$2C_2{H}_{2(g)}+O_{2(g)}4C{O}_{2(g)}+2H_2{O}_{(l)}$

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 $+172\mathrm{.}3kJ$

$1.$
