Oxides of group

Phosphorus(V) oxide reacts with a 2-3 molar equivalent of tetrachloromethane in a sealed tube over 48 h at 200-210 C to furnish a small quantity of COClj [850b,850c]. 

The reactions of tetrachloromethane with sulfur(VI) oxide have been discussed in Section 5.2.1.1. Phosgene has been detected in the synthesis of TeCl from TeOj and CCl, [1103a].

When cut by a knife, the exposed surface of an alkali metal or alkaline earth metal quickly turns into an oxide. These elements do not occur in nature as free metals. Instead, they react with many other elements to form white or grey water-soluble salts. With some exceptions, the oxides of group 1 elements have the formula M2O, their hydrides are MH, and their halides are MX (for example, NaCI). The oxides of group 2 elements have the formula MO, their hydrides are MH2, and their halides are MX2, for example, CaCh.

III and V elements. It was to be expected that americium would behave as a typical actinide element—i.e., that the majority of the ternary oxides to be expected contain Am (III). This assumption is based upon the analogous behavior of Ce02, PreOn, and Tb407 found in reactions with oxides of group V elements as well as upon the excellent thermal stability and the high lattice symmetry of compounds like and...

Oxides of Group I and II metals are base anhydrides, obtained by removing water from the corresponding hydroxides. Calcium oxide, CaO, is the base anhydride of calcium hydroxide, Ca(OH)2- The removal of water from Ca(OH)2 is the reverse of the addition of water to the oxide ...
