EMRS PGT Chemistry Mock Test - 6 - EMRS MCQ

The pattern followed is:

Hence, the correct answer is "K21".

The logic follows here is :-

From the given words we can understand that it is a process of construction or a materials.

Planning → Designing → Implementation → Manufacturing → Production 

So, logical and meaningful order is 4 - 1 - 5 - 2 - 3

Thus, the correct answer is "4 - 1 - 5 - 2 - 3".

Given statements: K > M < L = Z = O < P.

Conclusions:

I. P < Z → False (As, L = Z = O < P → P > Z).

II. M = Z → False ( M < L = Z → M < Z and L = Z).

Hence, "Neither Conclusion I nor II correct".

The logic follows here is :

Sum of place values of alphabets of the given word = Given number.

MONK → M + O + N + K = 13 + 15 + 14 + 11 = 53.

Similarly,

TUTOR → T + U + T + O + R = 20 + 21 + 20 + 15 + 18 = 94.

Hence, the correct answer is "94".

Hence. the person will be allowed to appear in the interview.

The meaning of synonym is Similar.

Similarly;

The meaning of Opposite is Adverse.

Hence, "Adverse" is the correct answer.

The elements of "s" and "p" blocks except "d" group elements are called as representative elements. Their outer shells are not completely filled with electrons. The elements get the nearest inert gas configuration by losing or gaining or sharing of electrons. 

Correct Answer is A.

∆H_r is called both enthalpy of combustion of hydrogen as well as enthalpy of formation of water.For the enthalpy of combustion of hydrogen, the reason is that 1 mole of Hydrogen is burnt in its pure state. For the formation of water, the reason is that 1 mole of water is formed from its constituent elements.

Volume decreased

i.e p increased

no.of moles reactant more

I₂ gets reduce to I⁻ while  H₂O₂ get oxidize to O₂

The correct answer is option A
2.03x 10^-4
The given equation is :-
 N2​(g)+3H2​(g) ⇌ 2NH_3​(g)
Initial moles : 1             3         0
At eqm ;       (1−x)    (3−3x)   (2x)               
(let)
Total moles of equation
 =1 − x + 3 − 3x + 2x = (4−2x)
Now, X(NH_3​) = 
⇒ 2x = 2 − x
⇒ 3x = 2 ⇒ x = 0.66 = 
32​
Now, at equation, moles of N₂​= 1/3, moles of NH_3​ = 4/3
             moles of H2 ​ =3 − 2 = 1

 

We have ∆G = ∆H - T∆S
For spontaneous reaction ∆G<0 and vice versa,
∆G at 80° C:-
3213 - (80+273)8.73 = 141.9 kJ mol-1
As it comes positive, the conversion of rhombic and monoclinic is non- spontaneous at 80° C.In other words, rhombic is more stable than monoclinic at this temperature.
∆G at 110° C:-
3213 - (110+273)8.73 = -119.1 kJ mol-1
As it comes positive, the conversion of rhombic and monoclinic is spontaneous at 110° C.In other words, rhombic is less stable than monoclinic at this temperature.

The correct answer is Option A.

Total pressure =290 mm
Vapour pressure of propyl alcohol =200 mm
Mole fraction of ethyl alcohol = 0.6
Mol fraction of propyl alcohol =1− 0.6 = 0.4
 
PT = P⁰_A × χ_A + P⁰_B × (1−χ_A)
290 = 200 × 0.4 + P^o_B × 0.6
0.6 × P⁰B = 290 − 80
P⁰B = 350 mm

The correct answer is Option D.
 
In presence of catalyst, 
E_(forward) = 80kJ/mol  and, 
E_(reverse) = 100kJ/mol.
 
Therefore, H_(reaction) =E_(reverse)−E_(forward)
=100−80
=20kJ/mol. 

In diamond, carbon atoms are joined together by strong covalent bonds tetrahedrally which makes it an atomic crystal. 

Hence, the correct answer is Atoms. 

