AWES TGT Chemistry Mock Test - 1 - AWES TGT/PGT MCQ

Pradip Kumar Das, Chairman and Managing Director, Indian Renewable Energy Development Agency Limited (IREDA) participated in the 26th edition of the World Energy Congress held in Rotterdam, Netherlands. He also said that India ranks fourth globally in renewable energy installed capacity.      

IIT Bombay is ranked 45th globally in engineering according to the QS World University Rankings 2024, highlighting its excellence in the field and its leading position in South Asia.

The triarchic theory of intelligence is also called the three forms of intelligence. Based on this theory, research on human intelligence take a more cognitive approach. 
Sternberg explained only three types of intelligence: Componential or analytical sub theory, Experiential or creative sub theory, and Contextual or practical sub theory. 
Hence, the correct answer is, 'Social.'

The term 'Curriculum' within the field of education refers to the overall program of the varsity which students experience on a day-to-day basis. It is a planned sequence of instruction in terms of educator's and school's instructional goals. as a gaggle of learning goals. It is attached across grades that outline the intended mathematics content and process goals at particular points in time throughout the K–12 school program.
Hence, the correct answer is, 'Overall programme of the school which students experience on a day-to-day basis.'

The process of socialization includes communicating with another person or a group of people. It involves actively listening to the other person and also effectively reverting the other person.

According to Piaget's theory, children actively construct their understanding of the world through their experiences and interactions with the environment.

To have confidence that a test is valid, and thus the inferences we make based on the test scores are valid, three kinds of validity evidence are:

Construct- It is the extent to which the content of the test matches the instructional objectives.

Criterion- It is the extent to which scores on the test are in agreement with or predict an external criterion.

Content- It is the extent to which an assessment corresponds to other variables, as predicted by some rationale or theory.

For claiming credit for discovering 104^th element, the Americans named it Rutherfordium and the Soviets named it Kurchatovium. While it’s named Unnilquadium as per IUPAC nomenclature. Neptunium is the 93^rd element.

When we go down in a group shell increase and size increase and due to large size of atom electron can easily be removed. Thats option is C.

By Fajans' rule,
Smaller the size of cation, larger the size of anion.
Larger the charge ord-electrons present, then larger the polarising power of cation and larger the covalent nature and smaller the solubility in water.

Cu²⁺ due to shielding effect causes more screening than Zn²⁺.
Thus, polarising power of Na⁺ <Zn²⁺ < Cu²⁺ hence, ionic nature and solubility in water is in order
CuS < ZnS < Na₂S

• The periodic table of today owes its development to two chemists namely the Russian chemist Dmitri Mendeleev and the German chemist J. Lother Meyer.
• In 1869, they independently proposed that when the elements are arranged in the increasing order of their atomic weights, similarities in both physical and chemical properties appear at regular intervals.

On changing temperature, solvent (H₂O) is vaporised or condensed. Thus, volume of solution and solvent changes. Thus, any concentration factor dependent on volume is affected by change in temperature.
(a) Molarity = Mole/Litre (Volume dependent)
(b) Molality = Moles of solute/kg of solvent (weight dependent)
(c) Mole fraction = n_i/n_total(unitless)
(d) Weight fraction = w_i/w_total (unitless)

 2-bromomethyl-2-methyl-1-butanol: The bromine substitution occurs at the carbon bonded to oxygen but not at a chiral carbon. Thus option b satisfies the condition.

Molarity is temperature dependent. In the formula of molarity, you have L of solution. Volume is temperature-dependent. It varies with changing temperature. Because of this, molarity changes if the temp changes. 

∆H_Vap = 30kJ/mol and ∆S = 75 J/K
∆G = ∆H - T∆S
At eqm, ∆G = 0
Therefore, ∆H = T∆S
Or T = 30×10³/75 = 400 K

When chlorine and Ethane are taken with chlorine in excess only then we have more than one product like chloroethane, dichloroethane, trichloroethane etc. To avoid this we should take Ethane in excess because when we will take it then in excess then we will have only single time chlorination and we will get monochloroethane.

[Co(NH₃)₄CI₂]⁺ exhibits geometrical isomerism.
cis-[Co(en)₂CI₂]⁺ because of the absence of symmetry elements exhibit optical isomerism.
[Co(NH₃)₅(NO₂)]CI₂ because of the presence of ambidentate (NO₂) ligand exhibit linkage isomerism. [Co(NH₃)₆][Cr(CN₎6] exhibits coordination isomerism because here, cation and anion both are complex.

(i) → (s), (ii) →(p), (iii) → (t), (iv) → (r)

Suppose x m. mole NaOH was added

Strength of H-bonding depends on the electronegativity of the atom which follows the order: F > O > N .
Strength of H-bond is in the order:
H……. F > H…….. O > H…….. N
But each H₂O molecule is linked to 4 other H₂O molecules through H-bonds whereas each HF molecule is linked only to two other HF molecules.
Hence, correct decreasing order of the boiling points is H_zO > HF > NH₃.

Molecularity is defined as the number of molecules, atoms, or radicals that must collide simultaneously in order for the reaction to take place. It is always a natural number and cannot be negative.

Because isotones means the same number of neutron, So, from the question, option c is right, number of neutron in k is,39-19= 20,and,the number of neutron in ca is also 40-20=20 so it is isotones. 

75mL of M/5HCl + 25mL of M/5 NaOH 
Meq of HCl = 15 (∴ Mol. wt. and Eq. wt. of HCl or NaOH are same) 
Meq of NaOH = 5 Hence, in solution 10meq of HCl remains in 100mL solution. 
So, concentration of HCl in mixture = 10/100M = M/10 
In M/10 HCl, [H⁺] = 10^-1 M
pH = -log[H⁺] = -log10^-1 = 1

In physisorption no chemical reaction, only physical interactions hence, not specific.

Hydrogen peroxide’s chemical formula is H₂O₂ and it was discovered by J.L. Thenard in 1818. It is an important compound used in the treatment of pollution control treatment of Industrial and domestic effluents.

Vander waal forces are weak force of attractions, responsible for physisorption, as no chemical reaction taking place here.

Alpha rays as the least penetrating, followed by beta rays, followed by gamma rays as the most penetrating. 

2- pentanone is a methyl ketone. It undergoes haloform reaction with iodine in presence of sodium hydroxide, to form yellow precipitate of iodoform. 3- pentanone is not a methyl ketone. It does not undergo haloform reaction. Hence, 3- pentanone and 2- pentanone can be distinguished by reaction with iodine in presence of NaOH.

All these are soluble in water due to intermolecular H-bonding.

Only electronegativity of the given 4 decreases down the group whilst all the others increase or stay the same down the group.
