\(H_2O_2\) behave like reducing agent in which of the following reactions:
\(Fe^{+2}+ H_2O_2 → Fe^{+3} + H_2O\)
\(H_2S+H_2O_2 → SO^{2-}_4+H_2O\)
\(HOCl + H_2O_2 → Cl^- + 2H_2O + O_2\)
\(Mn^{+2} + H_2O_2 → MnO_2 + H_2O\)
\(H_2O_2\) reduces \(HOCl\) to \(Cl^-\) and itself gets oxidised to \(O_2.\)
The correct option is (c ): \(HOCl + H_2O_2 → Cl^- + 2H_2O + O_2\)
Given below are two statements.
In the light of the above statements, choose the correct answer from the options given below:
Let one focus of the hyperbola $ \frac{x^2}{a^2} - \frac{y^2}{b^2} = 1 $ be at $ (\sqrt{10}, 0) $, and the corresponding directrix be $ x = \frac{\sqrt{10}}{2} $. If $ e $ and $ l $ are the eccentricity and the latus rectum respectively, then $ 9(e^2 + l) $ is equal to:
The largest $ n \in \mathbb{N} $ such that $ 3^n $ divides 50! is:
