equipment used priestley in experiments on gases



some oxides, of weakly electropositive metals decompose when heated high enough temperature. classical example decomposition of mercuric oxide give oxygen , mercury metal. reaction used joseph priestley prepare samples of gaseous oxygen first time.
when water heated on 2000 °c, small percentage of decompose oh, monoatomic oxygen, monotomic hydrogen, o2, , h2.
the compound highest known decomposition temperature carbon monoxide @ ≈3870 °c (≈7000 °f)..

decomposition of nitrates, nitrites , ammonium compounds

ammonium dichromate on heating yields nitrogen, water , chromium(iii) oxide.
ammonium nitrate on strong heating yields dinitrogen oxide ( laughing gas ) , water.
ammonium nitrite on heating yields nitrogen gas , water.
barium azide on heating yields barium metal , nitrogen gas.
sodium nitrate on heating yields sodium nitrite , oxygen gas.
organic compounds tertiary amines on heating undergo hoffmann elimination , yield secondary amines , alkenes.

the crystal court ids tower ground the owners of capella tower (formerly first bank place) , architects behind design stated rose 774 feet (236 m) tall upon completion in 1992. however, height had been increased due engineering need, according tom o mara, 1 of construction managers @ time of capella tower construction. there ventilation ducts near roof required 14 more inches (36 cm) of height. construction team added 10 inches (25 cm) that, bringing building total of 776 feet 0 inches (236.52 m). in years following completion, actual height became known published in almanacs , other listings of building height. owners of capella tower hesitant claim building taller ids, , deferred honor more well-known structure. area journalists reported on sale of ids center john buck company in 2004 , death of designer philip johnson in 2005, came face-to-face fact roof of tower 1 foot lower neighbor. emporis.com restored ids center first-place status in city in fe...
