In one group, including M 2 UO 4 (M=Li, Na, K) and MUO 4 (M=Ca, Sr) there are six additional oxygen atoms. Taking calcium uranate, CaUO 4 , as an example, the six oxygen atoms are arranged as a flattened octahedron , flattened along the 3-fold symmetry axis of the octahedron which also runs through the O-U-O axis (local point group D 3d at the ...

The psalm could also be interpreted as a "dialogue", as the priests and Levites who served in the Temple are enjoined in verses 1 and 2 to spend their time during the night watch in acts of devotion rather than small talk; and in verse 3 these devotees are urged to pray for the one who enjoined them in verse 1 – either the high priest or a ...
Ammonium diuranate or (ADU) ((NH 4) 2 U 2 O 7), is one of the intermediate chemical forms of uranium produced during yellowcake production. The name "yellowcake" originally given to this bright yellow salt, now applies to mixtures of uranium oxides which are actually hardly ever yellow.
1% and 2% uranyl acetate solutions are used as an indicator, and a titrant in stronger concentrations in analytical chemistry, as it forms an insoluble salt with sodium (the vast majority of sodium salts are water-soluble). Uranyl acetate solutions show evidence of being sensitive to light, especially UV, and will precipitate if exposed.
Uranyl nitrate is a water-soluble yellow uranium salt with the formula UO 2 (NO 3) 2 · n H 2 O.The hexa-, tri-, and dihydrates are known. [3] The compound is mainly of interest because it is an intermediate in the preparation of nuclear fuels.
The uranyl ion is always associated with other ligands. The most common arrangement is for the so-called equatorial ligands to lie in a plane perpendicular to the O–U–O line and passing through the uranium atom. With four ligands, as in [UO 2 Cl 4] 2−, the uranium has a distorted octahedral environment. In many cases more than four ...
The apostates also wrote about Jews eating a lot of garlic on Christmas Eve to ward off the demon Jesus, as well as Jewish children being hesitant to use the latrine on Christmas Eve from the fear of Jesus reaching out and pulling them in. [4] The observance of Nittel Nacht was popularized by the Baal Shem Tov in the 18th century. [2]
