The first and second ionisation enthalpies of a metal are 496 and 4560

\mathrm{kJ}\,\mathrm{ mo}{\mathrm{l}^{ - \mathrm{1}}}

, respectively. How many moles of

HCl

and

{H_2}S{O_4},

respectively, will be needed to react completely with 1 mole of the metal hydroxide?

View answer and explanation

Correct option: D

1 and 0.5

Option D (1 and 0.5) is correct because the metal likely forms

MOH

and

M_2SO_4

due to its low first ionization enthalpy and high second ionization enthalpy, indicating it forms a +1 ion.
