In condition of living a lonely fife, it would not be possible to develop socialization in the person. He/she will feel isolated and in condition of ill-health there will be inconvenience and the society won’t develop.

Answer is : (a) A family

Following are the two important benefits of family in a child’s life 

1. A child learns the traditions of the society and courtesy from the family. 

2. The lesson of living together along with harmony with others is also obtained from family.

The society is like our body. Just as all the body organs are important for our body and they all mutually complete the body, in the same manner, a society gets complete by the cooperation of all the individuals living in the society. If every individual starts living separately in isolation, then the society will segregate. It is important for the development of the society that the individuals should work all together in coordination and understand the irrespective responsibilities.

Every member of the society performs his/her respective work according to his/her interest and capability. Potter, blacksmith, goldsmith, tailor- all make goods which are useful for the society. Some people do jobs, while others do business. Teachers, doctors and engineers- all extend their services to the society. Police, administration and judiciary perform their role in maintenance of law and order in the society. In this manner, with the cooperation of all the people, our lives become happy. All the people contribute in the welfare of the society through mutual cooperation and mutual dependence.

Aim: 

To observe the saprotrophic nutrition in bread mould. 

What you need: 

Piece of bread, water, a container and a hand lens. 

What to do: 

Take a piece of Bread, in a container. Sprinkle some water and close the container. Open the container after few days and observe. (Use mask and gloves while doing this activity). 

What do you see: 

You will see cotton-like threads spread on the piece of bread and bread size is decreased. 

What do you learn: 

These thread-like structures are some sort of plants called Fungi. They don’t have chlorophyll so they obtain their food from dead and decaying matter.

B) Berzelius

Aim : 

To know the process of tooth decay. 

What you need : 

Marbles, dilute hydrochloric acid and test tube. 

What to do: 

Put a few small pieces of marble in dilute hydrochloric acid. Examine after awhile. What do you see : Acid reacts with marble and dissolves it. 

What do you learn : 

The enamel, which is a calcium compound, reacts with acid and gets destroyed in the same way a marble reacts with hydrochloric acid. 

When food remains stuck in teeth, bacteria feed on them. As a result, lactic acid is produced, which causes the destruction of enamel.

i) Conductor 

ii) Lubricant

(a) Uses of graphite:

1. For making the electrodes of electric furnaces.

2. For making crucibles for melting metals due to its high melting points.

(i) Butanone 

(ii) 2-Propanol 

(iii) Methanoic acid 

(iv) Methyl ethanoate

An ‘atom’ or ‘a group of atoms’ which makes a carbon compound (or organic compound) reactive and decides its properties (or functions) is called a functional group. The alcohol group, -OH, present in ethanol, C₂H₅OH, is an example of a functional group.

Homologous series is a series of organic compounds which have same functional group and similar chemical properties. Each member of this series is differ by —CH₂— in its molecular formula and 14 u in its molecular mass.

C₂H₆O (C₂H₅OH) and CH₄O (CH₃OH) belong to same homologous series.

Liquid X is ethanoic acid; it belongs to homologous series of carboxylic acids. Methanoic acid is another member of this homologous series.

 The answer is (d) C₄H₈

General formula for C₄H₈ is C_nH_2n and for other option it is C_nH_2n+2

ANSWER

A, B & C are all saturated hydrocarbons with the general formula: Cn​H2n+2​, whereas C4​H8​ is an alkene with general formula Cn​H2n​

Option D is correct.

Uses of graphite in day to day life : 

1. Pencil lead. 

2. Lubricant.

The answer is (c) (ii) and (iv)

Option (ii and (iv) having double and triple bonds, hence they are unsaturated hydrocarbons.

Cleavage is a property of splitting of crystals of some minerals in certain directions to produce a flat, even surface.

The various micelles present in water do not come together to form a precipitate as each micelle repels the other because of the ion-ion repulsion.

The answer is (d)

Diamond is a bad conductor of heat due to lack of free electrons.

Mark the longest chain of the given compound. If no carbon atoms are remaining after marking the chain, then the compound is not branched. If one or more carbon atoms are not marked in the longest chain, then they are said to be branches.

1. Allotropy is a property shown by the elements.

2. The property of an element to exist in two or more physical forms having more or less similar chemical properties but different physical properties is called allotropy.

3. The different forms of the element are called allotropes and are formed due to the difference in the arrangement of atoms. 

4. Example for allotropes : Allotropes of carbon.

Allotropes of carbon are classified into two types. They are 

1) Amorphous forms, 

2) Crystalline forms. 

3) Amorphous forms of carbon: Coal, coke, wood, charcoal, animal charcoal, lampblack, gas carbon, petroleum coke, sugar charcoal.

4) Crystalline forms of carbon : Diamond, graphite and buckminsterfullerene.

The property of an element to exist in two or more different forms due to the difference in their atomic arrangement is called “Allotropy” and the different forms are called allotropes.

5%–8% acetic acid in water

Unsaturated hydrocarbons are compounds of carbon and hydrogen which contain double bonds and/or triple bonds.
