Playing games along with studies in school is very important for the physical growth and balance of the children. It also develops in them qualities like cooperation and spirit of teamwork to work with each other.

The Assessment process should not be boring, or it should be on the basis of only one aspect. The teacher should be careful about using a variety of ways to collect information, about the students learning across scholastic and co-scholastic boundaries. Only scholastic areas should not be focused on assessment. It should also include co-scholastic areas.
Hence, the correct answer is, 'Using a variety of ways to collect information about the students learning across scholastic and co-scholastic boundaries.'

All exams must be conducted for the backward children. Emphasis must be paid on providing proper education to them so that they can easily face all examinations.

Inclusion as a philosophy or practice cannot be discussed meaningfully unless it is situated in the context of diversity across the members of the group, especially in the framework of inclusive education. 

Key Points

• Inclusive education means creating effective classrooms where the educational needs of all children are addressed irrespective of ability or disability.
• It implies all learners, young people - with or without disabilities being able to learn together through access to common pre-school provisions, schools, and community educational settings with an appropriate network of support services.
• Social inclusion refers to a process by which efforts are made to ensure equal opportunities for all, regardless of their background, be it money, class, ethnicity, gender, race, or whatever the index of diversity be, to enable full and active participation in all aspects of life, including civic, social, economic, and political activities, as well as participation in decision-making processes.
• Social inclusion can be approached as a goal, an objective, and a process. Its process affects almost all societal activities, and should therefore be approached from various dimensions.
• Hence, the effort for quality-based inclusive education for all should be a Child-centered, relevant, and justified process of learning in a social context so that is not affected by social barriers and get an equal opportunity to learn and develop in life.

​Thus, it is concluded that a Child-centered, relevant, and justified process of learning in a social context will be the effort for quality-based inclusive education for all.

Hint

• Sensitivity towards all the needs of the children comes under child-centered education. The teacher must take care and be sensitive towards the children.
• Improvement in self qualification and teaching methodology: Teacher will improve themselves and their methodologies to impart quality education to children. This is also a part of child-centered education.
• School should be complete with all the high technology instruments to impart quality, relevant and justified education to children.

One of the goals of education is to develop independent learning in students. However, at times, students might need a little push from the teacher in order to achieve that independence. Scaffolding is a technique that helps during such a scenario.

ZnO is an amphroteric oxide.

(a) In SbF₅ (expansion of octet from 5 to 10 and further to 12).
(b) NH₃, BF₃ both have complete octet. NH₃ is electron rich, donates lone pair to BF₃.
(c) AICI₃ is electron deficient, accepts lone pair from Cl^-.
(d) In SF₄, expansion of octet from 8 to 10 and further to 12.

Sol.    = 1 p and  = 2 for d.

 Now Cr has configuration

1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁵ 4s¹

Hence there are 12, p-electrons and 5, d-electrons

= 946 + 249 - 607 - 418 = 1195 - 1025 = 170 kJ mo^l-1 
Resonance energy = Observed heat of formation – calculated heat of formation 
= 82 -170 = 88 kJ mol^-1

Na₂[Fe(CN)₅NO] is Sodium nitroprusside.

It is pseudo first order reaction.

Product 1-Does not have any chiral carbon so only one product
Product 2-Two chiral centres so RR, RS and SR possible
Product 3-Two chiral centres so RR, RS and SR possible
Product 4-Two chiral centres but plane of symmetry exists, so only two isomers.

The minimum number of C atoms required for a hydrocarbon to exhibit optical isomerism = 7

F, O and N are electronegative elements. Thus, HF molecules are associated by intermolecules H-bonding giving it a liquid state and thus highest boiling point out of HF, HCl.HBr and HI.
Similarly, H₂O has highest boiling point, and NH₃ has highest boiling point.

environmental chemistry basically deals with the interrelationship between chemical species generated by human activities or naturally.

The presence of particulate matter in polluted air catalyses the oxidation of sulphur dioxide to sulphur trioxide. Oxides of Nitrogen: Di-nitrogen and di-oxygen are the main constituents of air. These gases do not react with each other at a normal temperature.

Total number of electrons = 16

Number of bonding electrons = 10, Number of anti-bonding electrons = 6,

• Sodium carbonate, Na₂CO₃, (washing soda) is the water-soluble sodium salt of carbonic acid, well-known domestically for its everyday use as a water softener.
• Pure sodium carbonate is a white, odorless powder that is hygroscopic (absorbs moisture from the air).
• It has a strongly alkaline taste and forms a moderately basic solution in water.

This alkaline earth hydride is a colourless solid that is insoluble in solvents that do not decompose it. Unlike the ionically bonded hydrides of the heavier Group 2 elements, beryllium hydride is covalently bonded (three-center two-electron bond).

In CH₃ - CH₂ - Cl, the carbon marked with asterisk has the greatest positive charge due to high electronegativity of Cl.

From the sizes of octahedral and tetrahedral voids, it is clear that the atoms occupying these voids will not touch each other as we have along body diagonal of FCC.

K_sp  = S (S–X) = 11 × 10^–6 × 10^–6
= 1.1 × 10–11

O=C=O<−>−O−C+=O

Newland's Law of Octaves arranged elements in groups of seven, resembling musical octaves. However, this law did not leave room for the discovery of noble gases, which have very different properties compared to the elements in Newland's groups.
