The equation 2Hg2CO3 -> 4HgO + 4CO2 + O2

  1. Detailed information about the equation 2Hg2CO3 -> 4HgO + 4CO2 + O2 ->

    • Hg2CO3: is Mercury (I) carbonate, consisting of 2 Hg+ ions and 1 CO3 2- ion. It is a white solid.
    • HgO: is Mercury (II) oxide, consisting of 1 Hg2+ ion and 1 O2- ion. It is a red or orange-yellow solid.
    • CO2: is Carbon dioxide, which is a colorless, odorless gas in its standard state.
    • O2: is Oxygen, which is a colorless, odorless, tasteless gas.

  2. Reaction conditions

    • This reaction usually occurs at high temperatures, such as in a furnace.

  3. Reaction process

    • 2 mol of Hg2CO3 when heated will transform into 4 mol of HgO, 4 mol of CO2 and 1 mol of O2.

  4. Phenomenon that occurs

    • When Mercury (I) carbonate is heated, the original solid disappears and is replaced by the appearance of yellow or red Mercury (II) oxide. At the same time, there is the release of CO2 and O2 gases.
