The reaction of white phosphorus with aqueous NaOH gives phosphine along with another phosphorus containing compound. The reaction type; the oxidation states of phosphorus in phosphine and the other product are respectively

Propyne and propene can be distinguished by

For a monatomic gas kinetic energy = E, the relation with rms velocity is

In Langmuir's model of adsorption of a gas on a solid surface

An electron moving with velocity 'v' is found to have a certain value of de-Broglie wavelength. The velocity to be possessed by the neutron to have the same de-Broglie wavelength is-

\(x \mathrm{CIO}_{4}^{-}+y \mathrm{MnO}_{2}+z \mathrm{OH}^{-} \longrightarrow x \mathrm{CIO}^{-}+y \mathrm{MnO}_{4}^{2-}+\frac{z}{2} \mathrm{H}_{2} \mathrm{O}\)

In this balanced equation x, y, z are-

In Cannizzaro’s reaction, the intermediate which is the best hydride donor is-

A piston is cleverly designed so that it extracts the maximum amount of work out of a chemical reaction, by matching P_external to the P_internal at all times. This 8cm diameter piston initially holds back 1 mol of gas occupying 1 L, and comes to rest after being pushed out a further 2 L at 25^oC.After exactly half of the work has been done, the piston has travelled out a total of-
