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).

When balancing chemical equations our goal is to have the same number of each type of atom on both sides of the equation.
Only change the coefficients (these are the numbers in front substances).
