GENERAL CHARACTERSTICS OF ETHERS :
PHYSICAL PROPERTIES :
Physical properties of ether
Crushing and Grinding of the ore:- the ores occur in nature as huge lumps. They are broken to small pieces with the help of crushers and grinders. The p
Question 1: Find the principal and general solutions of the equation tan x=3
General Physiochemical Properties:-
The general physiochemical properties of 1st row transition elements are discussed as follows:
Extraction of Elements:- As metals exist in oxidized form and non metals in reduced form, therefore the methods of extractions of metals and non-metals from t
Extraction of Iron:-
Iron is usually extracted from the oxide ore i.e. hematite (Fe2O3). It involves the following steps:
Extraction of Copper:-
In the Ellingham Diagram Cu2O curve lie above the C, CO and CO, CO2 curves hence can be easily reduce
Extraction of Copper from Low Grade Ore and Scraps:-
Copper is extracted by hydrometallurgy from low grade ore. Copper is extracted by leaching it
Metallurgy:- As we have discussed that metal exist in oxidized form. therefore, metals occur in the earth crust in the form of their compounds such as oxides,
Extraction of Aluminium:-
Alumina (Al2O3) has very high melting Pt (2323k) and fused Alumina (Al2O3) i
Modes of occurrence of elements:- Depending upon the reactivity of the elements, they generally occur in two states:- (1) Native State (2) Combined state.
Theory of smelting (Reduction Process):- Thermodynamics and Ellingham explains the reduction of FeO to Fe. One of the main reduction steps is:
Electrochemical Principal of Metallurgy (Electrometallurgy):-
We know that ΔG0 = - nFE0
If the value of E
Extraction of Zinc:-
The reduction of Zinc oxide is carried out by using Coke. It is clear from Ellingham Diagram that reduction of ZnO with C occ
Question 1: In the matrix A = 2
Inner Transition Elements: (f-block elements) – Lanhanoides and Actinoides
The inner transition elements are divided into two categories Lant
Modern periodic law:- It is based upon Moseley’s saying that physical and chemical properties of elements are function of their atomic number.
Functional groups: It may be defined as an atom or group of atoms joined in a specific manner which is responsible for the characteristic chemical p
PROTEINS
Proteins are the complex organic substances which are the basis of protoplasm and are found in all the living organisms. In general proteins are the polyme

Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are the two types of nucleic acids found in l
General Properties of Actinides:-
Oxidation State of Actinides:- Unlike Lanthanoids, Actinioids show a variable of O.S. It
