The exactly half-filled and fully filled orbitals have greater stability than other configurations. The reason for their stability are symmetry and exchange energy.
(a) Symmetry: The half-filled and fully-filled orbitals are more symmetrical than any other configuration and symmetry leads to greater stability.
(b) Exchange Energy: The electrons present in the different orbitals of the same sub-shell can exchange their positions. Each such exchange leads to the decrease in energy known asExchange Energy. Greater the number of exchanges, greater the exchange energy and hence greater the stability. As the number of exchanges that take place in the half-filled and fully-filled orbitals is maximum, thus exchange energy is maximum and hence maximum stability.

Energy (E) of one photon = E = hv
where h = 6.626 {tex}\times{/tex} 10-34 Js.
{tex}\nu{/tex} = 5 {tex}\times{/tex} 1014 s-1
{tex}\therefore E = \left( 6.626 \times 10 ^ { - 34 } \times 5 \times 10 ^ { 14 } \right){/tex}
{tex}= 3.313 \times 10 ^ { - 19 } J{/tex}
Energy of 1 mole of photon{tex}= \left( 3.313 \times 10 ^ { - 19 } J \right) \times \left( 6.022 \times 10 ^ { 23 } \mathrm { mol } ^ { - 1 } \right){/tex}= 1995.1 kJmol-1

Main sources of the secondary data can be classified into two groups :
1. Published sources :
a) Government Publications
(b) Semi-government Publications
(c) International Publications
(d) Private Publications
(e) Research Publications
2. Unpublished sources : Secondary Data can be obtained from unpublished sources, because all statistical material is not always published. Studies made by research institutions, scholars etc. can be important sources of secondary data.

A relation from a set A to another set B by definition is a subset of the Cartesian product of the two sets A and B i.e.( A x B ) . If A has 2 elements and B has 3 elements then (A x B ) has (2 x 3 ) = 6 elements in it.
Therefore no. of subsets of (A x B) = 2^(6) = 64 ; that are the required numbers of relations from A to B.

Herbarium is “a collection of plant specimens which have been dried and pressed and arranged in the sequence of an accepted classifications”. It forms a store house for future use. The preparation of Herbarium involves following steps :
(1) Collection of Specimens : It is a field work. For collection one has to get information about the area, habitat, season and the time of collection. There is a requirement of digger for digging roots, scissors for cutting twigs, knife for woody twigs and a pole with a hook for collection.
(2) Drying and Pressing : After collection, the plants are dried up by keeping them between the folds of old newspapers. The plants, after (hying, are pressed up by a set of two broads straps.
(3) Mounting : The dried specimens are pasted on the herbarium sheets of standard size (29 X 41 cm). The specimens are fixed on the sheets by applying glue or adhesive.
The specimens are sprayed with fungicides like 01% solution of mercuric chloride and pesticides like DDT, naphthalene to check fungal growth and insects infections.
(4) Labelling : Labelling should be done with mounting. It should bear the botanical name, family, locality, data of collection with the habit of the plant specimen. The name of the collector or the person should also be given.
(5) Storage : The sheets are arranged according to classification. They are stored in disinfected metallic cupboards. The information about the collected specimens-is compiled and published in the form of a book.

tan(13π/12)
= tan(4π/3 - π/4),
= [tan(4π/3) - tan(π/4)]/[1 + tan(4π/3)tan(π/4)]
= (-1 + √3)/(1 + √3)
= -(1 - √3)/(1 + √3)
= -(1 - √3)^2/[(1 + √3)(1 - √3)],
= -(1 - √3)^2/(1 - 3)
= (1/2)(1 - √3)^2
= (1/2)(1 - 2√3 + 3)
= (1/2)(4 - 2√3)
= 2 - √3.

We know, Atomic mass of H = 1.001 u
Atomic mass of N = 14.01 u
Atomic mass of O = 16.0 u
Hence, molar mass of HNO3 will be:
{tex}( 1 \times 1.001 ) + ( 1 \times 14.01 ) + ( 3 \times 16.0 ){/tex}= 63.01 u

Hydrocarbon undergoes combustion to form carbon dioxide and water.
Molecular mass of carbon dioxide = 44 g
Mass of Carbon in 4.4 gm of carbon dioxide = {tex}\frac{12}{44} \times 4.4{/tex} = 1.2 g
Mass of Hydrogen in 2.7 gm of water = {tex}\frac{2}{18} \times 2.7{/tex} = 0.3 g
Therefore,
Total mass of Hydrogen and Carbon = (1.2 +.3)g = 1.5 g
This is the same mass before combustion.

Here f (x) = (x - a)(x - b)
{tex}\therefore \;f{\text{'}}(x) = \frac{d}{{dx}}(x - a)(x - b){/tex}
{tex} = (x - a)\frac{d}{{dx}}(x - b) + (x - b)\frac{d}{{dx}}(x - a){/tex}
= (x - a) × 1 + (x - b) × 1
= x - a + x - b = 2x - a - b
