The Turkish Straits (made up of the Straits of Bosphorus and the Dardanelles) and the Sea of Marmara also mark the border between the continents of Europe and Asia. Most of Turkey (97%) is located in Asia. Most of the people in Turkey are Muslims, and the country's official language is Turkish. The Turks first migrated to the area in the 11th century. Beginning in the 13th century, the entire area was part of the vast Ottoman Empire, which finally collapsed after being defeated in World War I.
Sulfur: compounds information This section lists some binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and some other compounds of sulfur. For each compound, a formal oxidation number for sulfur is given, but the usefulness of this number is limited for p-block elements in particular.
These drugs have no relationship to sulfonamide allergy. However sulfhydryl containing drugs can cause unrelated adverse skin reactions such as a rash or pemphigus (a rare autoimmune blistering disease). Sulfates are also commonly found in soaps and cosmetics; allergies to sulfates are extremely rare. Sulfites are chemicals used as preservatives in food and drugs, e.g. sulfur dioxide and sodium sulfite. Allergy to sulfite preservatives can cause anaphylaxis, other rashes, asthma, seizures and death. People with asthma are at higher risk of sulfite allergy.
