Formation no2
WebJan 11, 2016 · Hi! In the course reader we used Hess's Law to find the ΔH for NO 2 formation with the net reaction N 2 (g) + O 2 (g) --> 2NO 2 (g). If we instead wanted to know the value of the standard enthalpy of formation for NO 2, would we take the net enthalpy (which was 68 kJ) and divide it by the 2 moles of NO 2 (and get 34 kJ)? Thank you! Top. … WebThe nitronium ion, [N O 2] +, is a cation.It is an onium ion because its nitrogen atom has +1 charge, similar to ammonium ion [NH 4] +.It is created by the removal of an electron from the paramagnetic nitrogen dioxide molecule NO 2, or the protonation of nitric acid HNO 3 (with removal of H 2 O).. It is stable enough to exist in normal conditions, but it is generally …
