The RBI’s “Finances of Panchayati Raj Institutions (PRIs)” report analyzes data from 2.58 lakh Panchayats for 2020-21 to 2022-23, highlighting key findings. Panchayats heavily rely on grants (95%) due to limited own revenue sources like property taxes. Inter-state variations in devolution impact socio-economic outcomes. Inconsistent data poses challenges in assessing fiscal health. PRIs struggle with local tax revenue generation due to a limited tax base, administrative issues, and unclear guidelines. Revenue sources include Central and State government grants, and PRIs have the authority to impose taxes and fees.

The instructions of a teacher must be based on the child's abilities, aptitude and interest. His ability to grasp and apply things, his natural ability to justify learning and his interest to learn a particular thing could decide the teaching strategies, as the education these days has become more child-centered. The teacher must be aware of the child's abilities, aptitude, and interest, which is possible only through proper evaluation.

Clemmensen reduction is suitable for reductio n of carbonyls containing additional acidic functional group.

Cimetidine,zantac and ranitidine are antacids as they control the root cause of acidity These drugs prevent the interaction of histamine with the receptors present in the stomach walls Consequently there is a decrease in the amount of acid release by the stomach 

Aggregation of colloidal particles into insoluble precipitate by addition of some suitable electrolyte is called coagulation.

If free radical halogenation generate a chiral carbon, racemic mixture of halides are always formed due to equal probability of halogenation from both sides of planar free radical.

The correct answer is Option D
 When alum is added to raw water it reacts with the bicarbonates alkalinities present in water and forms a gelatinous precipitate.
It neutralizes all the suspended impurities of water resulting in their coagulation.

 If one considers following molecule, it is 

Symmetrical and thus
In the given species

The correct answer is option A
Compare straight line equation
(y = mx + c) with Kt = -log (Ct) + log(C0)
where,
K being constant,
"t" is equivalent to "y" in straight line equation
(-1) is slope for equation which is "m" in straight line equation
log (Ct) is x-component
& log (C0) is y-intercept.
 

For second order reaction half life is inversely related to concentration of reactant.

Mass of O₂=32 gm ∆H/gm = -483.636/32 = -15.11
Mass of O₃=48 gm ∆H/gm = -868.2/48 = -18.08
Mass of H₂O₂=34 gm, ∆H/gm = -347.33/34 = -10.21
We can say that II has highest amount of energy per gram of oxidising agent.

The correct answer is option B
Given,
λCo(NH3)4Cl2+=50       λClo-4 =70
λ∞= λCo(NH3)4Cl2+  + λClo-4
λ∞= 50             + 70
λ∞=120
(x) Cell constant = 1/A
0.02 = l/A
Resistance(R)   =33.5Ω
K =c.x              (x = is cell constant)

S  =49.7 mol/L

7-Bromocycloheptane-1,3,5-triene

If CO₂ is passed through slaked lime(calcium hydroxide Ca(OH)₂), it gives out calcium carbonate (CaCO₃) also called marble/limestone.

CO₂ + Ca(OH)₂→ CaCO₃+ H₂O

For geometry and shape of a molecule, both bond pair and lone pair of electron in valence shell of central atom.

The correct answer is option A
Let initial concentration be ao​
After concentration decreases by

Using first order kinetic equation,

[Ni⁰(CO)₄]
[Cr³⁺(NH₃)₂][Ni⁴⁺F₆]₃
[Ni²⁺(NH₃)₂][B⁺³F₄]₂
K₄[Ni⁺²(CN)₆]

IUPAC is 2-butanamine.

The correct answer is Option A.
Aromatic Primary amine will form the most stable diazonium salt because it releases water when it reacts with nitronium ions. If aliphatic primary amine reacts with nitrosonium ion it Also releases water but in this case water reacts with alkyl diazonium salt and it forms alcohol while benzene diazonium salt does not react with water at this temperature.

For isobaric process, we have ∆S =nC_pln(T₂/T₁)
T2 = 273+127 = 400K and T₁ = 273+227 = 300K
Applying pV = nRT at initial condition,
1×10 = n×0.0821×300
n = 0.40
Applying ∆S =nC_pln(T₂/T₁)
∆S =0.40×5/2R×ln(400/300) = 2.38 JK^-1

It is a simple Tischenko reaction

The mole concept, which we will introduce here, bridges that gap by relating the mass of a single atom or molecule in amu to the mass of a collection of a large number of such molecules in grams. As you learned, the mass number is the sum of the numbers of protons and neutrons present in the nucleus of an atom.

)bond enthalpy > )bond enthalpy hence, is stable.

Bond enthalpy of six (P— P) bond = 6 x 215 = 1290 k j mol^-1

Bond enthalpy of six (N — N) bond = 6 x 160
= 960 kJ mol^-1
Thus, P₄ is more stable than N₄.
