what compound is formed if you combine iron, sulphur and oxygen?

To determine the compound formed by combining iron, sulfur, and oxygen, we need to understand their typical oxidation states and the formation of ionic compounds.

First, let's determine the oxidation states of each element:
- Iron (Fe) commonly exists in the +2 or +3 oxidation state.
- Sulfur (S) usually has an oxidation state of -2.
- Oxygen (O) typically has an oxidation state of -2.

Based on these oxidation states, we can determine the compound formed by combining these elements.

Considering the oxidation states, if iron reacts with oxygen (O) to form a compound, it would most likely be an oxide. Iron(II) oxide (FeO) and iron(III) oxide (Fe2O3) are common examples.

On the other hand, if sulfur reacts with oxygen, it typically forms sulfur dioxide (SO2) or sulfur trioxide (SO3), depending on the reaction conditions.

So, if we combine iron, sulfur, and oxygen, the most probable compound formed would be a mixture of iron oxide (FeO or Fe2O3) and sulfur dioxide (SO2) or sulfur trioxide (SO3) depending on the specific reaction conditions.
