The chemical equation that is provided is :

4Fe(s) + 302(g) → 2Fe2O3(aq) + 1644.3 kJ

1. reactants :

In this equation, the reactants are iron or Fe and oxygen or O that react with one another to produce a new compound or product.

2. Products:

The single product is produced by the given equation after the reaction between Fe and O is Fe2O3 ferric or iron oxide.

3. states of matter (all)

Fe                                 4

O                                   3

Fe2O3                         2

5. subscripts:

Elements                      state

Fe                                  single

O                                   2

Fe2O3                         Fe = 2 and O = 3

6. yield :

The representation of yield is by the arrow between reactants and products that is: →

7. Exothermic or Endothermic:

The reaction generates the energy and gives it to the surrounding which confirms that the reaction is an exothermic reaction.
