Iron (Fe) and diatomic oxygen (O2) combine to produce iron(III) oxide (Fe2O3). The table below compares the properties of these substances. Iron (Fe) Oxygen (O2) Iron(III) Oxide (Fe2O3) Melting Point (°C) 1538 −218.4 1565 Density (g/cm3) 7.83 0.00143 5.26 Appearance shiny, gray metal colorless, odorless gas red, odorless powder What can be concluded from this data? A. A chemical reaction occurred because iron(III) oxide has different properties than iron and diatomic oxygen. B. A chemical reaction occurred because iron(III) oxide has similar properties to iron and diatomic oxygen. C. A chemical reaction did not occur because iron(III) oxide is not a new substance. D. A chemical reaction did not occur because solid iron cannot chemically react with oxygen gas.
