A chemist measures the energy change AH during the following reaction: 2 HgO(s) → 2 Hg(1)+O,(g) AH=182. kJ Use the information to answer the following questions. endothermic. This reaction is... x10 exothermic. Yes, absorbed. Suppose 56.6g of HgO react. Yes, released. Will any heat be released or absorbed? No. If you said heat will be released or absorbed in the second part of this question, calculate how much heat will be released or absorbed. kJ Round your answer to 3 significant digits.
ator%=Dassignment-take Not syncing The combustion of 0.1557 g benzoic acid increases the temperature of a bomb calorimeter by 2.50°C. Calculate the heat capacity of this calorimeter. (The energy released by combustion of benzoic acid is 26.42 kJ/g.) [References) Heat capacity = kJ/°C A 0.2155-g sample of vanillin (Cg Hg O3) is then burned in the same calorimeter, and the temperature increases by 3.20°C.
