State of the System and State Functions - State of the system implies the conditions of its existence. In order to understand it, let H 2 O be considered as a chemical system. H 2 O can exist in three physical states; ice, water and steam depending upon the c..

State of the system implies the conditions of its existence. In order to understand it, let H 2 O be considered as a chemical system. H 2 O can exist in three physical states; ice, water and steam depending upon the conditions of temperature and pressur..

Matter occurs in four states: Solid, Liquid, Gas and Plas..

A property whose values depend on only the state of the system and not on the path by which the change from initial to final state is brought about is called state function. The change in the value of the state functions depends only upon the initial and fin..

Lanthanides exhibit different oxidation states like +2, +3 and +4. Among these +3 is the most stable oxidation state. The elements that attain stable electronic configuration by losing 2 or 4 electrons exhibit +2 and +4 oxidation states. Example: Europium and ytterbiu..

The first row transition elements show variable oxidation states. Zn is an exception among them. As it has fully filled d-orbital, it exhibits only +2 oxidation state. The oxidation states of first row transition metals are shown belo..

Of the three states of matter, the gaseous state is the simplest and shows greatest uniformity in behaviour. Gases show almost similar behaviour irrespective of their chemical natur..

Introduction - The classification of matter into three different states, namely solid, liquid and gaseous state is termed as the physical classification of matter. Most properties of solid, liquid and gases that can be observed with our sense organs are called as 'macroscopic' p..

Halogens have only one electron less than the next noble gas. Therefore, they can get the noble gas configuration either by gaining one electron to form uninegative ion, X - , or by sharing electrons with other atoms. Thus, they show an oxidation of state of l or + 1. Since fluorine is th..

The atoms of these elements have three valence electrons, two in s-subshell and one in the p-subshell (ns 2 np 1 ). Therefore, all these elements can show maximum of +3 oxidation state. The common oxidation states, observed for group 13 elements are +3 and + l as shown below. ..