• 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.

In benzene, benzoic acid forms dimer by intermolecular H-bonding.

Thus, osmotic pressure

Thus, solutions are not isotonic, (a) is incorrect.
III has maximum osmotic pressure, thus hypertonic of l, II and IV, (b) is correct.
IV has minimum osmotic pressure, thus hypotonic of I, II and III. Thus, (c) is correct.
II is hypotonic of III but hypertonic of I and IV, thus (d) Is correct.

Total number of electrons = 16

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

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

Valency is defined as the number of electrons in the outermost shell of an element . As the last shell(third shell) has one electron in it the valency of sodium(Na) is 1 or +1 as it looses that electron to form a cation and achieve noble gas configuration.

Sodium has 11 electrons: its atomic number is 11, so it has 11 protons; atoms are neutral, so this means sodium also has 11 electrons.

Rate of reaction can be measured in terms of Rate of disappearance of reactant or rate of apperance of product.

Learning takes place by comparing previous knowledge and experience with the present learning experience through thinking and activities. Learning is a universal skill seen in all species. Thinking and Learning are two interwoven activities that help to develop knowledge, critical thinking, and creative thinking.

Key Points

•  Despite the addition of more specialized disciplines and subject instructors, experiential learning within each subject and investigations of relationships among different subjects will be encouraged and highlighted.
• Experiential learning will be implemented at all levels, with investigations of the connections between various disciplines as well as hands-on learning, education that incorporates the arts and sports, and pedagogy centered on telling stories, among others, as normal practices within each subject.
• Classroom activities will change to competency-based learning and teaching to address the achievement gap in learning outcomes. Additionally, the assessment instruments—including assessment "as," "of," and "for" learning—will be in line with the learning objectives, skills, and attitudes that are listed for each subject in a given class.
• Each subject's curriculum will be edited down to the fundamentals in order to allow room for critical thinking and more all-encompassing, inquiry-based, discovery-based, discussion-based, and analysis-based learning.

Hence, National Education Policy 2020 proposes that experiential learning should be encouraged to promote critical thinking. 

The National Education Policy (NEP) was approved by the Union Cabinet in July 2020 and aims to implement various improvements to the Indian educational system from the school level to the college level.

Key Points

• According to NEP 2020, Children from 3 to 18 years old will have access to a free and compulsory high-quality education.
• This implies that all children between the ages of 3 and 18 will be entitled to receive a quality education from the government, regardless of their socioeconomic status.
• Everyone has access to get-quality education for all children from the age of 3-18 years instead of 6-14 years as per the RTE 2009.

 Therefore, the Arrangement of free and compulsory education for 3-18-year-old students are the changes required to be made in RTE 2009 as per NEP 2020.

Additional Information

• Right to Education Act (RTE) provided free and compulsory education to children between the age group of 6-14 years in 2009 and enforced it as a fundamental right under Article 21-A.
• India became one of 135 countries to make education a fundamental right of every child when the Act came into force on 1 April 2010.

The NRF (National Research Foundation) will be governed, independently of the government, by a rotating Board of Governors consisting of the very best researchers and innovators across fields.

Key Points

•  The goal of the NRF will be to enable a culture of research to permeate through our universities.
• The primary activities of the NRF will be to:
  •  fund competitive, peer-reviewed grant proposals of all types and across all disciplines.
  •  seed, grow and facilitate research at academic institutions.
  • act as a liaison between researchers and relevant branches of government as well as industry; so as to allow breakthroughs to be optimally brought into policy and/or implementation.
  • recognize outstanding research and progress.

Thus, it is concluded that According to NEP‐2020, National Research Foundation (NRF) may be established to enable a culture of research to permeate through universities.

The passage says that there has been an immense change in the climate of the planet over the years. We humans are ourselves responsible for generating this problem. Finding the solution to this problem is the biggest challenge of our generation. Lastly, the passage concludes that if we don't correct this situation now, it will be too late to control the problem.
