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

  1. Detailed information about the equation 2Hg2CO3 -> 4HgO + 4CO2 + 2O2 -> :
    The chemical equation represents the decomposition reaction of Mercury(II) carbonate (Hg2CO3) to form Mercury(II) oxide (HgO), Carbon dioxide (CO2), and Oxygen (O2). In this reaction, 2 mol of Mercury(II) carbonate decompose to produce 4 mol of Mercury(II) oxide, 4 mol of Carbon dioxide, and 2 mol of Oxygen.

  2. Reaction conditions:
    The reaction usually takes place when the temperature rises above room temperature.

  3. Reaction process:
    As the temperature increases, Mercury(II) carbonate starts to decompose. During the decomposition process, it produces Mercury(II) oxide, Carbon dioxide, and Oxygen. Mercury(II) oxide will appear as a red or orange solid, while Carbon dioxide and Oxygen will appear as gases and escape from the mixture.

  4. Phenomenon occurs:
    During the reaction process, you will see Mercury(II) oxide appearing as a red or orange solid, and you may see gas bubbles (Carbon dioxide and Oxygen) escaping from the mixture. This is the clearest sign that the decomposition reaction has taken place.

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

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

    • The equation indicates the reaction from mercury(II) hydroxide (Hg2CO3) to create mercury(II) oxide (HgO), carbon dioxide (CO2) and oxygen (O2).
    • Hg2CO3 is a solid, HgO is an orange-yellow solid, CO2 and O2 are both gases.
    • This reaction belongs to the decomposition reaction category.

  2. Reaction conditions

    • The condition for the reaction to occur is the need for high temperature. Mercury(II) hydroxide decomposes to form mercury(II) oxide, carbon dioxide and oxygen when heated.

  3. Reaction process

    • During the reaction process, two molecules of mercury(II) hydroxide will decompose to form four molecules of mercury(II) oxide, four molecules of carbon dioxide and two molecules of oxygen.

  4. Phenomenon occurrence

    • The phenomenon that occurs during the reaction is the appearance of carbon dioxide gas and oxygen gas. The initial solid will decrease and form a new orange-yellow solid (mercury(II) oxide).
