Answer:
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)
Elements state
Fe solid
O gas
Fe2O3 aqueous
4. Coieficents (all)
Elements state
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.
