Question

(i) How is nitric acid manufactured by Ostwald process ?
(ii) Write down the reaction of Ozone with black lead sulphide.
(iii) Draw a structure of $1F_7$.

Answer 1

$\left(i\right)$ Ostwald process
$4N{H}_3+5O_2⟶4NO+6H_{2}O$
$2NO+O_2⟶2N{O}_3$
$3N{O}_2+H_{2}O⟶2HN{O}_3+NO$
$\left(ii\right)$ Ozone oxidizes $PbS$
$3PbS+4O_3⟶3PbS{O}_4$
$\left(iii\right)$ Structure of $I{F}_7$ as shown in above image.
