Libra (Toni Braxton album)

Libra is the sixth studio album by American singer Toni Braxton. It was released on September 27, 2005 by Blackground Records. The album's title is a reference to Braxton's astrological sign, Libra.

The album debuted at number four on the Billboard 200 and at number two on the Top R&B/Hip-Hop Albums, selling 114,000 copies in its first week. Only three singles were released from the album, and due to lack of promotion from Blackground Records, Braxton's then-record label, all of them failed to chart on the Billboard Hot 100, subsequently causing Braxton to terminate her contract with the label. Nonetheless, as a result of the European success of "The Time of Our Lives"—Braxton's collaboration with the group Il Divo, which served as the official 2006 FIFA World Cup theme song—, German label Edel Records re-released the album in continental Europe in late June 2006 including "The Time of Our Lives" as well as a brand-new cover art. Previously, the regular European edition of the album had included three bonus tracks: "Suddenly", "I Hate You", and "Long Way Home". The song "Stupid", which is track 8 of the album, has briefly appeared in the 2005 Tyler Perry film Diary of a Mad Black Woman.

Dioxygen difluoride

Dioxygen difluoride is a compound of fluorine and oxygen with the molecular formula O
2F
2. It exists as an orange solid that melts into a red liquid at −163 °C (110 K). It is an extremely strong oxidant and decomposes into oxygen and fluorine even at −160 °C (113 K) at a rate of 4% per day: its lifetime at room temperature is thus extremely short. Dioxygen difluoride reacts with nearly every chemical it encounters – even ordinary ice – leading to its onomatopoeic nickname "FOOF" (a play on its chemical structure).

The material has no practical applications, but has been of theoretical interest. One laboratory's use of it was the synthesis of plutonium hexafluoride at unprecedentedly low temperatures, which was significant because previous methods for its preparation needed temperatures so high that the plutonium hexafluoride created would rapidly decompose.

Preparation

Dioxygen difluoride can be obtained by subjecting a 1:1 mixture of gaseous fluorine and oxygen at low pressure (7–17 mmHg is optimal) to an electric discharge of 25–30 mA at 2.1–2.4 kV. A similar method was used for the first synthesis by Otto Ruff in 1933. Another synthesis involves mixing O
2 and F
2 in a stainless steel vessel cooled to −196 °C (77.1 K), followed by exposing the elements to 6987480652946100000♠3 MeV bremsstrahlung for several hours. A third method requires heating a mix of fluorine and oxygen to 700 °C (1,292 °F), and then rapidly cooling it using liquid oxygen. All of these methods involve synthesis according to the equation:
