The presence of 4 H was deduced by detecting the emitted protons. It decays by neutron emission into 3 H with a half-life of 139(10) ys (or 1.39(10) × 10 −22 s). In the 1955 satirical novel The Mouse That Roared, the name quadium was given to the 4 H that powered the Q-bomb that the Duchy of Grand Fenwick captured from the United States.
3.7 m – leg span of a Japanese spider crab; 3.7 m – length of a southern elephant seal, the largest living pinniped; 5 m – length of an elephant; 5.2 m – height of a giraffe [122] 5.5 m – height of a Baluchitherium, the largest land mammal ever lived; 6.5 m – wingspan of Argentavis, the largest flying bird known
The extremes of the meantone systems encountered in historical practice are the Pythagorean tuning, where the whole tone corresponds to 9:8, i.e. (3:2) 2 / 2 , the mean of the major third (3:2) 4 / 4 , and the fifth (3:2) is not tempered; and the 1 ⁄ 3-comma meantone, where the fifth is tempered to the extent that three ...
(1.096 77 × 10 7 m −1 for hydrogen and 1.097 37 × 10 7 m −1 for heavy metals). [ 5 ] [ 6 ] The wavelength will always be positive because n′ is defined as the lower level and so is less than n .
In Earth's atmosphere, the ratio of 3 He to 4 He is 1.343(13) × 10 −6. [5] However, the isotopic abundance of helium varies greatly depending on its origin. In the Local Interstellar Cloud , the proportion of 3 He to 4 He is 1.62(29) × 10 −4 , [ 6 ] which is ~121 times higher than in Earth's atmosphere.
hexasilane Si 6 H 14 or H 3 Si−SiH 2 −SiH 2 −SiH 2 −SiH 2 −SiH 3, 6 silicon atoms and 14 hydrogen atoms, analogous to hexane; Silanes are named by adding the suffix-silane to the appropriate numerical multiplier prefix. Hence, disilane, Si 2 H 6; trisilane Si 3 H 8; tetrasilane Si 4 H 10; pentasilane Si 5 H 12; etc.
For cyanogen N≡C−C≡N and acetylene H−C≡C−H (n = 4) the same analysis yields f = 19 and predicts c P,m = 10.5 R = 87.3 J⋅K −1 ⋅mol −1. A molecule with n atoms that is rigid and not linear has 3 translation modes and 3 non-trivial rotation modes, hence only 3 n − 6 deformation modes.
