It can be reduced to the corresponding alcohol with hydride reducing agents. [7] Asymmetric alkylation gives the chiral α-hydroxyethylferrocene. [ 8 ] Dioxane derivatives, obtainable from 1,3-diols and the aldehyde, sustain ortho lithiation .
The 12.7 cm/50 Type 3 naval gun was a medium-caliber naval gun of the Imperial Japanese Navy used during World War II. It was the standard weapon for Japanese destroyers between 1928 and 1944 (except the Akizuki and Matsu classes). It has been credited as a true dual-purpose gun, but this was more a nominal capability than real, as its bag ...
Suppose the radius of the sphere is and the length of the cylinder (or the tunnel) is .. By the Pythagorean theorem, the radius of the cylinder is . Finding the measurements of the ring that is the horizontal cross-section.
The CH 2 peak will be split into a doublet by the CH peak—with one peak at 1 ppm + 3.5 Hz and one at 1 ppm − 3.5 Hz (total splitting or coupling constant is 7 Hz). In consequence the CH peak at 2.5 ppm will be split twice by each proton from the CH 2 .

5 V USB power, used for example to charge a cell phone or a digital camera. [18] Also one of the most common digital circuit supply voltages for both TTL and CMOS technologies. 6 V A common voltage for medium-size electric lanterns. [19] A voltage for older electric systems of automobiles. Deca-10 1: 12 V Typical car battery [20] Hecto-10 2: ...
The ideal gas equation can be rearranged to give an expression for the molar volume of an ideal gas: = = Hence, for a given temperature and pressure, the molar volume is the same for all ideal gases and is based on the gas constant: R = 8.314 462 618 153 24 m 3 ⋅Pa⋅K −1 ⋅mol −1, or about 8.205 736 608 095 96 × 10 −5 m 3 ⋅atm⋅K ...
front cover G1 1930. This is the Group G series List of the United States military vehicles by (Ordnance) supply catalog designation, – one of the alpha-numeric "standard nomenclature lists" (SNL) that were part of the overall list of the United States Army weapons by supply catalog designation, a supply catalog that was used by the United States Army Ordnance Department / Ordnance Corps as ...
