Civil Disobedience, Non-Co-operation, and Satyagraha were not done as constitutional methods . Always the public agitations to achieve social justice through the methods of the constitution. So, According to him the above agitations were called as “Grammar of anarchy”.

d. JawaharlalNehru

Ambedker had the rare gifts like unravelling the most complicated legal concepts. And also he had tactfulness, frankness and patience.

c.  a Symbol of revolt

He bought 32 boxes of books from London.

b. Mahatma Phule

The killing of small animals disturb the life cycle and food chain. 

For example: if we kill snakes, rodents that are eaten by snakes will increase in number and destroy the crop at mass level. In another case if we kill frogs then the number of insects that destroy our crops and are eaten by frogs will damage the crop. In nutshell killing of any animal leads to our own harm.

Babasaheb passed away in December 1956.

(a) Wild animals: When forests are cut, the natural habitat of the animals is destroyed. Without the natural habitat the animals are left with no place to live and breed. As a result of this many animals are at the verge of extinction. 

(b) Environment: Environment is adversely affected by deforestation as ecological balance is disturbed. Carbon dioxide is not absorbed by plants and it gets accumulated in the atmosphere to cause global warming which increases the temperature of earth and disturb water cycle. 

(c) Villages (Rural Areas): Deforestation leads to soil erosion and results in flash floods. This hampers agricultural activities and thus disturbs the people in rural areas. 

(d) Cities (Urban Areas): Deforestation in cities can increase the risk of many natural calamities such as floods and droughts in that area. 

(e) Earth: The whole earth is full of various ecosystems which together make the biosphere. Deforestation disturbs the balance in the biosphere. It disturbs climatic patterns. 

(f) The next generation: They will not be able to see wide variety of flora and fauna also not get clean and cool environment. They will have to breathe poisonous gas. Life would be very difficult for the next generation.

(a) If we go on cutting trees then: 

(i) Earth will lose its top fertile soil layer and get converted into desert. 

(ii) The ecological balance will get disturbed and floods and drought will become more frequent. 

(iii) Wildlife will also be affected. 

(b) The habitat of an animal provides it with necessities such as shelter, food, and protection. If the habitat of an animal is disturbed, then it will be forced to go to other places in search of food and shelter. The animal could get killed by other animals in this process. 

(c) If the top layer of soil is exposed, then it will gradually expose the lower layer of soil, which is hard and rocky in nature. This type of soil is less fertile as it contains less humus. Continued soil erosion will make the land barren or infertile.

c. Divide and Ruled

d.  Black Americ

The fourteenth amendment of the American cotitution gave freedom to the Block AmericAnswer:

Dr. Ambedkar made significant observations. The Constitution is a fundamental document. It defines the position and power of the three organs viz., the executive, the legislative and the Judiciary. It also defines the powers of the organs against the citizens. Its main purpose is not merely to create the organs but to limit their authority to check, otherwise, there will be tyranny or oppression.

Mahatma Phule was a devotee and worked for classless society and women’s upliftment.

1. A group of students marched into the principal’s office and stood there peacefully.

2. There was a lot of excitement at the time of the cricket team’s departure for the World Cup.

3. Though the light was dim, the old man went on walking on the road.

4. In winter, many birds migrate from the cold regions.

5. Dev could not control his pet dog and it bit a boy playing in the garden.

6. The teacher realized that the children were making an effort to complete the project on time.

After becoming Law Mfister and Lawmaker he was called as Doctor.

a. grammar of anarchy

Dr. Ambedkar had a clear perception of the three pillars of the state. He realised that; the Jurisdiction of each should be clear and not hampered legal bars. He had a sense of the importance of the role of citizens. According to him the constitution should define the position and powers of the three organs of the State-the executive, the Judiciary and the legislature.

The other notable members of the drafting committee were Alladi Krishnaswami Iyyar, K.M. Munshi and. Gopalaswami Ayyangar etc…

The opinion of Buddha regarding the last divisions are 

1. The noble and wholesome people and 

2. The ignoble and unwholesome people. 

The Tamil Poetess Awai said that 

1. The charitable who give and are superior 2. The misers who do not give and are inferior.

Della wanted to buy a gift for Jim and she had only $1.87 which was not sufficient to buy any gift. Hence she decided to sell her hair and buy a good gift with the money she would get.

2. on account of 

3. on the lookout for 

4. beggars description 

5. to attend to 

6. At last 

7. turned, inside out 

8. made for 

9. on the sly 

10. are looking for

The mention of a pier-glass between the windows of the room is one more example of O. Henry’s humour blended with pathos. A very thin and very agile person might, by observing his reflection in a rapid sequence of longitudinal strips, obtain a fairly accurate conception of his looks. Della, being slender, had mastered this art.

The other example is of Della’s gift. When Jim looks at Della’s gift, he just puts his hands under the back of his head and smiles. He tells Della to put away their Christmas presents for some time, as they were too nice to use just at that time.

We have been already told that Jim and Della are a loving couple. Even in their exigent condition, they desire to gift something to each other. Both keep their attempts to buy a gift a secret from each other. In order to gather the money needed to buy a gift, they sell the most precious things they possess. Though their gifts prove to be useless, they gain in love and satisfaction with each other.

An orbital can hold only two electrons.

The climax should have been the happiness and joy on the faces of Jim and Della when they see their gifts. It ends up as an anti-climax because though they had got what they coveted, neither of them could now use the gifts.

They would probably just feel that all the sacrifice was wasted. They would not have realized the deeper meaning of the story.

1. Name of the principle : Pauli’s exclusion principle.

2. No, two electrons in an orbital can have all four quantum numbers same. 

3. It says there is a chance to hold only 2 electrons, one rotates in clockwise direction (+1/2)other rotates in anticlock wise direction (-1/2)

The buyer can increase the value of a gift bought for someone very dear in the family by giving it with words of love and gratitude. He /She can also write something loving on a card and attach it to the gift.

The Magi visited Jesus after his birth to give gifts to honour him. The Magi wanted to celebrate their Christmas by exchanging gifts. They were the first people to give Christmas gifts.

Correct option is c. Vander waals forces

Argon is a monoatomic noble gas and in solid state these atoms are held together by Vander Waals forces.

3. Na₂SO₃ + 2HCl → 2NaCl + H₂O + SO2 

4. FeS + 2HCl → FeCl₂ + H₂S

A solution of hydrogen chloride in water; water being a covalent solvent ionizes aqueous solution of HCl shows acidic properties and is an electrolyte, whereas toluene is not; being not a polar solvent.

(a) HCI gas occurs in free state in gastric juices of mammals. 

(b) Due to difference in electronegativities of H and Cl ; The bond in HCl is a polar covalent.

Advantages of Detergents

• Synthetic detergents clean effectively and lather well even in hard water and salt water (sea water). There is no scum formation.

• Since detergents are the salts of strong acids they do not decompose in acidic medium. Thus detergents can effectively clean fabric even if the water is acidic.

• Synthetic detergents are more soluble in water than soaps.

• They have a stronger cleansing action than soaps.

• As detergents are derived from petroleum they save on natural vegetable oils, which are important as essential cooking medium.

Merits of the Long Form of the Periodic Table

• This classification is based on the most fundamental property of the

• Elements - the atomic number, so it is more accurate.

• With the atomic number as the basis of this classification, the position of isotopes in one place is justified.

• The electronic configuration determines the properties of the elements. The position of elements governed by this feature is useful in studying the properties of elements.

• The position of the elements, which were misfit on the basis of atomic mass is now justified on the basis of atomic number.

• The lanthanides and actinides have been placed separately due to their properties being different from other groups.

• The whole table is easy to remember and reproduce in terms of electronic configuration and properties of the elements.

Demerits of the Long Form of the Periodic Table

Although the long form of the period table has been able to help in systematic studying the elements to a great extent, it has some minor defects:

• Hydrogen resembles both the alkali metals and halogens. But it has been placed with the alkalis and with the halogens.

• The lanthanides and actinides have not been placed in the main body of the table.

Valency

Valency is the combining capacity of an element. For metals it is the number of electrons lost during chemical combination while for nonmetals it is the number of electrons gained during chemical combination.

When metals combine with hydrogen, they show a valency corresponding to group number, & nonmetals show a valency equal to (8 – group number).

Thus, valency of an element with respect to hydrogen increases from 1 to 4 and then falls from 4 to 1 across a period.

All elements when combining with oxygen can show a valency corresponding to group number.

For example, 

phosphorus forms phosphorus pentoxide (P₂O₅), where the valency of P is 5 & corresponds to its group number (V A). While combining with hydrogen, phosphorus forms phosphine (PH₃) where it shows a valency of 3 (8- group number)

Atomic Volume

It is defined as the volume occupied by one mole atoms of the element at its melting point, in solid state.

Variation along the Group – increases on moving down the group.

Variation along the period – decreases along the period, reaches a minimum in the middle and then starts increasing. Alkali metals have maximum atomic volume in a period.

Atomic Size and Atomic Radius

Atomic Radius – The distance between the centre of the nucleus and the outermost shell of an isolated atom.

Covalent radius of an element – half the internuclear distance between the two atoms of the element held by a single covalent bond.

Metallic radius of an element – half the internuclear distance between the two nearest metal atoms in a metallic crystal.

Atomic radii increases down the group and increases across the period.
