B) 2NaOH + Zn → Na₂  ZnO₂ + H₂ 

Bua lived in Delhi.

b. a joint family

Anjali was going to sleep on the couch in the hall after vacating her room.

After the grandparents went to her Bua’s house she felt lonely and the big happy family was changed to silent house. She felt the lack of love of her grandparents. She missed them.

b. Dada and Dadi

D)  2AgCl \(\overset{sunlight}\longrightarrow\) 2Ag + Cl₂

Ramesh stayed with an old couple Shyama Rao and Kamala.

To show his gratitude towards Shyama Rao and Kamalabai, he had given his house the name ‘SHYAMKAMAL’.

Anjali’s mother removed Anjali’s things from her cupboard.

d) there was a difficult terrain between the forest and the city.

Correct option is D) 2, 3

In reaction (ii), MgO + H₂O → Mg(OH)₂

MgO and water combined together to form a single product, i.e., magnesium hydroxide.

In reaction (iii), 4Al + 3O₂→ 2Al₂O₃

Aluminium combines with oxygen to form a single product. i.e., aluminum oxide

Hence, both are examples of combination reactions.

The lesson The Nuclear Test is all about the importance of the nuclear family. The advantages and the disadvantages of a small family is explained in the story. Anjali a school going girl and does not like her grandparents to Stay with her. But the father of Anjali wanted, his parents to stay in his house because his parents were old and feeling loneliness in the village, as there was no one to look after them.

Horse, bullock and elephants

The king wanted to make his palace special by setting the whole palace upon a single wooden column, a column carved from one of the biggest trees in his kingdom.

After her grandparents left, there was no one to talk to her. Her mother was again overworked with no time for anyone, or anybody. But most of all, the noise and bustle of one big happy family had faded into silence. The house, all eight hundred and fifty feet of compact space planning, suddenly looked too big. This made them nuclear family again.

1. House – Houses

8. Eye – eyes 

9. Table – Tables 

10. Piece – Pieces 

11. Company – companies 

12. Lorry – lorries

The tree-spirit went to the king and requested strangely that ‘Let me be felled in three parts. The king had never ever heard such desire to suffer the death stroke. The tree spirit went on explaining that dozens of young Sal trees have sprung from me and thrived in my generous shadow. If I was felled with one mighty storke, my weight would certainly crush all my children to death’.

1. The king sent his men to the forest to cut down and bring the mightiest tree. (True) 

2. Only elephants could be used to move the tree (False) 

3. The leaves of the Sal tree were concerned only about themselves. (False) 

4. The king was very pleased to change his mind at the tree’s first request. (False) 

5. The king decided that the column for the new palace should be built of stone (True)

The tree spirit described itself as the spirit of the sal tree. It said that it has been worshipped by the people of many village, for a thousand years, and never has anything but good come out to them. Birds, wild animals and people take shelter under its branches. It’s crown is made of waving greenery, and it has hundred strong arms. It has the heaviest and knottiest limbs.

C) displacement

It tells that Anjali realized the importance of ‘grandparents’ presence in the house. They helped and showed care towards her all these days. She wanted to have her grandparents again. Their being in the house made a tremendous change in her life. It would always make her busy with things.

It is really suitable title ‘The Nuclear Test’ to this lesson. It reflects the importance of a Joint family. In the absence of the grandparents, the family felt somewhat abandoned but after having the grandparents back, the things are very different. Joint family is the best family in my view.

In reaction (c), H₂ and O₂ are in gaseous state and the product formed that is water is in liquid state. This represents the correct state of the reactants and products

The correct option is(d) (ii) and (iii)

• A reaction in which two or more reactants react together to form a single product, is called a combination reaction. 
• In reaction (ii), MgO and H₂O combine to form Mg(OH)₂ and in reaction (iii), Al and O₂ combine to form Al₂O₃.
• Reaction (i) is decomposition and reaction(iv) is displacement reaction.

c) it gave the tree great strength, size and beauty

d) branch by branch

After the foresters had conveyed their decision to cut the mighty sal – tree. The tree – spirit within it was sure that it’s fall would crash all the little sal trees that had sprung up and thrived under – its protection. The tree – spirit ‘thought to itself that it does not care for itself but for the children’s sake, it requested the king to cut it in three parts, so that the young sat trees growing around it will not be crashed when it would fall to the ground. The tree was ready to suffer the stroke and endure the agony not once but thrice for the sake of its children. This shows the generous and protective nature of the mighty sal tree.

The foresters, at last, decided to cut a splendid sal tree which grew nearby the king’s palace. A tree – spirt, worshipped by the people of many villages was within it. So they brought garlands, lamps and music to offer them to the tree spirit and to warn him that he must leave his abode within seven days. The tree spirit heard and understood well enough what was about to happen. It remained quiet, then, all its leaves began to whisper, and his topmost branches bowed. The foresters went away satisfied that he had answered their plea.

Among the given metals, only aluminium has a stable +3 oxidation state. Aluminium reacts with acid to produce a metal salt and H₂ gas. For example: Al reacts with HCl to give AlCl₃ and H₂ gas. 

Reaction:

Al (M) + HCl (H⁺) → AlCl₃ (M³⁺) + H₂

Dilute sulphuric acid: dil. H₂SO₄ 

Iron sulphide: FeS 

Hydrogen sulphide: H₂S 

Ferrous sulphate: FeSO₄ 

The reaction involved can be written as: 

FeS + H₂SO₄→ FeSO₄ + H₂S 

We can see that there is the exchange of SO₄^2- and S^2- ions in the reactants. Thus it is a double displacement reaction.

The correct option is (c) 2H₂(g) + O₂(g) → 2H₂O(l) 

is the correction reaction as during formation of water both hydrogen and oxygen are in gaseous form and produces water in liquid form.

Correct option is B) 2 moles

Since the reaction involves the breaking down of a single reactant molecule into multiple products, it is a decomposition reaction. Moreover it involves the absorption of heat, so it is also an endothermic reaction.

The correct option is (d) Heating copper wire in presence of air at high temperature

When copper is heated in presence of air very slowly at high temperature, a layer of brown black copper oxide is formed which protect the copper from extensive corrosion.

Shyama Rao was a retired postmaster and my father’s friend. He gave me a place to stay in. Kamala Bai was so selfless that she would share her meals with me. I enjoyed the meals so much and felt like I was having these meals with my mother. As Dharwad was very famous for the Peda, Mr. Shyama Rao always brought pedals. They did not let me go hungry for a single day and treated me like their son. If I was late in paying my college fees, he would lend some money from Ills meager pension and help me out.
