The equation 2Hg2(NO2)2 -> 4HgO + 4NO2 + O2

  1. Detailed information about the equation 2Hg2(NO2)2 -> 4HgO + 4NO2 + O2 -> :

  • This reaction is a decomposition reaction of the compound Hg2(NO2)2 (Mercury(I) nitrite) decomposing into HgO (Mercury(II) oxide), NO2 (Nitrogen dioxide) and O2 (Oxygen).

  • From the equation, we see that the reaction ratio is 2 moles of Hg2(NO2)2 producing 4 moles of HgO, 4 moles of NO2 and 1 mole of O2.

  1. Reaction conditions:
  • This reaction usually occurs under the influence of high temperatures.
  1. Reaction process:

  • First, the Hg2(NO2)2 compound decomposes due to high temperatures.

  • Next, the Hg2(NO2)2 molecule turns into 2 molecules of HgO, 2 molecules of NO2 and 1 molecule of O2.

  • Finally, the reaction products HgO, NO2 and O2 are produced.

  1. Phenomena occurring:

  • As the temperature increases, the Hg2(NO2)2 compound will start to decompose, the reaction process will take place and the result is the formation of HgO, NO2 and O2.

  • The color change of the compound during the reaction and the release of brown-colored NO2 gas and O2 can be observed.
