Activity 2. Hess LawTo estimate the heat of reaction, let us consider the following steps:(b) C 6 H 4 (OH) 2 (aq) -> C_{6}*H_{4}*O_{2}(aq) + H_{2}(g)Delta * H deg = 177kJ / m * ol(c) H 2 O 2 (aq) longrightarrow H_{2}*O(l) + 1/2 * O_{2}(g)Delta * H deg = - 94.6kJ / m * ol(d) H 2 (g)+ 1/2 * O_{2} (g) longrightarrow H 2 O(l)Delta * H deg = - 286kJ / m * ol1. Balance the equation2. Calculate the heat of the reaction3. Is the reaction endothermic or exothermic?
