Zirconium perchlorate as cold as possible. Zirconium perchlorate is very hydroscopic forming hydrates, and it is hydrolysed by water to yield zirconyl perchlorate, ZrO(ClO). Zirconium perchlorate reacts with vaseline, methyl nitrate or acetonitrile. Zirconium perchlorate is inert towards carbon tetrachloride, chloroform, and dimethylformamide. Zirconium perchlorate reacts with benzene at 20°C, but at -10°C crystals of Zr(ClO)•CH are deposited. Zirconium perchlorate has solid state transition around 45°C, a melting point between 95.5 and 96.0°C and a decomposition point starting around 120°C. The zirconyl perchlorate formed in the heat decomposition, itself decomposes around 290°C to form zirconia, chlorine and oxygen. In the gas phase
Basque grammar rule which assigns focus to an element in pre-verbal position. The affirmative use of "ba-" (not to confused with the homophonous subordinating prefix meaning 'if') is normally used with synthetic finite forms, thus also "John badator" or "Badator John" 'John is coming' (as opposed to "John dator" " 'John" is coming'), "Badu dirua" (or in western Basque "Badauka dirua") 'She has money'. In most varieties of Basque, affirmative "ba-" is not so used with compound tenses or compound verbs, however. To place a compound verb form (or its affirmation) in focus, it may be enough to place the main sentence
