\( H_2O \rightarrow H_2 + \frac{1}{2}O_2 \)
1 mole \( H_2O \rightarrow \) 2 Faradays = \( 2 \times 96500 \, \text{C} \)
0.1 mole \( H_2O \rightarrow x \, \text{C} \)
\( x = \frac{2 \times 96500 \times 0.1}{1} = 19300 \, \text{C} = 1.93 \times 10^4 \, \text{C} \)
$\mathrm{KMnO}_{4}$ acts as an oxidising agent in acidic medium. ' X ' is the difference between the oxidation states of Mn in reactant and product. ' Y ' is the number of ' d ' electrons present in the brown red precipitate formed at the end of the acetate ion test with neutral ferric chloride. The value of $\mathrm{X}+\mathrm{Y}$ is _______ .
The graph between variation of resistance of a wire as a function of its diameter keeping other parameters like length and temperature constant is
While determining the coefficient of viscosity of the given liquid, a spherical steel ball sinks by a distance \( x = 0.8 \, \text{m} \). The radius of the ball is \( 2.5 \times 10^{-3} \, \text{m} \). The time taken by the ball to sink in three trials are tabulated as shown:
