Question

Can xenon trioxide be prepared directly by reacting xenon with oxygen

Answer 1

hy here is the answer.....

• Xenon reacts directly with fluorine because fluorine is a very powerful oxidizing agent (hence it gets reduced and it gains an electron from Xenon). ... Xenon does not react directly with oxygen. Xenon reacts with water molecules in order to form xenon oxides.

Answer 2

Answer:

At temperatures above −35.9 °C, xenon tetroxide is very prone to explosion, decomposing into xenon gas and oxygen with ΔH = −643 kJ/mol:

XeO4 → Xe + 2 O2

Xenon tetroxide dissolves in water to formperxenic acid and in alkalis to form perxenatesalts:

XeO4 + 2 H2O → H4XeO6XeO4 + 4 NaOH → Na4XeO6 + 2 H2O

Xenon tetroxide can also react with xenon hexafluoride to give xenon oxyfluorides:

XeO4 + XeF6 → XeOF4 + XeO3F2XeO4 + 2XeF6 → XeO2F4 + XeOF4

Xenon tetroxide is a chemical compound ofxenon and oxygen with molecular formula XeO4, remarkable for being a relatively stablecompound of a noble gas. It is a yellowcrystalline solid that is stable below −35.9 °C; above that temperature it is very prone to exploding and decomposing into elemental xenon and oxygen (O2).[4][5]

All eight valence electrons of xenon are involved in the bonds with the oxygen, and the oxidation state of the xenon atom is +8. Oxygen is the only element that can bring xenon up to its highest oxidation state; evenfluorine can only give XeF6 (+6). Two other short-lived xenon compounds with an oxidation state of +8, XeO3F2 and XeO2F4, are accessible by the reaction of xenon tetroxide with xenon hexafluoride. XeO3F2 and XeO2F4can be detected with mass spectrometry. Theperxenates are also compounds where xenon has the +8 oxidation state.

hope!!...it helps uhh...❣️
