oxides of most nonmetals combine with water to form .

Hydrogen combines with non-metals, to give the respective hydrides. With oxygen Hydrogen burns in oxygen to form water. Instead of igniting the mixture, if a small quantity of well divided platinum is added to the mixture of the two gases, they instantly..

Oxides - The elements of group 15 combine with oxygen either directly or indirectly to form oxides. The important oxides of group 15 elements along with their oxidation states are listed in table. Thus, it is nitrogen, which forms..

An example of a transfer of two electrons (Fig. 3.3) ..

>Metals occupy the groups on the left of periodic table and are largely classified as alkali metals (group IA) alkaline earth metals (group IIA) and transition metals (elements between group IIA and IIIA) Metals and non-metals combine to form electrovalent or ionic com..

Oxides are binary compounds of oxygen with another element, e.g., CO 2 , SO 2 , CaO, CO, ZnO, BaO 2 , H 2 O, etc. These are termed as oxides because here, oxygen is in combination..

The elements of group 15 combine with oxygen either directly or indirectly to form oxides. The important oxides of group 15 elements along with their oxidation states are listed in tabl..

The elements of group 16 form a variety of oxides. Some of these are given below: Element Oxides S SO SO 2 SO 3 S 2 O 7 Se - SeO 2 SeO 3 - Te TeO TeO 2 TeO 3 - Po Po..

Oxidation - Oxidation of alcohols involves the formation of a carbon oxygen double bond with cleavage of an O-H and C-H bond..

When dry chlorine is passed through molten sulphur it combines with sulphur to form vapors of sulphur monochloride S 2 Cl 2 . When these vapors are condensed, they form a red liquid (Fig.14.11)...

With hot concentrated nitric acid, non-metals are oxidized to their oxide while the acid itself gets reduced to nitrogen dioxide. In all the reactions described below, the nascent oxygen is released during the thermal decomposition of the acid, which oxidizes..
