Is 3Fe + 2O2 → Fe3O4 ΔH = -1120.5kJ an exothermic or endothermic equation

If dH is negative it means the reaction is releasing heat so it is exothermic.

To determine whether the given equation is exothermic or endothermic, we need to consider the sign of the enthalpy change (ΔH) value.

In this case, the given enthalpy change value, ΔH = -1120.5 kJ, is negative.

A negative ΔH value indicates that energy is being released or given off during the reaction. Therefore, the reaction is exothermic.

In conclusion, the equation 3Fe + 2O2 → Fe3O4 ΔH = -1120.5 kJ is an exothermic equation.

To determine whether the equation 3Fe + 2O2 → Fe3O4 ΔH = -1120.5 kJ is exothermic or endothermic, you need to analyze the sign of the enthalpy change (ΔH).

In this case, the given value for ΔH is -1120.5 kJ.

If ΔH is negative (like in this case), it means that the reaction releases energy to the surroundings, resulting in a temperature increase. Therefore, the reaction is exothermic.

In summary, the equation 3Fe + 2O2 → Fe3O4 ΔH = -1120.5 kJ is an exothermic reaction.
