• The Archaeological Survey of India (ASI) have stated excavations in Benisagar – which is a village in Jharkhand’s West Singhbhum district. The excavation has yielded hundreds of artifacts indicating continuous human habitation from the fifth century A.D. until the 16-17 century A.D.
• Benisagar has been recognized by the ASI and listed among the top 100 significant archaeological monuments in the country.

Sharfuddoula has made history by becoming the first Bangladeshi umpire appointed to the ICC Elite Panel of Umpires. His selection was part of the ICC's annual review and selection process, marking a significant milestone in Bangladeshi cricket umpiring.

World Oral Health Day is observed annually on March 20th. It is a global initiative led by the World Health Organization (WHO) to raise awareness about oral health, promote the prevention and treatment of oral diseases, and address the increasing burden of oral health issues worldwide.

Schools act as an agent of socialization through the hidden curriculum. According to sociologists, the hidden curriculum is an unintended result of education. It is the process by which the norms and values of a society are taught to children, alongside the expectations of their particular society.

In education process aim, content and methods are evaluated.

Evaluation is concerned with assessing the effectiveness of teaching, teaching strategies, methods and techniques. It provides feedback to the teachers about their teaching and the learners about their learning.

Animals solve problems by understanding – like human beings, instead of going through either the trial and error process or stimulus response association. In this case, learning took place by insight. Learning by insight involves finding a solution to the problem by thinking over the problem and understanding the various aspects of the problematic situation.
Insight learning refers to the sudden realisation of the solution of any problem without repeated trials or continuous practices. To further elaborate on its definition, insight learning is the type of learning in which one draws on previous experience and also seems to involve a new way of perceiving logical and cause-and-effect relationship.

In A one and more different types of ligands are present.

• Ionic solids or compounds are formed by the transfer of electrons from one atom to another atom.
• Hence there is always the formation of anion and cation due to opposite charges electrostatic force of attraction formed between them which holds them together.

Therefore, the correct answer is B. 

Sum of number of neutrons and protons represents mass number. Tritium has 1 proton and 2 neutrons. 

(C—H) bond lengths are different from (B—H) and (N—H) bond lengths. Both are planar.

The symbol represents enthalpy of combustion which is always exothermic. For exothermic rxn delta H is always -ve. 

This is known as shielding effect. Inner lying electrons shields the positive charge reaching the outer most electrons.

Suppose x m. mole NaOH was added

In preference to reduction of Zn²⁺ at cathode, O^2- (aq) is oxidised to O₂ at anode.

Explanation: The atom which defines the structure of a family of organic compounds and their properties is called a functional group. Functional groups are specific groups of atoms or bonds within molecules that are responsible for the characteristic chemical reactions of those molecules.

Ferromagnetic substance get permanently magnetised in applied Magnetic Field.

In the presence of a catalyst, both the forward and reverse reaction rates will speed up equally, thereby allowing the system to reach equilibrium faster. However, it is very important to keep in mind that the addition of a catalyst has no effect whatsoever on the final equilibrium position of the reaction
A catalyst is not consumed in chemical reactions

Multimolecular colloids are formed when a large number of atoms or molecules of a substance aggregate together to form speices having size in colloidal range. sulphur sol contains a thousand of S8 molecules.

Explanation of Moseley's Straight-Line Graph

Moseley's law is an empirical law concerning the characteristic x-rays emitted by atoms. It states that the square root of the frequency of these x-rays is directly proportional to the atomic number of the element. In other words, the relationship between the atomic number and the frequency of the characteristic x-rays can be represented by a straight-line graph.

Option A: This would result in a curve, not a straight line, as the relationship between the atomic number and the frequency of characteristic X-rays is not linear.
Option B: This would also result in a curved graph, as the relationship between the square of the frequencies and the atomic number is not linear.
Option C: This is the correct answer because, according to Moseley's law, the square root of the frequency of characteristic X-rays is directly proportional to the atomic number of the element. Thus, plotting the square root of the frequencies against the atomic numbers will result in a straight-line graph.
Option D: This would not result in a straight-line graph, as the relationship between the reciprocal of the frequencies and the atomic number is not linear.

In summary, according to Moseley, a straight-line graph is obtained when plotting the square root of the frequencies of characteristic X-rays of elements against their atomic numbers. This relationship is expressed in Moseley's law and helps us understand the behavior of X-rays emitted by atoms.

Ionic hydrides are commonly known as saline hydrides or pseudohalides. These compounds form between hydrogen and the most active metals, especially with the alkali and alkaline-earth metals of group one and two elements.

In this group, the hydrogen acts as the hydride ion (H−). They bond with more electropositive metal atoms. Ionic hydrides are usually binary compounds (i.e., only two elements in the compound) and are also insoluble in solutions. Now I hope you can form your own examples, but common examples are Sodium Hydride (NaH), Lithium hydride (LiH), Potassium hydride (KH) etc.

Valence unpaired electrons are in 3p

Valence unpaired electrons are in 3p. 

Thus, (d).

Geometrical Isomers can be Diastereomers or Enantiomers.


Because geometrical isomers are around restricted rotation which can not be rotate or interconvertable.

Elements of group 1, i.e. Li, Na, K, Rb, Cs and Fr, are called alkali metals because they react with water to form alkaline solutions. The pH of solutions usually range between 8-12. 

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.

The correct answer is Option C.

in earth atmosphere hydrogen exists in combined form.
