A pair of compounds that can be used to generate a gas which has physiological effect on human beings is
- sodium trioxonitrate (V) and calcium chloride
- sodium dioxonitrate (III) and ammonium chloride
-
sodium trioxonitrate (V) and ammonium chloride
- sodium dioxonitrate (III) and potassium chloride
The correct answer is: C
Explanation
The reaction between NaNO\(_3\) and NH\(_4\)Cl gives NaCl and NH\(_4\)NO\(_3\).
Upon heating, NH\(_4\)NO\(_3\) yields 2 moles of H\(_2\)O and N\(_2\)O.
