propane tank inspector detected rust (Fe_(2)O_(3)^L) inside an empty tank.The empty cylinder valve was not closed, exposing the interior of the tank to humid air. Select the equation that describes in synthesis reaction for the formation of rust. A Fe_(2)O_(3)arrow 2Fe+O_(2) B 4Fe+3O_(2)arrow 2Fe_(2)O_(3) C FeCl_(2)+H_(2)Oarrow FeO+2HCl D Fe_(2)O_(3)+3COarrow 2Fe+3CO_(2)

The correct answer is B) $4Fe+3O_{2}\rightarrow 2Fe_{2}O_{3}$.<br /><br />In a synthesis reaction, two or more simple substances combine to form a more complex compound. In this case, iron (Fe) and oxygen (O2) combine to form iron(III) oxide (Fe2O3), which is the chemical formula for rust.<br /><br />The equation $4Fe+3O_{2}\rightarrow 2Fe_{2}O_{3}$ represents the synthesis reaction for the formation of rust. It shows that four atoms of iron (Fe) react with three molecules of oxygen (O2) to produce two molecules of iron(III) oxide (Fe2O3).
