acf 3 + 2 nh 3 + h 2 o → acof + 2 nh 4 f Actinium trichloride is obtained by reacting actinium hydroxide or oxalate with carbon tetrachloride vapors at temperatures above 960 °C (1,760 °F). Similarly to the oxyfluoride, actinium oxychloride can be prepared by hydrolyzing actinium trichloride with ammonium hydroxide at 1,000 °C (1,830 °F).
For aviation purposes, where it is common to add times in an already complicated environment, time tracking is simplified by recording decimal fractions of hours. For instance, instead of adding 1:36 to 2:36, getting 3:72 and converting it to 4:12, one would add 1.6 to 2.6 and get 4.2 hours. [19]
npf 3 + 1 ⁄ 2 o 2 + hf → npf 4 + 1 ⁄ 2 h 2 o (400°c) Later, NpF 4 was obtained directly by heating NpO 2 to various temperatures in mixtures of either hydrogen fluoride or pure fluorine gas. NpF 5 is much more difficult to form and most known preparation methods involve reacting NpF 4 or NpF 6 compounds with various other fluoride compounds.

Octane isomers such as n-octane and 2,3,3-trimethylpentane have an octane rating of -20 and 106.1, respectively (RON measurement). [89] The large differences between the octane ratings for the isomers show that the compound octane itself is clearly not the only factor that determines octane ratings, especially for commercial fuels consist of a ...
