How many H-atome can be exchanged by D-atom when the following compound is kept in $\stackrel{\Theta }{O}D/D_{2}O$  solution for long time?

The decomposition of hydrogen peroxide follows first order kinetics.

2H₂O₂(aq) $\stackrel{}{\to }$ 2H₂O $\left(\mathcal{l}\right)$ + O₂(g)

If the volume of O₂ gas liberated at S TP in first 2- minutes of the start of decomposition is 25.00ml, what should be the total volume of O₂ gas (in ml) collected in time, t >> T_1/2. (t_1/2 for the decomposition of H₂O₂ is 10 min)

If x = Group number of Europium (atomic number 63)

y = Period number of Americium (atomic number 95)

z = Most stable oxidation state shown by Gadolinium (atomic number 64)

The only INCORRECT information is

Which reagent can not be used to distinguish t-Butyl alcohol and isopropyl alcohol:

If Q is a colourless gas with rotten fish smell then select CORRECT statement.

Which of the following reduction methods is correctly matched against the given metals (commercial process)?

An equilibrium mixture contains 2.0 moles of A(g) and 4.0 moles of B(g). Now, 2.0 moles of A(g) is added in this equilibrium mixture and the system is allowed to re-achieve equilibrium at constant volume and temperature. Now, the volume of system is doubled at constant temperature. What should be the moles of B(g) at new equilibrium? The reaction involved is

$A\left(g\right)\stackrel{}{?}2B\left(g\right)$ .
