The full form of ITCZ is The Intertropical Convergence Zone.

• It is the area encircling Earth near the Equator, where there is a convergence of the northeast and southeast trade winds takes place.
• The ITCZ was originally identified from the 1920s to the 1940s as the "Intertropical Front" but after the recognition in the 1940s and 1950s of the significance of wind field convergence in tropical weather production.

Aishwary Pratap Singh Tomar won the gold medal in the 50m rifle 3P event at the 2023 Asian Shooting Championship with a final score of 463.5. He defeated China's Tian Jiaming, who won the silver medal with a score of 462.7. Tomar's impressive performance at the Asian Shooting Championship made him the most successful Indian shooter at the event.

Cooperation Minister Amit Shah launched the ‘Bharat Organics’ brand of the newly launched National Cooperative Organics Ltd (NCOL).
It will have as many as 20 products in the market by December 2023. NCOL will pass on 50 per cent of its profit earned over the Minimum Support Price (MSP) of any crop directly into the bank account of the farmers, while the rest will be used for the growth of the organization.

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.

A complex compound in which the oxidation number of metal is zero is [Ni(CO)_4​]. In this complex, the oxidation number of both metal and ligand is zero.

The oxidation number of metal in the complexes K₄​[Fe(CN)₆​], K₃​[Fe(CN)₆​] and [Pt(NH₃)₄]Cl₂ are +2, +3 and +2 respectively.

Although CH₃O^- is weaker base than (CH₃)₃CO^- , former is stronger nucleophile due to smaller size.

It is pseudo first order reaction.

There are two types of synthetic resins used for removal of permanent hardness. They are cation exchange resins which are big molecules containing sulfonic acid group and an anion exchange resins which are also big molecules containing amino acids.

F, O and N are electronegative elements. Thus, HF molecules are associated by intermolecules H-bonding giving it a liquid state and thus highest boiling point out of HF, HCl.HBr and HI.
Similarly, H₂O has highest boiling point, and NH₃ has highest boiling point.

environmental chemistry basically deals with the interrelationship between chemical species generated by human activities or naturally.

Rate constant is also known as velocity constant.

^–OCN is ambident ligand & it shows linkage isomerism.

Correct Answer is A.

From the sizes of octahedral and tetrahedral voids, it is clear that the atoms occupying these voids will not touch each other as we have along body diagonal of FCC.

In order for an atom to have a high electron affinity, it needs to be in a position to accept electrons. The alkaline earth metals (like calcium and magnesium) have filled s subshells, so they are stable. If anything, the alkaline earths prefer to lose electrons and exist as cations.

Hydrogen peroxide has many uses one of the most important uses of hydrogen peroxide is that it acts as a source of power i.e. 90% of hydrogen peroxide is used as fuel and submarines, rockets and helicopters.

Ag⁺ is reduced to Ag by oxygen



Thus, except in (b), oxygen behaves as reducing agent.

[ Most stable free radical is formed as intermidiate ] Order of Bromination = I > III > II >

 The two sulfur atoms of thiosulfate exist in the oxidation state of sulfate (+6) and sulfide (−2) and do not change their respective oxidation states upon disproportionation.  

So difference in the oxidation states of two types of sulphur atoms will be

= (+6)- (-2) 

= +8

A carbon atom has four valence electrons. The number of valence electrons of any atom of an element can be determined by the period table group in which the element is classified. There are a total of 18 groups on the period table group.

1-Heptanol & 4-Heptanol are not chiral
2-Heptanol & 3-Heptanol are chiral compound.

SF₆ has an octahedral geometry.

Adsorption involve decrease in entropy because gas when gas adsorbed randomness decreases. Also it is exothermic process.

The correct answer is Option B.
 
∆T_b =(K_b × 1000 × W₂) / M₂ × W₁
⇒ M₂ = (K_b × 1000 × W₂) / ∆T_b × W₁
= (1.71 × 1000 × 2) / 1 × 100
= 34.2g
