Calculate the standard reaction free energy of the following chemical reaction:

2Al(s)+ Fe2O3(s) → Al2O3(s)+ 2Fe(s)

The question is incomplete, the complete question is:

Calculate the standard enthalpy change for a reaction? : Fe2O3(s) + 2Al(s) = Al2O3(s) + 2Fe(s).

The standard enthalpies of formation of Fe2O3 and Al2O3 are

-822 and -1669 KJ mol-1 respectively. State whether the reaction is exothermic or

endothermic

∆H°reaction= -847KJmol-1

Explanation:

Recall that ∆H°element =0KJ mol-1

Therefore

∆H°reaction = ∆H°products - ∆H°reactants

= (-1669)-(-822)= -847KJmol-1

The reaction is exothermic as ∆H°reaction is negative.

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.
