Volume strength of H₂O₂ = Molarity × 11.2

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

Rate of heat radiated at (227 + 273) K

$=7cals/\left(c{m}^{2}s\right)$

Let rate of heat radiated at (727+ 273)  K = xcals/ (cm²s)

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

Correct order of increasing field strength of ligands is : I– < OH– < NCS–

Correct order of basic strength in aqueous medium is

${\left(C{H}_3\right)}_{2}NH>C{H}_{3}N{H}_2>{\left(C{H}_3\right)}_{3}N>N{H}_3$

EAN = Atomic No. – Oxidation state + 2 * CN

= 26 – 2 + 2 * 6

= 36.
