[6] [7] The formula is sometimes given in its hydrous crystalline form as 2NaOCl·10H 2 O. [17] The Cl–O bond length in the pentahydrate is 1.686 Å. [9] The transparent, light greenish-yellow, orthorhombic [18] [19] crystals contain 44% NaOCl by weight and melt at 25–27 °C. The compound decomposes rapidly at room temperature, so it must ...
The partial sums of the series 1 + 2 + 3 + 4 + 5 + 6 + ⋯ are 1, 3, 6, 10, 15, etc.The nth partial sum is given by a simple formula: = = (+). This equation was known ...
The final digit of a triangular number is 0, 1, 3, 5, 6, or 8, and thus such numbers never end in 2, 4, 7, or 9. A final 3 must be preceded by a 0 or 5; a final 8 must be preceded by a 2 or 7. In base 10, the digital root of a nonzero triangular number is always 1, 3, 6, or 9. Hence, every triangular number is either divisible by three or has a ...

"25 or 6 to 4" is a song written by American musician Robert Lamm, one of the founding members of the band Chicago. It was recorded in August 1969 for their second album, Chicago , with Peter Cetera on lead vocals, [ 1 ] and released as a single in June 1970.
An example of the difference is the empirical formula for glucose, which is CH 2 O (ratio 1:2:1), while its molecular formula is C 6 H 12 O 6 (number of atoms 6:12:6). For water, both formulae are H 2 O. A molecular formula provides more information about a molecule than its empirical formula, but is more difficult to establish.
New York may finally update a formula used to disperse $24.9 billion to school districts- 10% of the state budget. A study is beginning.
