The right answer is 2HgO → 2Hg + O2
Balancing a balance equation consists of finding the right stoichiometric coefficients. These coefficients (placed in front of each molecule) balance the number of each of the different atoms involved during a chemical reaction.
In this reaction, we find on both sides the same number of atoms: two oxygen atoms and two atoms of mercury.
