Ncert Solutions Chemistry Class 11th

·   $\Delta S$ is a state function because its value depends only on the state of the system and not on how it is reached.

· Entropy is an extensive property because its value depends on the quantity of matter present in the system.

Total kinetic energy associated with 'n' moles of monoatomic gas is =   $\frac{3}{2}nRT$

NH₃ can be liquefied most easily due to presence of strong intermolecular H-bonding among NH₃ molecules.

Correct order or atomic radii is

Tl > ln > Al > Ga > B

Li⁺ has the largest size in aqueous solution due to its high polarizing power.

Volume strength of H₂O₂ = Molarity * 11.2

$\therefore Molarity=\frac{V}{11.2}=\frac{20}{11.2}=1.78\approx 1.8$

The maximum prescribed concentration of manganese in drinking water is 0.05 ppm.

Kindly go therough the solution

NO is a neutral oxide. 

Kindly consider the following figure

$\frac{P_1}{T_1}=\frac{P_2}{T_2}\Rightarrow \frac{35}{300}=\frac{40}{T_2}$

$\therefore T_2=\frac{40*300}{35}=342.85K$

$T_2\left(°C\right)=69.707\approx 70°C$
