Balanced Chemical Equation – Solution

2HgO → 2Hg + O2

The coefficients show the number of particles (atoms or molecules), and the indices show the number of atoms that make up the molecule. New substances are formed as a result of the rearrangement of the original atoms. As a result of a chemical reaction, atoms of chemical elements do not disappear anywhere and new ones do not appear, their number remains unchanged – this follows from the law of conservation of mass of substances.

Chemical Reaction Information

Mercury(Ii) Oxide = Mercury + Dioxygen

This is an oxidation-reduction (redox) reaction. HgO is an oxidizing agent, HgO is a reducing agent.

  • 2 HgII + 4 e– → 2 Hg0 (reduction)
  • 2 O-II – 4 e– → 2 O0 (oxidation)

Reaction Type

Decomposition

Substances that react are called starting materials or reactants. The substances that form as a result are called reaction products.
