1

mole of

PbS

is oxidised by

X

moles of

{O}_{3}

to get

Y

moles of

{O}_{2} .

X + Y =

Correct answer

8

Step-by-step solution

Given that, $1$ mole of $PbS$ is oxidised by $X$ moles of ${O}_{3}$ to get $Y$ moles of ${O}_{2} .$

The balanced chemical equation can be written as,

$PbS + 4{O}_{3} \to {PbSO}_{4} + 4{O}_{2}$

Here $x = 4, y = 4$

Hence,

$X + Y = 4 + 4 = 8$
