Please help me understand why this is the correct answer. Question 1. If the change in internal energy is measured to be 0, and heat is absorbed by the system, which of the following reactions could be taking place? (Assume a closed container at constant temperature with a constant external pressure). Correct: BaCO3(s) → BaO(s) + CO2(g)Incorrect C2H4(g) + 3O2(g) → 2CO2(g) + 2H2O(l)Incorrect N2(g) + 2O2(g) → 2NO2(g)Incorrect C(s) + O2(g) → CO2(g)Incorrect None of these reactions could apply. 2) What is the molar mass of an unknown organic liquid based on the data from analysis of the liquid? Vaporization of 230.0 mg of the compound in a 120 mL bulb at 130°C gives a pressure of 440.0 torr.
