Consider the following reaction:

$2A{l}_{(s)}+F{e}_2{O}_3(s)A{l}_2{O}_3(s)+2F{e}_{(s)}$

In the boxes below write your answers to the following:

The total enthalpy change of the reactants $($sum of $($number of moles$)($heat of formation$)).$

The total enthalpy change of the products $($same form as $1).$

The enthalpy change of the total reaction.

Indicate if the reaction is exothermic or endothermic.

Give the answers to one decimal place, include the $+$ or $-$ sign, include units. Use the format $+172\mathrm{.}3kJ$

$1.$
