Sulfur is a bright yellow solid at room temperature. It is one of the components in gunpowder, matches, and fireworks. It is added to rubber to make it tougher (vulcanization) and to topical ointments for the treatment of skin disorders. a. What is the molecular formula? b. How many electrons and protons are there in an atom of sulfur? c. Two atoms of sulfur combine with two atoms of chlorine. Is this compound a molecule? What is its name and formula? d. How many neutrons are there in the isotope S-36? e. The naturally occurring isotopes of sulfur, their atomic masses, and abundances are: S-32 :31.97207 amu – 94.93% S-33 : 32.97146 amu – 0.76 % S- 34: 33.96786 amu – 4.29 % S- 36 :35.96708 amu – 0.02 % What is the average atomic mass for sulfur? Show the detailed solution. f. How many atoms are there in 12.55 grams of elemental sulfur (S) ? g. What is the mass of a billion atoms of sulfur? h. Sulfur can combine with oxygen in many different ways. Give five examples of that compound and write the corresponding name.
