Complete the following: XeF 4 + O 2 F 2 → XeF 2 + H 2 O →

The complete balanced reaction is: XeF 4 + O 2 F 2 → XeF 6 + O 2 Xenon-fluorine compounds: Xenon forms three binary fluorides, XeF 2 , XeF 4 and XeF 6 by the direct reaction of elements under appropriate experimental conditions. Xe ( g ) + F 2 ( g ) → 673 K , 1 bar XeF 2 ( s ) ( xenon in excess ) Xe ( g ) + 2 F 2 ( g ) → 873 K , 7 bar XeF 4 ( s ) ( 1 : 5 ratio ) Xe ( g ) + 3 F 2 ( g ) → 573 K , 60 - 70 bar XeF 6 ( s ) ( 1 : 20 ratio ) XeF 6 can also be prepared by the interaction of XeF 4 and O 2 F 2 at 143K. XeF 4 + O 2 F 2 → XeF 6 + O 2 The complete balanced reaction is: 2 XeF 2 + 2 H 2 O → 2 Xe + 4 HF + O 2 Xenon-fluorine compounds: Xenon forms three binary fluorides, XeF 2 , XeF 4 and XeF 6 which are colourless crystalline solids and sublime readily at 298 K. They are powerful fluorinating agents. They are readily hydrolysed even by traces of water. For example, XeF 2 is hydrolysed to give xenon, hydrogen fluoride and oxygen. . 2 XeF 2 ( s ) + 2 H 2 O ( l ) → 2 Xe ( g ) + 4 HF ( aq ) + O 2 ( g ) Note: In general, noble gases are the least reactive. Their inertness to chemical reactivity is attributed to the following reasons: The noble gases except helium ( 1 s 2 ) have completely filled ns 2 np 6 electronic configuration in their valence shell. They have high ionisation enthalpy and more positive electron gain enthalpy. The reactivity of noble gases has been investigated occasionally, ever since their discovery, but all attempts to force them to react to form the compounds were unsuccessful for quite a few years. In March 1962 , Neil Bartlett, then at the University of British Columbia, observed the reaction of xenon noble gas. After this discovery, a number of xenon compounds mainly with the most electronegative elements like fluorine and oxygen, have been synthesised. The compounds of krypton are fewer. Only the difluoride ( KrF 2 ) has been studied in detail. Compounds of radon have not been isolated but only identified (e.g., RnF 2 ) by radiotracer technique. No true compounds of Ar , Ne or He are yet known.

How does ozone react with the following: NO

The reaction of ozone with NO (nitric oxide) is also called chemiluminescent reaction. Nitric oxide concentration can be determined using the chemiluminescent reaction involving ozone. A sample containing nitric oxide is mixed with a large quantity of ozone. The nitric oxide reacts with the ozone to produce oxygen and nitrogen dioxide, accompanied by emission of light (chemiluminescence) which can be measured with a photodetector. The amount of light produced is proportional to the amount of nitric oxide in the sample. The reaction involved is: NO + O 3 → NO 2 + O 2 + light
