Calculate the enthalpy change for the thermite reaction: 2al(s)+fe2o3(s)→2fe(s)+al2o3(s), δh∘rxn=−850 kj when 10.0 mol of al undergoes the reaction with a stoichiometrically equivalent amount of fe2o3. express your answer to three significant figures and include the appropriate units.

Enthalpy change when 10.0 moles of aluminium reacts with stoichiometrically equivalent ferric oxide is .

Explanation:

Energy change of the reaction when 2 mole of aluminium reacts with 1 mol of ferric oxide :

Energy change of the reaction when 1 mole of aluminium reacts :

Enthalpy change when 10.0 moles of aluminium reacts with stoichiometrically equivalent ferric oxide:

thats a little if u want the answer just look it up on google thats what i do haha : )
