NVS PGT Chemistry Mock Test - 6 - NVS TGT/PGT MCQ

 is the same as 1 × 4 : 1 × 3 i.e., 4 : 3

Share of A 

Share of B 

Difference = 48 - 36 = 12

Alternatively:

Since the ratio is 4 : 3, the difference is 

The difference of the profits 

Q, R, S, T, U, and V are seated in a straight line facing North.

i) S is second to the right of T.

ii) T is second to the right of Q.

iii) R is to the immediate left of Q

iv) R is to the immediate left of Q and is second to the left of V.

Thus we can see there are two persons seating between S and V.

Hence, the correct answer is "Two".

The logic follows here is:

It is given that Rahul has 48% marks in 10th, an age of 28 years, and work experience of 5 years.

It is clearly mentioned in the criteria that 10^th marks should be greater than 50% for job P and greater than 60% for job Q. Rahul got 48% marks in 10^th.

Therefore, Rahul, neither qualifies for job P nor for job Q.

Hence, the correct answer is "Neither P nor Q".

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".

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

Refusing to help children unless they have tried themselves is the characteristic of an effective teacher.
It is better to try and fail than not try at all. A teacher must let the children try to do things and also to handle problems/situations in a controlled environment.

Standard temperature and pressure (STP) is defined as 0 degrees Celsius and 1 atmosphere of pressure. At STP, 1 mole of any gas occupies 22.4 liters.
First, calculate the number of moles of hydrogen gas (H2) in 67.2 liters:
67.2 L / 22.4 L/mole = 3 moles of H2
Each molecule of H2 contains 2 atoms of hydrogen. Therefore, 3 moles of H2 contains:
3 moles * (6.022 x 10^23 molecules/mole) * 2 atoms/molecule = 3.6132 x 10^24 atoms of hydrogen.

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

Cs is highly electropositive & forms ionic bond with Cs⁺ cation.

The correct answer is Option A.

Out of the given four compounds only the first one has a chiral carbon. Hence compound A is optically active and it can rotate the plane polarised light.
 

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

 

(i) Phosphine Oxide, R₃P=O, presents an important example of the participation of d-atomic orbitals of nonmetallic elements in π bonding. The presence of π bonding is detected with the help of evidence, such as reduction in the bond length, increase in the bond strength, and the stabilization of charge distribution. On these grounds, compared to ammine oxide phosphine oxide presents strong evidence of the presence of dπ - pπ bond, in very high stability of P = O.
(ii) Nitrogen has a unique ability to form Pπ−Pπ multiple bonds with itself and with other elements due to its small size and high electronegativity. 
(iii) N₂O₃ doesn't contain protons, so it is not a Brønsted acid. If N₂O₃ is dissolved in water, you get HNO₂ which is a weak acid, so it is an anhydride of an acid.
(iv) Ca₃N₂: The oxidation state is -3.

Hence, option B is correct.

K₂O + H₂O → KOH

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

At 100°C and 1 atmosphere pressure H₂O (l) ⇋ H₂O(g) is at equilibrium. For equilibrium

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

Hence, the correct answer is Atoms. 

The substance which forms the colloidal solution in water is starch. A colloidal solution is a solution in which the colloid mixes uniformly. All colloids have a Tyndall Effect, which is not exhibited by glucose. Starch is a colloid and thus when mixed with water can form the colloidal solution.

Rate constant is also known as velocity constant.

Coordination isomerism is possible when both positive and negative ions of a salt are complex ions and two isomers differ in distribution of ligands in the cation and the anion.

Action research in education can be defined as the process of studying a school situation to understand and improve the quality of the educative process. It is an attractive option for teacher researchers, school administrative staff, and other stakeholders in the teaching and learning environment to consider. . It provides practitioners with new knowledge and understanding about how to improve educational practices or resolve significant problems in classrooms and school. 

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 correct word is 'allegory'. An 'allegory' is a '​story, poem, or picture that can be interpreted to reveal a hidden meaning, typically a moral or political one'.

Rule- The object in the active voice becomes the subject in the passive voice and the subject in the active voice becomes the object in the passive voice.This is valid in both ways (Active to passive and vice-versa). Further, the verb is changed to the past participle form.
