The concrete operational stage is defined as the stage of child development in which a child starts performing mental operations and starts thinking logically. This stage occurs in children at the age of 7 – 11 years.

Predicting, Questioning, Clarifying and Summarizing are the components of reciprocal teaching activity.

"Readiness for learning" refers to the cognitive level of students in the learning continuum. Readiness for learning means how a person seeks out knowledge on their own. This trait in students stimulates maximum achievement. Motivation, inspiration, or the dreams to accomplish a goal helps a lot to achieve this readiness for learning in life.
Hence, the correct answer is, 'Present cognitive level of students in the learning continuum.'

Ankit, a 12 years boy, is not enrolled in school due to some circumstances. He has requisite computational skills and intends to enroll in a school to learn. Ankit has an aptitude for learning.

• An aptitude test is designed to assess what a person is capable of doing or to predict what a person is able to learn or do given the right education and instruction.
• It represents a person's level of competency to perform a certain type of task.
• Aptitude can be defined as someone’s natural ability to do something.
• Teaching aptitude, hence, refers to an individual’s innate ability in teaching.
• It can also be defined as the ability of a person to teach, once they are given the necessary training.

Therefore, we can conclude that Ankit, a 12 years boy, is not enrolled in a school due to some circumstances. He has requisite computational skills and intends to enroll in a school to learn. Ankit has an aptitude for learning.

(a) Zn is oxidised to Zn²⁺ in complex

(b) Au⁺ is reduced to Au — True
(c) Au (s) is displaced
(d) Since, it is a spontaneous reaction ΔG° < 0

Ozonolysis breaks the double bond and oxidizes that carbon. To solve these questions, when the reactants are asked, just remove the carbonyl oxygen from the products and join the resulting compounds using a double bond. 

Due to lanthanide contraction, Ag and Au have nearly same size.

In halogen-exchange (Finkelstein reaction), reactivity is determined by solubility of Na X formed in acetone. Lower the solubility of Na X in acetone, easier the reaction. NaCI is less soluble than NaBr in acetone.

NH2 has lp of electron which reacts with AlCl3 or other catalyst that we add to form anilium ion.

Metal ion is Fe³⁺ which have 5 unpaired electrons.

Water has a hybridization of sp³. In a water molecule oxygen has two lone pairs and two bonded hydrogens. Its structure is V in shape and has a bent structure. Water has a chemical formula of H₂O.

Lactose intolerance is the inability to break down a type of natural sugar called lactose. Lactose is commonly found in dairy products, such as milk and yogurt. A person becomes lactose intolerant when his or her small intestine stops making enough of the enzyme lactase to digest and break down the lactose.

Plutonium (Z = 94) have [Rn] 5f⁶6d⁰7s² configuration and show oxidation state upto +7.

The correct answer is Option D.

Because C₄H₉NH₂ is primary amine and can form hydrogen bonding more than secondary amine (C₂H₅)₂NH and tertiary amine C₂H₅N(CH₃)₂ . More hydrogen bonding  leads to strong bonding between the molecules, hence increases the boiling point.

In this reaction, a CO group is converted to CH_2​ group.

This can be achieved by Wolff-Kishner reduction which uses reagent NH₂​NH₂​, OH⁻ (hydrazine in alkaline medium).

Clemmensen reduction (Zn(Hg)/HCl) cannot be used as in presence of HCl, the alcohol may undergo dehydration.

Hydrogen peroxide is used as a bleaching agent, disinfectant, source of power, in the restoration of old paintings in which lead oxide is used as a white paint, antiseptic and germicide. It is not used in teardrops.

The correct answer is Option A.
In a dichromate dianion structure, the negative charge can be on any O attached to Cr, therefore all Cr - O are equivalent. Also have Cr - O - Cr bond.

Decomposition of N₂O₅ is 1st order reaction.

Rate of reaction is independent of concentration of reactant.

Both are bent shape molecule.
