By apply the law of conservation of energy to calorimeter experiments, $q$ cadiun $+q_{\text{a}\text{v}\text{i}\text{c}\text{n}}=0.$ Compute for the $q$ of the reaction.

$\frac{a}{n}=0\mathrm{.}00n-1$

If the calorimetry experiment is carried out under constant pressure conditions, calculate $H$ for the reaction.

Given either the mitial and final temperatire measurements of a solution or the sign of the AH$.$n$.$ identify if a reaction is endothermic or exothermic.
