How to Balance:
Hg + O2 → HgO
✅Word equation: Mercury + Oxygen gas → Mercury (II) oxide
✅ Type of Chemical Reaction: For this reaction we have a combination reaction.
✅ Balancing Strategies: To balance this equation it's probably easiest to begin by changing the coefficient in front of the HgO.
This is a combination reactions because the mercury (Hg) plus the oxygen gas (O2) come together to form the Mercury (II) oxide (MgO).
