CHAPTER-7 The p-Block Elements Block
... Carbon suboxide (C3O2) is a colourless gas at room temperature. However, it readily polymerises to coloured solids. Carbon does not show inert pair effect. Carbons differ from other elements of the group 14, because of its smaller size, high electro negativity, catenation and non-availability ...

... In a typical UV/oxidation system, reagents are injected and mixed using metering pumps and an in-line static mixer. The contaminated water then flows sequentially through one or more UV reactors, where treatment occurs. Pretreatment, such as solids removal, pH adjustment and oil and grease removal, ...

Oxidation Number Rules
... 3. The oxidation numbers of some common atoms are: a. Fluorine, the most electronegative element, is -1 in all fluorine containing compounds. b. In most oxygen containing compounds oxygen is -2. In peroxides (i.e. H2O2) each oxygen has an oxidation number of -1. In the compound OF2, the oxygen atom ...
