Answer:
+2
Explanation:
Oxygen ions always have the charge of -2. Since Fe is in the transition metal stage, it doesn't have a specific set of ions unless specifically shown. In the equation FeO, we would have to have a +2 charge when equalling the two atoms together. So when combines the charges would look like:

C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O
is a combustion reaction
Explanation:
In a combustion reaction a chemical substance (usually organic substances) are reacted with oxygen to form the most stable oxides and heat.
CH₄ + 2 O₂ → CO₂ + 2 H₂O
In a double displacement reaction two compounds exchange elements.
AB + CD → AC + BD
In a decomposition reaction a compound is split into simpler substances.
AB → A + B
In a synthesis reaction two elements are combined to form another compound. A + B → AB
In a single displacement reaction a compound exchange one of its elements.
AB + C → AC + B
