Question 41

A chemist monitors the thermal decomposition of a gaseous oxide of nitrogen, $NxOy\text{N}_x\text{O}_y$ , at a constant temperature of $∘C400\ ^\circ\text{C}$ and a constant pressure.

Under these conditions, complete decomposition of 120 cm³ of the gaseous oxide yields 120 cm³ of nitrogen gas ( $N2\text{N}_2$ ) and 240 cm³ of oxygen gas ( $O2\text{O}_2$ ).

What is the empirical formula of this oxide of nitrogen?

$NO\text{NO}$

$N2O4\text{N}_2\text{O}_4$

$NO2\text{NO}_2$

$N2O\text{N}_2\text{O}$
