount of 0.32 g produces 0.233  g of BaSO4 (Atomic weight of Ba=137,  S=32 ) is (a) 1.0 (b) 10.0 (c) 25.3 (d) 32.1

SOLVED:How would you isolate a thermophilic chemolithotroph that uses sulfur compounds as a source of energy and electrons? What changes in the incubation system would be needed to isolate bacteria using sulfur compounds in anaerobic respiration? How would you tell which process is taking place through an analysis of the sulfur molecules present in the spent medium?
