MCQ
The normality of $10\,lit.$ volume hydrogen peroxide is
  • A
    $0.176$
  • B
    $3.52$
  • ✓
    $1.78$
  • D
    $0.88$
✓

Answer

Correct option: C.
$1.78$
c
(c) ${H_2}{O_2} \to {H_2}O + \frac{1}{2}{O_2}$

$1 M$  ${H_2}{O_2}$solution $ = 2N = 34\,gm/litre = 11.2$

So Normality $ = \frac{{2 \times 10}}{{11.2}} = 1.78$

$B$ has a smaller first ionization enthalpy than $Be$. Consider the following statements :

$(I)$ It is easier to remove $2 \mathrm{p}$ electron than $2 \mathrm{s}$ electron

$(II)$ $2 \mathrm{p}$ electron of $\mathrm{B}$ is more shielded from the nucleus by the inner core of electrons than the $2 s$ electrons of $Be.$

$(III)\; 2 s$ electron has more penetration power than $2 \mathrm{p}$ electron.

$(IV)$ atomic radius of $\mathrm{B}$ is more than $\mathrm{Be}$
