Determine the mass, in kg, of HgO that must decompose to form 64.4 L O2 gas at STP. 2HgO(s) → 2Hg(l) + O2(g)

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom

The reaction will shift to the right
